DETAILED DESCRIPTION

(55) A description is now given of exemplary embodiments of the present inventions. It should be noted that although such terms as first, second, etc. may be used herein to describe various elements, components, regions, layers and/or units, it should be understood that such elements, components, regions, layers and/or units are not limited thereby because such terms are relative, that is, used only to distinguish one element, component, region, layer or unit from another region, layer or unit. Thus, for example, a first element, component, region, layer or unit discussed below could be termed a second element, component, region, layer or unit without departing from the teachings of the present inventions.

(56) In addition, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present inventions. Thus, for example, as used herein, the singular forms a, an and the are intended to include the plural forms as well, unless the context clearly indicates otherwise. Moreover, the terms includes and/or including, when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

(57) Hereinafter, a description is given of conventional procedure of acquiring and handling data performed by an inspection contractor with reference to FIG. 46. FIG. 46 illustrates a scheme of conventional inspection processing performed by the inspection contractor.

(58) When the inspection contractor inspects a tunnel, an inspector takes notes of observed conditions of the tunnel (comment of the tunnel) on a field inspection book, captures images of changed-portions of the tunnel as changed-portion photographs, and then creates a final inspection report, to be submitted to the national and local government offices, describing tunnel properties (e.g., name, location, length, age) using a tunnel ledger obtained from the government offices. The final inspection report includes, for example, an observed inspection findings chart, a photograph-captured position chart, a photograph ledger, and a tunnel inspection result summary table as illustrated in FIG. 46. The observed inspection findings chart includes the photograph-captured position chart.

(59) The inspection findings indicate any kind of findings observed on the tunnel surface, such as potential or imminent abnormalities (e.g., initial defects, aging defects, damages, deformations) that may cause problems, and non-abnormalities portions (e.g., stains) that may not cause problems. The final inspection report can be created using conventional procedure as illustrated in FIG. 46.

(60) (1) The observed inspection findings chart represents drawings of inspection findings (e.g., cracks) observed at portions during the inspection. When the inspection contractor creates the observed inspection findings chart, the inspection contractor refers to various field inspection records, such as the field inspection book, the observed-inspection findings photographs, and the tunnel ledger to draw lines representing the inspection findings (e.g., cracks), and input a width of the lines, such as crack lines using a computer-aided design (CAD) program.

(61) (2) The photograph ledger includes evaluation (assessment) results of the observed-inspection findings, such as cracks, associated with the observed-inspection findings photographs. The inspection contractor manually attaches the photographs including observed-inspection findings on the photograph ledger, and inputs diagnosis information including the evaluation results by referring to detail information of the inspection findings (comment) recorded on the field inspection book during the inspection. Further, to clarify which portion of the tunnel corresponds to the observed-inspection findings photograph attached to the photograph ledger, the observed inspection findings chart is added with an identification number of the observed-inspection findings photograph attached to the photograph ledger.

(62) (3) The tunnel inspection result summary table includes various information of the tunnel, such as tunnel properties (e.g., tunnel length) and the diagnosis information including the evaluation results. Specifically, the inspection contractor inputs the tunnel properties (e.g., tunnel length) in the tunnel inspection result summary table based on the tunnel ledger, and the diagnosis information including the evaluation results of the observed inspection findings based on the field inspection book.

(63) (4) In order to associate the inspection findings-observed portions related to the evaluation results and the observed-inspection findings photograph attached to the photograph ledger, the inspection contractor inputs an identification number associated with the observed-inspection findings photograph attached to the photograph ledger on the tunnel inspection result summary table.

(64) However, the observed-inspection findings may include some parts that need to be repaired immediately, such as cracks, while other parts that may be monitored alone without repairing. Typically, the number of other parts that may be monitored along the time line alone without repairing may gradually increase. Therefore, when the inspection contractor tries to draw a crack line or the like using computer aided design (CAD) of a personal computer or the like, the inspection contractor is required to draw a large number of findings, which takes a longer time to perform the drawing operation.

(65) Hereinafter, a description is given of a diagnosis system 1 according to an embodiment with reference to the drawings. In this description, the diagnosis and diagnostic may be interchangeably used.

(66) System Configuration:

(67) Hereinafter, a description is given of an example of a system configuration of the diagnosis system 1 with reference to FIG. 1. FIG. 1 is a schematic diagram of the diagnosis system 1 of the embodiment. In this description, the diagnosis includes any act or process of identifying the cause or nature of a condition, situation, or potential problem (such as abnormality) of an object such as structural object (e.g., tunnel). The examples of act or process of diagnosis include investigation, analysis, assessment (evaluation), etc. For example, assessment is any act or process of determining the condition, situation, or problem of the object, which is a target for diagnosis. In this description, the diagnosis system 1 can be also referred to as the assessment system. Further, in this description, for the simplicity of expression, the terms of diagnosis and assessment are interchangeably used.

(68) As illustrated in FIG. 1, the diagnosis system 1 includes, for example, an apparatus 3, and a diagnosis management server 5 connected with each other via a communication network 100 wirelessly and/or by wire. In this description, the apparatus 3 and the diagnosis management server 5 are examples of information processing apparatuses or terminals used for processing data and information related to the structural object (e.g., tunnel). In this description, the apparatus 3 can be used to draw or render images, and thereby the apparatus 3 can be referred to as a drawing apparatus, rendering apparatus, drawing assistance apparatus, or rendering assistance apparatus. Hereinafter, the apparatus 3 may be referred to as the drawing apparatus 3.

(69) The drawing apparatus 3 and the diagnosis management server 5 included in the diagnosis system 1 can communicate with each other via the communication network 100. The communication network 100 can be configured using a network, such as the Internet, a mobile communication network, a local area network (LAN), or the like. The communication network 100 can employ not only a wired communication network but also a wireless communication network, such as 3rd generation (3G), worldwide interoperability for microwave access (WiMAX: registered trademark), and long term evolution (LTE), or the like. Further, the drawing apparatus 3 can be configured to communicate information using short-range communication technology, such as near field communication (NFC: registered trademark).

(70) The drawing apparatus 3 can be used as a computer for receiving an input of various data, such as diagnosis target image, diagnosis region, and diagnosis information, to be described later. The drawing apparatus 3 may be installed with one or more application programs dedicated to image drawing or rendering. A user (e.g., operator) uses the drawing apparatus 3 to input various data related to the structural object (e.g., tunnel), such as a development-view image, generated by capturing the images of tunnel 8 from an entrance to an exit of the tunnel 8 and processing the captured images, and the detail information of the inspection findings (comment) recorded on the field inspection book by the inspector or assistant for the tunnel 8, and the detection data obtained by each sensor for the tunnel 8. In this description, the tunnel 8 is described as an example of the structural object, but the structural object is not limited thereto. In another example configuration, the data related to the structural object can be transmitted or input to another apparatus or device, such as the diagnosis management server 5, and then transferred from another apparatus or device to the drawing apparatus 3.

(71) As illustrated in FIG. 1, the inspector riding on the inspection vehicle 7 inspects the tunnel 8 by marking inspection findings (e.g., cracks) with a special chalk on a surface of the tunnel 8, and records a width of each crack in a field inspection book. While inspecting the tunnel 8, the inspector records detail information of the inspection findings indicating the status or condition of the inspection findings and evaluation results of the inspection findings (comment) in the field inspection book. Further, an assistant standing near the inspection vehicle 7 can write the detail information of the inspection findings (comment) spoken by the inspector in the field inspection book, and take pictures of the tunnel 8 in some cases. The inspection findings means any kind of findings observed on the tunnel surface, such as potential or imminent abnormalities (e.g., initial defects, aging defects, damages, deformations) that may cause problems, and non-abnormalities portions (e.g., stains) that may not cause problems.

(72) Then, an image capture vehicle 9 equipped with a camera unit (image capture device) travels from the entrance to the exit of the tunnel 8 while capturing images of the inner surface of the tunnel 8 from the entrance to the exit of the tunnel 8 to acquire images of the inner surface of the tunnel 8, which is to be described later with reference to FIG. 12. Hereinafter, images of the captured inner surface of the tunnel 8 are collectively referred to as a development-view image 201 of the tunnel (see FIG. 12), which corresponds to a panoramic image combining a plurality of images of a plurality of spans (formworks) of the tunnel 8. The development-view image 201 is generated by performing image processing on the plurality of mages of the inner surface of the tunnel 8 captured by the camera unit. Since the development-view image 201 includes portions marked with the special chalk by the inspector, the user of the drawing apparatus 3 can easily confirm positions and shapes of the inspection findings by checking the development-view image 201 after the inspection at the field. The development-view image 201 can be also be referred to as the image data of structural object (e.g., tunnel), which is an example of image data of the structural object generated using given image processing.

The span number is specified in the tunnel ledger managed by the government office or agency.

(99) The positional coordinates of the diagnosis region within the specific span indicate specific positional coordinates (e.g., start point) of the diagnosis region within the specific span when a given position within the specific span is set as the origin point.

(100) The height and width of the diagnosis region indicate the height and the width of a specific diagnosis region with respect to the origin point of the specific span related to the specific diagnosis region, in which the height and width of the diagnosis region indicate values identifying the entire specific diagnosis region.

(101) The photograph number is identification information identifying a photograph attached to the photograph ledger.

(102) The type of observed inspection findings and abnormality indicate a type of inspection findings and abnormality at the diagnosis target, such as inspection target object (or portion), inspected by the inspector.

(103) The evaluation result indicates an evaluation of the diagnosis target inspected by the inspector. Typically, the conditions of the diagnosis target are ranked using the evaluation levels of S, A, B, and C, in which S is the worst condition, and the condition becomes less severe in the order of S, A, B, and C, and the evaluation result may be also referred to as the assessment result in this description.

(104) The detail information of inspection findings (comment) is contents of information of inspection findings recorded by the inspector and/or the assistant (FIG. 1).

(105) The positional coordinates of the diagnosis region and the height and width of the diagnosis region within the span are an example of third position information XY3 (see FIG. 4) in this description.

(106) Diagnosis Target Element Management Table:

(107) FIG. 5 illustrates an example of a diagnosis target element management table 600T. The storage unit 5000 stores a diagnosis target element management database (DB) 5002 (FIG. 3) including the diagnosis target element management table 600T of FIG. 5. As illustrated in FIG. 5, the diagnosis target element management table 600T stores various items, such as diagnosis region number, span number (formwork number), element number, positional coordinates of a start point of a diagnosis target element image, positional coordinates of an end point of a diagnosis target element image, and width of a diagnosis target element image (millimeter: mm) in association with each other for each inspection date information.

(108) As to the information stored in the diagnosis target element management table 600T, the inspection date indicated by the inspection date information is the same date indicated as the inspection date in FIG. 4. The diagnosis region number and the span number (formwork number) in the diagnosis target element management table 600T are the same as those in the diagnosis information management table 500T (FIG. 4). The diagnosis information management table 500T (FIG. 4) and the diagnosis target element management table 600T (FIG. 5) are associated with each other using the diagnosis region number and the span number (formwork number).

(109) The element number is identification information identifying a diagnosis target element image, which is an element consisting the diagnosis target image. In this description, the diagnosis target element image corresponds to the diagnosis target element and the diagnosis target image corresponds to the diagnosis target.

(110) The positional coordinates of the start point of the diagnosis target element image indicate the coordinates of the start point when the diagnosis target element image is drawn in a specific span in the development-view image 201. For example, in an example case of FIG. 23, coordinates of a start point p21 indicate the start point of a first diagnosis target element image e21.

(111) The positional coordinates of the end point of the diagnosis target element image indicate the coordinates of the end point when the diagnosis target element image is drawn in the specific span in the development-view image 201. For example, in an example case of FIG. 23, coordinates of an end point p22 indicate the end point of the first diagnosis target element image e21.

(112) The width of the diagnosis target element (mm) indicates a width of a portion, such as cracks when the diagnosis target element is cracks. For example, in an example case of FIG. 23, a value is input to a width input field ws1 by a user. If the user inputs a numerical value in the width input field ws1, the reception unit 32 receives the input numerical value, and then the display control unit 34 displays the input numerical value (e.g., 0.5) as illustrated in FIG. 24.

(113) The start position coordinates of the diagnosis target element image and the end position coordinates of the diagnosis target element image specified for the element numbers 1 and 2 included in the diagnosis region number 1 are an example of first position information XY1 (FIG. 5) in this description.

(114) Functional Configuration of Diagnosis Management Server:

(115) Hereinafter, a description is given of a functional configuration of the diagnosis management server 5 with reference to FIG. 3.

(116) In the following description, each functional unit of the diagnosis management server 5 is described in relation with any of the components illustrated in FIG. 2 used for implementing each functional unit of the diagnosis management server 5.

(117) The communication unit 51 of the diagnosis management server 5 (FIG. 3), implemented by an instruction of the CPU 501 (FIG. 2) and the network I/F 509 (FIG. 2), transmits and receives various data or information to and from other device or terminal, such as the drawing apparatus 3, via the communication network 100.

(118) The generation unit 53, implemented by an instruction from the CPU 501 (FIG. 2), generates data of submission document (e.g., observed inspection findings chart, photograph ledger, tunnel inspection result summary table) to be submitted to the government office based on various data stored in the diagnosis information management DB 5001 and the diagnosis target element management DB 5002.

(119) The determination unit 55, implemented by an instruction from the CPU 501 (FIG. 2), performs a determination process when the generation unit 53 is to generate data of the submission document.

(120) The storing/reading unit 59, implemented by an instruction from the CPU 501 and the HDD 505 (FIG. 2), stores various data in the storage unit 5000, and reads out various data stored in the storage unit 5000.

(121) Processing and Operation:

(122) Hereinafter, a description is given of the processing or operation according to the embodiment with reference to FIGS. 6 to 33. FIG. 6 is an example of a sequence diagram illustrating a process of generating data of submission document. FIGS. 7A, 7B, 7C, and 7D (FIG. 7) illustrate a scheme of creating the submission document according to the embodiment.

(123) At first, as illustrated in FIGS. 6 and 7, the drawing apparatus 3 is input with data of the tunnel ledger acquired from the government office, the development-view image, and the comment (hereinafter, referred to as the data for the tunnel ledger) in accordance with a user operation (step S1). Hereinafter, the data input by the user using the drawing apparatus 3 may be referred to as field inspection data of the target tunnel.

(124) Then, the communication unit 31 of the drawing apparatus 3 uploads the data for the tunnel ledger (field inspection data of the target tunnel), input in step S1, to the diagnosis management server 5 (step S2). Then, the communication unit 51 of the diagnosis management server 5 receives the data for the tunnel ledger.

(125) In the diagnosis management server 5, the storing/reading unit 59 stores the data for the tunnel ledger, received in step S2, in the storage unit 5000 (step S3).

(126) Then, if the user inputs the diagnosis target image, the communication unit 31 of the drawing apparatus 3 requests the diagnosis management server 5 to transmit the data for the tunnel ledger in accordance with a user operation (step 4). Then, the communication unit 51 of the diagnosis management server 5 receives the request for the data for the tunnel ledger.

(127) Then, in the diagnosis management server 5, the storage/reading unit 59 reads out the data for the tunnel ledger, stored in the storage unit 5000 in step S3 (step S5).

(128) Then, the communication unit 51 transmits the data for the tunnel ledger, read out in step S5, to the drawing apparatus 3 (step S6). Then, the communication unit 31 of the drawing apparatus 3 downloads the data for the tunnel ledger.

(129) Then, as illustrated in FIG. 6, in accordance with the user operation, the drawing apparatus 3 performs a process of drawing a diagnosis target image on a part of the development-view image 201 (hereinafter, partial development-view image 202) and a process of inputting diagnosis information (step S7). The processing in step S7 will be described later in detail.

(130) Then, the communication unit 31 transmits a request for creating or generating a submission document to be submitted to the government office or the like to the diagnosis management server 5, together with the data of the drawn diagnosis target element image, and the data of the input diagnosis information (step S8). Then, the communication unit 51 of the diagnosis management server 5 receives the request for creating the submission document with the data of the diagnosis target element image and the data of the diagnosis information.

(131) Then, in the diagnosis management server 5, the storing/reading unit 59 stores the data of the diagnosis information and the data of the diagnosis target element image, respectively, in the diagnosis information management DB 5001 and the diagnosis target element management DB 5002 (step S9).

(132) Further, in order to create the submission document, the storing/reading unit 59 reads out the data of diagnosis information and the data of the diagnosis target element image, respectively from the diagnosis information management DB 5001 and the diagnosis target element management DB 5002, and also reads out the data for the tunnel ledger or the like from the storage unit 5000 (step S10).

(133) Then, the generation unit 53 of the diagnosis management server 5 creates or generates data of the submission document (e.g., observed inspection findings chart, photograph ledger, tunnel inspection result summary table), illustrated in FIG. 7A, using the data of diagnosis information, the data of the diagnosis target element image, and the data for the tunnel ledger, or the like (step S11).

(134) Then, the communication unit 51 transmits the data of the submission document to the drawing apparatus 3 (step S12). Then, the communication unit 31 of the drawing apparatus 3 receives the data of the submission document.

(135) Then, as illustrated in FIG. 7A, the drawing apparatus 3 prints out the data of the submission document to be submitted to the government office or the like (step S13). As illustrated in FIGS. 7B, 7C, and 7D, the submission document includes, for example, the tunnel inspection result summary table (FIG. 7B), the observed inspection findings chart (FIG. 7C), and the photograph ledger (FIG. 7D). By performing the above described processing, the inspection contractor can submit the data of the submission document to the government office using printed sheets. Alternatively, if the government regulation, such as the national government regulation, allows the submission of the data of the submission document to the government office using electronic data alone, the inspection contractor can submit the electronic data of the submission document to the government office without printing the data of the submission document.

(136) Drawing and Inputting of Diagnosis Information:

(137) Hereinafter, a description is given of the detail of step S7 with reference to FIGS. 8, 12 and 13. FIG. 8 is an example of a flowchart illustrating the steps of drawing an image and inputting diagnosis information. FIG. 12 is an example of a home screen SC1. FIG. 13 is an example of a diagnosis position input screen SC2 when a first input mode of a diagnosis target image (i.e., drawing of area) is selected.

(138) As indicated in FIG. 8, at first, in response to a user operation to the drawing apparatus 3, the display control unit 34 displays the home screen SC1 (FIG. 12) on the display 308 (step S21).

(139) As illustrated in FIG. 12, the home screen SC1 displays the development-view image 201 on the center of the home screen SC1. Further, as illustrated in FIG. 12, the home screen SC1 displays a total image screen SC10 showing an entire image of the development-view image 201 on the right upper corner of the home screen SC1.

(140) Further, as illustrated in FIG. 12, a plurality of selection buttons b0 to b6 is displayed on the upper left corner of the home screen SC1. The mode switching button b0 is used for switching a single mode (first mode) and a comparison mode (second mode), which will be described later in detail. The selection button b1 is used for selecting a first input mode for inputting an area for the diagnosis target image (i.e., drawing of area). The selection button b2 is used for selecting a second input mode for inputting a line for the diagnosis target image (i.e., drawing of line pattern). The selection button b3 is used for selecting a third input mode for inputting a diagnosis region. The home button b4 is used for returning to the home screen SC1. The reduction button b5 is used for reducing a display size of the development-view image 201. The enlargement button b6 is used for enlarging a display size of the development-view image 201.

(141) Further, as illustrated in FIG. 12, RELOAD button b11 is displayed at the lower center portion of the home screen SC1. The RELOAD button b11 is used for displaying a pull-down menu that lists data of the diagnosis region already uploaded to the diagnosis management server 5.

(142) Similarly, as illustrated in FIG. 12, SAVE button b12 is displayed at the lower center portion of the home screen SC1. The SAVE button b12 is used for collectively transmitting data of the diagnosis information, generated and temporarily stored in the drawing apparatus 3, to the diagnosis management server 5 to save the data of diagnosis region in the diagnosis management server 5.

(143) Further, a save list 210 is also displayed at the lower center portion of the home screen SC1. The save list 210 is used for displaying names of data of diagnosis regions downloaded from the diagnosis management server 5, and names of data of diagnosis regions temporarily stored in the drawing apparatus 3. When the user selects the save list 210 using the pointer po, the display control unit 34 displays a diagnosis position input screen SC2 (FIG. 13) showing the corresponding diagnosis region.

(144) Further, as illustrated in FIG. 12, a layer list LL1 is displayed on the right side of the home screen SC1. The layer list LL1 displays a list of types of inspection findings, such as defects. For example, the layer list LL1 displays the types of defects, such as crack, water leakage, and calcification. When a check box of the layer list LL1 is checked, a layer of the checked inspection findings (e.g., crack) is displayed over the development-view image 201. Further, as illustrated in FIG. 12, LAYER button b13 is displayed at the right lower side of the home screen SC1, and the LAYER button b13 is used for displaying the layer list LL1 using a pull-up display.

(145) When the user operates the mouse 312 to select a specific span, to be input with image drawing and diagnosis information, using the pointer po on the home screen SC1, the display control unit 34 displays the diagnosis position input screen SC2 on the display 308 as illustrated in FIG. 13 (step S22). The diagnosis position input screen SC2 (FIG. 13) displays the partial development-view image 202 corresponding to the selected span of the development-view image 201. Further, as illustrated in FIG. 13, a viewing direction switching button bc1 is displayed on the lower right corner of the diagnosis position input screen SC2, and the viewing direction switching button bc1 is used for switching the viewing direction of the development-view image 201. The switching of the viewing direction will be described later with reference to FIGS. 32 and 33.

(146) Then, if the user does not press the mode switching button b0 (step S23: NO) but selects any one of the selection buttons b1, b2, and b3 using the pointer po, the reception unit 32 receives a selection of the input mode (step S24). Therefore, if the user does not press the mode switching button b0, the drawing apparatus 3 enters the input mode using the single mode (first mode).

(147) Then, if the user performs drawing of image and inputting of diagnosis information in accordance with the selected input mode, the drawing apparatus 3 performs the drawing of image and the inputting of diagnosis information (step S25). The detail of step S25 will be described later for each input mode.

(148) Then, if the user does not press the mode switching button b0 in step S23 (not selecting the comparison mode (second mode)), that is, if the single mode (first mode) is set (step S26: NO), and the reception unit 32 receives an operation of the mouse 312 or the like performed by the user, the storing/reading unit 39 temporarily stores, in the storage unit 3000, data of the new diagnosis region generated by performing the drawing of image and the inputting of diagnosis information (step S27), and then the drawn image data of the new diagnosis information is transmitted to the diagnosis management server 5 from the drawing apparatus 3 in step S8 described in FIG. 6.

(149) Input Mode of Diagnosis Target Image (Drawing of Area):

(150) Hereinafter, a description is given of the details of step S24 (FIG. 8) when the first input mode for inputting an area of the diagnosis target image (i.e., drawing of an area) is selected with reference to FIGS. 9, and 13 to 20. The first input mode for inputting an area of the diagnosis target image (i.e., drawing of an area) can be referred to as the first input mode of the diagnosis target image in this description. The first input mode of the diagnosis target image (i.e., drawing of an area) is used when the diagnosis target corresponds to inspection findings that can be identified as a certain area, such as calcification and water leakage.

(151) FIG. 9 is an example of a flowchart illustrating processing of the first input mode of the diagnosis target image (i.e., drawing of an area). FIG. 13 is an example of the diagnosis position input screen SC2 when the first input mode of the diagnosis target image (i.e., drawing of an area) is selected. FIGS. 14 to 19 are examples of screens when inputting the diagnosis target image (i.e., drawing of an area) on the diagnosis position input screen SC2. FIG. 20 is another example of a diagnosis information input screen, which is referred to as the diagnosis information input screen SC4.

(152) At first, when a user selects the selection button b1 in step S23 (FIG. 8) using the pointer po, the display control unit 34 sets the first input mode of the diagnosis target image (i.e., drawing of an area) as illustrated in FIG. 13.

(153) In this case, as illustrated in FIG. 14, when the user identifies a start point p11 of a first diagnosis target element image e11 using the pointer po, the reception unit 32 receives the input of the start point p11 of the first diagnosis target element image e11 (step S101).

(154) Then, the display control unit 34 displays an enter button co11 and a cancel button ca11 near the start point p11 (step S102). The enter button co11 is used for entering the input of the diagnosis target element image to confirm the input of the diagnosis target image. The cancel button ca11 is used for cancelling the input of the identified start point p11. Further, other enter buttons and other cancel buttons can be respectively used in the same way as the enter button co11 and the cancel button ca11 in this description.

(155) Then, as illustrated in FIG. 15, if the user identifies an end point p12 of the first diagnosis target element Image e11 using the pointer po, the reception unit 32 receives the input of the end point p12 of the first diagnosis target element image e11 (step S103).

(156) Then, the display control unit 34 displays the first diagnosis target element image e11 between the start point p11 and the end point p12 and also displays an enter button co12 and a cancel button ca12 near the center of the first diagnosis target element image e11 (step S104) as illustrated in FIG. 15. With this configuration, the user can draw the diagnosis target element image by identifying the start point and the end point of the diagnosis target element image.

(157) Then, the determination unit 35 determines whether the diagnosis target element image, displayed in step S104, includes a plurality of diagnosis target element images (step S105). At this time, since only one diagnosis target element image is displayed as illustrated in FIG. 15, the determination unit 35 determines that the diagnosis target element image does not include the plurality of diagnosis target element images (step S105: NO), and then the sequence proceeds to step S106.

(158) If the determination in step S105 is NO, the determination unit 35 determines whether pressing of the enter button is received by the reception unit 32 (step S106). If the determination unit 35 determines that the pressing of the enter button is received by the reception unit 32 (step S106: YES), the sequence proceeds to step S110, to be described later. On the other hand, if the determination unit 35 determines that the pressing of the enter button is not received by the reception unit 32 (step S106: NO), the sequence returns to step S103.

(159) As illustrated in FIG. 16, if the user identifies an end point p13 of a second diagnosis target element image e12 using the pointer po, the reception unit 32 receives the input of the end point p13 of the second diagnosis target element image e12. Since the start point of the second diagnosis target element image 12 matches the end point p12 of the first diagnosis target element image e11, the user can omit the identification of the start point of the second diagnosis target element image e12.

(160) Then, in step S104, the display control unit 34 displays the second diagnosis target element image e12 between the start point (i.e., end point p12) and the end point p13 and also displays an enter button co13 and a cancel button ca13 between the first diagnosis target element image e11 and the second diagnosis target element image e12 as illustrated in FIG. 16.

(161) Then, in step S105, the determination unit 35 determines whether the diagnosis target element image, displayed in step S104, includes a plurality of diagnosis target element images. At this time, since two diagnosis target element images (i.e., first diagnosis target element image e11 and second diagnosis target element image e12) are displayed as illustrated in FIG. 16, the determination unit 35 determines that plurality of the diagnosis target element images is displayed (step S105: YES).

(162) Then, the display control unit 34 automatically displays a third diagnosis target element image e13 (i.e., new diagnosis target element image) between the start point p11 of the first diagnosis target element image e11 and the end point p13 of the second diagnosis target element image e12 as illustrated in FIG. 16 (step S107), in which the third diagnosis target element image e13 is the latest diagnosis target element image.

(163) Further, the display control unit 34 changes the display positions of the enter button and the cancel button (step S108). Specifically, the display control unit 34 changes the enter button co12 and the cancel button ca12 illustrated in FIG. 15 to the enter button co13 and the cancel button ca13 illustrated in FIG. 16.

(164) Then, the determination unit 35 determines whether the pressing of the enter button is received by the reception unit 32 (step S109). If the determination unit 35 determines that the pressing of the enter button is not received by the reception unit 32 (step S109: NO), the sequence returns to step S103.

(165) As illustrated in FIG. 17, if the user identifies an end point p14 of the third diagnosis target element image e13 using the pointer po, the reception unit 32 receives the input of the end point p14 of the third diagnosis target element image e13. Since the start point of the third diagnosis target element image e13 matches the end point p13 of the second diagnosis target element image e12, the user can omit the identification of the start point of the third diagnosis target element image e13.

(166) Then, in step S104, the display control unit 34 displays the third diagnosis target element image e13 between the start point (i.e., end point p13) and the end point p14 and also displays an enter button co14 and a cancel button ca14 between the first diagnosis target element image e11, the second diagnosis target element image e12, and the third diagnosis target element image e13 as illustrated in FIG. 17.

(167) Then, in step S105, the determination unit 35 determines whether the diagnosis target element image, displayed in step S104, includes the plurality of the diagnosis target element images. At this time, since three diagnosis target element images (i.e., first diagnosis target element image e11, second diagnosis target element image e12, and third diagnosis target element image e13) are displayed, the determination unit 35 determines that the diagnosis target element image, displayed in step S104, includes the plurality of the diagnosis target element images (step S105: YES).

(168) Then, in step S107, the display control unit 34 automatically displays a fourth diagnosis target element image e14 (i.e., new diagnosis target element image) between the start point p11 of the first diagnosis target element image e11 and the end point p14 of the third diagnosis target element image e13 as illustrated in FIG. 17, in which the fourth diagnosis target element image e14 is the latest diagnosis target element image.

(169) Further, in step S108, the display control unit 34 changes the display positions of the enter button and the cancel button. Specifically, the display control unit 34 changes the enter button co13 and the cancel button ca13 illustrated in FIG. 16 to the enter button co14 and the cancel button ca14 illustrated in FIG. 17.

(170) Then, as illustrated in FIG. 18, if the user presses the enter button co14 using the pointer po, the reception unit 32 receives the pressing of the enter button co14, and then the determination unit 35 determines that the pressing of the enter button co14 is received by the reception unit 32 (step S109: YES).

(171) Then, as illustrated in FIG. 19, the determination unit 35 confirms or identifies a diagnosis target image (i.e., drawing of area), and the display control unit 34 displays the confirmed diagnosis target image dt11 (step S110).

(172) Then, as illustrated in FIG. 19, the display control unit 34 displays a rectangular-shaped diagnosis region da11 including the diagnosis target image dt11, and a diagnosis information input screen SC3 (step S111). In this case, in order to make the diagnosis information input screen SC3 conspicuous, the display control unit 34 can apply a masking on a portion other than the diagnosis information input screen SC3. In this description, the diagnosis information input screen SC3 may be referred to as a first input screen, and the diagnosis information input screen SC3 and other similar screens can be also referred to as the input screen, the input section, or the input box depending on purposes of the screens, in which the size of screen may be set smaller than a size of the display 308.

(173) The user, such as the operator, uses the diagnosis information input screen SC3 to input the diagnosis information by referring to the detail information of inspection findings (e.g., comment) recorded by the inspector or the assistant. As illustrated in FIG. 19, the diagnosis information input screen SC3 displays, for example, a selection button to link with the previous or past diagnosis information, a first pull-down menu for selecting an inspection (diagnosis) object, a second pull-down menu for selecting an inspection (diagnosis) portion, a third pull-down menu for selecting a type of observed-inspection findings and abnormality, a first input field for inputting an evaluation result, and a second input field for inputting the detail information of inspection findings (e g, comment). The link with the previous or past diagnosis information is used when adding a new diagnosis target image into the already confirmed diagnosis region. For example, the link with the previous or past diagnosis information can be used when water leakage is already confirmed as one diagnosis target image in one diagnosis region, and then crack is added as a new diagnosis image in the same one diagnosis region including the water leakage.

(174) Further, as illustrated in FIG. 19, the diagnosis information input screen SC3 displays OK button for confirming the input diagnosis information, and CANCEL button for canceling the input diagnosis information. The diagnosis information can be also referred to as the assessment information. In this case, if the user selects and inputs the diagnosis information in the diagnosis information input screen SC3 and presses the OK button, the reception unit 32 receives the selection and input of the diagnosis information (step S112).

(175) Further, as illustrated in FIG. 19, the diagnosis information input screen SC3 displays an input switching button bm for switching from the diagnosis information input screen SC3 to a diagnosis information input screen SC4 illustrated in FIG. 20. If the input switching button bm (FIG. 19) is pressed, the display control unit 34 switches the diagnosis information input screen SC3 to the diagnosis information input screen SC4 (FIG. 20).

(176) The diagnosis information input screen SC4 is used when one diagnosis region includes a plurality of diagnosis target images, and the diagnosis information is input for each one of the diagnosis target images. For example, when one diagnosis region includes three diagnosis target images (e.g. cracks, calcifications, water leaks), the diagnosis information input screen SC4 is used to collectively control or manage the one diagnosis region including the three diagnosis target images. In this case, when data of the diagnosis information is uploaded from the drawing apparatus 3 to the diagnosis management server 5 at a later time, the diagnosis management server 5 controls or manages the three diagnosis target images (e.g., cracks, calcifications, water leaks) included in the same diagnosis region having the diagnosis region number of 3 as illustrated in FIG. 4.

(177) Similar to the diagnosis information input screen SC3, the diagnosis information input screen SC4 displays OK button for confirming the input diagnosis information, and CANCEL button for canceling the input diagnosis information as illustrated in FIG. 20. Further, as illustrated in FIG. 20, the diagnosis information input screen SC4 displays an input switching button bs for switching from the diagnosis information input screen SC4 to the diagnosis information input screen SC3 (FIG. 19). If the input switching button bs (FIG. 20) is pressed, the display control unit 34 switches the diagnosis information input screen SC4 (FIG. 20) to the diagnosis information input screen SC3 (FIG. 19).

(178) By performing the above described processing, the drawing of the diagnosis target image dt11 and the diagnosis region da11 and the selection and input of the diagnosis information are completed for the first input mode of the diagnosis target image (i.e., drawing of an area).

(179) Input Mode of Diagnosis Target Image (Drawing of Line Pattern):

(180) Hereinafter, a description is given of the detail of step S24 (FIG. 8) when the second input mode for inputting a line pattern of the diagnosis target image (i.e., drawing of a line pattern) is selected with reference to FIGS. 10, and 21 to 26. The second input mode for inputting the line pattern of the diagnosis target image (i.e., drawing of a line pattern) can be referred to as the second input mode of the diagnosis target image in this description. The second input mode of the diagnosis target image (i.e., drawing of a line pattern) is typically used when the diagnosis target is crack, but not limited thereto.

(181) FIG. 10 is an example of a flowchart illustrating processing of the second input mode of the diagnosis target image (i.e., drawing of a line pattern). FIG. 21 is an example of the diagnosis position input screen SC2 when the second input mode of the diagnosis target image (i.e., drawing of a line pattern) is selected. FIGS. 22 to 26 are examples of screens when inputting the diagnosis target image (i.e., drawing of a line pattern) on the diagnosis position input screen SC2.

(182) At first, in step S23 (FIG. 8), if the user selects the selection button b2 using the pointer po, the display control unit 34 sets the second input mode of the diagnosis target image (i.e., drawing of a line pattern) as illustrated in FIG. 21.

(183) Then, as illustrated in FIG. 22, if the user identifies a start point p21 of a first diagnosis target element image e21 using the pointer po, the reception unit 32 receives the input of the start point p21 of the first diagnosis target element image e21 (step S201).

(184) Then, the display control unit 34 displays an enter button co21 and a cancel button ca21 near the start point p21 (step S202).

(185) Then, as illustrated in FIG. 23, if the user identifies an end point p22 of the first diagnosis target element image e21 using the pointer po, the reception unit 32 receives the input of the end point p22 of the first diagnosis target element image e21 (step S203).

(186) Then, as illustrated in FIG. 23, the display control unit 34 displays the first diagnosis target element image e21 and a width input field ws1 between the start point p21 and the end point p22 and also displays an enter button co22 and a cancel button ca22 near the center of the first diagnosis target element image e21 (step S204). With this configuration, the user can draw the diagnosis target element image by identifying the start point and the end point.

(187) The width input field ws1 is used for inputting a width of the line pattern when the diagnosis target element is, for example, crack. For example, the width input field ws1 is displayed near the first diagnosis target element image e21 and between the start point p21 and the end point p22. The user can input a value of width in the width input field ws1 by referring to the numerical value shown in the development-view image 201 (e.g., numeral value written by a special chalk) and the detail information of inspection findings (e.g., comment). When the user inputs the numerical value in the width input field ws1, the reception unit 32 receives the input numerical value, and the display control unit 34 displays the input numerical value (e.g., 0.5) as illustrated in FIG. 24.

(188) Then, the determination unit 35 determines whether the pressing of the enter button is received by the reception unit 32 (step S205). If the determination unit 35 determines that the pressing of the enter button is not received by the reception unit 32 (step S205: NO), the sequence returns to step S203.

(189) In an example case of FIG. 24, if the user identifies an end point p23 of a second diagnosis target element image e22 using the pointer po, the reception unit 32 receives the input of the end point p23 of the second diagnosis target element image e22. Since the start point of the second diagnosis target element image e22 matches the end point p22 of the first diagnosis target element image e21, the user can omit the identification of the start point of the second diagnosis target element image e22.

(190) Then, in step S204, the display control unit 34 displays the second diagnosis target element image e22 and a width input field ws2 between the start point p22 (i.e., end point p22) and the end point p23 and also displays an enter button co23 and a cancel button ca23 between the first diagnosis target element image e21 and the second diagnosis target element image e22 as illustrated in FIG. 24. If the user inputs a numerical value into the width input field ws2, the reception unit 32 receives the input numerical value, and the display control unit 34 displays the input numerical value (e.g., 0.7) as illustrated in FIG. 25. Further, if the diagnosis target element image is an image having a given area size, an area-value input field can be set and displayed as needed. Further, if the diagnosis target element image is an image having a given length, a length-value input field can be set and displayed as needed.

(191) As illustrated in FIG. 25, if the user presses the enter button co23 using the pointer po, the reception unit 32 receives the pressing of the enter button co23, and then the determination unit 35 determines that the pressing of the enter button co23 is received by the reception unit 32 (step S205: YES).

(192) Then, the determination unit 35 confirms or identifies the diagnosis target image (i.e., drawing of a line pattern), and the display control unit 34 displays the confirmed diagnosis target image dt21 (step S206) as illustrated in FIG. 26.

(193) Further, the display control unit 34 displays a rectangular-shaped diagnosis region da21 including the diagnosis target image dt21 and the diagnosis information input screen SC3 (step S207). In this case, in order to make the diagnosis information input screen SC3 conspicuous, the display control unit 34 can apply a masking on a portion other than the diagnosis information input screen SC3.

(194) In this case, if the user selects and inputs the diagnosis information on the diagnosis information input screen SC3 and presses the OK button, the reception unit 32 receives the selection and input of the diagnosis information (step S208).

(195) By performing the above described processing, the drawing of the diagnosis target image dt21 and the diagnosis region da21 and the selection and input of the diagnosis information are completed for the second input mode of the diagnosis target image (i.e., drawing of line pattern).

(196) Input Mode of Diagnosis Region:

(197) Hereinafter, a description is given of the detail of step S24 (FIG. 8) when the third input mode of the diagnosis region is selected with reference to FIGS. 11, and 27 to 31. The third input mode of the diagnosis region is used when the diagnosis target image is identified after identifying the diagnosis region in this description.

(198) FIG. 11 is an example of a flowchart illustrating the steps of processing of the third input mode of the diagnosis region. FIG. 27 is an example of the diagnosis position input screen SC2 when the third input mode of the diagnosis region is selected.

(199) FIGS. 28 to 31 are examples of screens when inputting the diagnosis region on the diagnosis position input screen SC2.

(200) At first, in step S23 (FIG. 8), if the user selects the selection button b3 using the pointer po, the display control unit 34 sets the third input mode of the diagnosis region as illustrated in FIG. 27.

(201) Then, as illustrated in FIG. 28, if the user identifies a first vertex p31 of a tentative (or provisional) diagnosis region da03 (see FIG. 29) using the pointer po, the reception unit 32 receives the input of the first vertex p31 of the tentative diagnosis region da03 (step S301).

(202) Then, the display control unit 34 displays an enter button co31 and a cancel button ca31 near the first vertex p31 (step S302) as illustrated in FIG. 28.

(203) Then, as illustrated in FIG. 29, if the user identifies a second vertex p32, which is a diagonal vertex relative to the first vertex p31 of the tentative diagnosis region da03, using the pointer po, the reception unit 32 receives the input of the second vertex p32 as the diagonal vertex of the first vertex p31 of the tentative diagnosis region da03 (step S303).

(204) Then, as illustrated in FIG. 29, the display control unit 34 displays the tentative diagnosis region da03 as a rectangular shaped region having the first vertex p31 and the second vertex p32 as the diagonal vertexes, and also displays an enter button co32 and a cancel button ca32 near the center of the tentative diagnosis region da03 (step S304). With this configuration, the user can draw the diagnosis region by identifying the two vertexes, each being the diagonal angles.

(205) Then, the determination unit 35 determines whether the pressing of the enter button is received by the reception unit 32 (step S305). If the determination unit 35 determines that the pressing of the enter button is not received by the reception unit 32 (step S305: NO), the sequence returns to step S303. In this case, after the user has identified the second vertex p32, the first vertex p31 or the second vertex p32 is changed to enlarge or reduce an area of the tentative diagnosis region da03.

(206) On the other hand, as illustrated in FIG. 30, if the user presses the enter button co32 using the pointer po, the reception unit 32 receives the pressing of the enter button co32, and then the determination unit 35 determines that the pressing of the enter button co32 is received by the reception unit 32 (step S305: YES).

(207) Then, the determination unit 35 confirms or identifies the tentative diagnosis region da03 (step S306).

(208) Further, as illustrated in FIG. 31, the display control unit 34 displays a diagnosis region da3 having a rectangular shape, which is the same as the confirmed tentative diagnosis region da03, and the diagnosis information input screen SC3 (step S307). In this case, in order to make the diagnosis information input screen SC3 conspicuous, the display control unit 34 can apply a masking on a portion other than the diagnosis information input screen SC3.

(209) In this case, if the user selects and inputs the diagnosis information on the diagnosis information input screen SC3 and presses the OK button, the reception unit 32 receives the selection and input of the diagnosis information (step S308).

(210) By performing the above described processing, the drawing of the diagnosis region da3 and the selection and input of the diagnosis information are completed for the third input mode of the diagnosis region. Thereafter, as similar to the first input mode of the diagnosis target image (i.e., drawing of an area) and the second input node of the diagnosis target image (i.e., drawing of a line pattern), the user can draw the diagnosis target image in the diagnosis region da3.

(211) Change of Viewing Direction:

(212) Hereinafter, a description is given of process of shifting or changing of viewing directions of the development-view image 201 with reference to FIG. 32 (32A to 32C) and FIG. 33 (33A to 33B). FIG. 32A illustrates a relationship between the tunnel 8 and the viewing directions, FIG. 32B illustrates a schematic diagram of the tunnel 8 viewed from the lower direction of the tunnel 8, and FIG. 32C illustrates a schematic diagram of the tunnel 8 viewed from the upper direction of the tunnel 8. FIGS. 33A and 33B (FIG. 33) are examples of diagnosis target images obtained by switching the viewing directions, in which FIG. 33A is an example of the diagnosis target image viewed from the lower direction of the tunnel 8, and FIG. 33B is an example of the same diagnosis target image viewed from the upper direction of the tunnel 8.

(213) As illustrated in FIG. 32, the development-view image 201 is an image that is acquired by looking up the wall and ceiling of the tunnel 8 from the inside of the tunnel 8. This image is referred to as a look-up image. However, the observed inspection findings chart to be submitted to the government office might be required to be an image viewed from the outside of the tunnel 8 (i.e., above the tunnel 8) as illustrated in FIG. 7. This image is referred to as a look-down image.

(214) As illustrated in FIG. 32A, the tunnel 8 can be viewed from a look-up position of the tunnel 8 such as from an inside 81 of the tunnel 8, and from a look-down position of the tunnel 8 such as from an outside 82 of the tunnel 8, in which the look-up position views the tunnel 8 into a upward direction from the inside 81 of the tunnel 8 and the look-down position views the tunnel 8 into a downward direction from the outside 82 of the tunnel 8. Since the tunnel 8 is typically built in undergrounds, such as hills and mountains, the look-down position may be a virtual position in some cases.

(215) As illustrated in FIG. 32A, when the inside 81 of the tunnel 8 is viewed along the viewing direction sd1, the development-view image 201 becomes the look-up image as illustrated in FIG. 32B. In this case, the directions of virtual arrows va1 and va2 in FIG. 32A, respectively, become the upward direction at the bottom left, and the downward direction at the upper right in FIG. 32B.

(216) Further, when the same portion is viewed from the outside 82 of the tunnel 8 along the viewing direction sd2, the development-view image 201 becomes the look-down image as illustrated in FIG. 32C. In this case, the directions of virtual arrows va1 and va2 in FIG. 32A, respectively, become the downward direction at the upper left, and the upward direction at the bottom right in FIG. 32C. That is, the look-up image and the look-down image are the inverted images.

(217) When the display control unit 34 switches or inverts the top and bottom of the development-view image 201 while displaying the development-view image 201 on the display 308, the display control unit 34 displays the diagnosis target element image by changing the y-coordinate of the development-view image 201 from Y to Y for the two-dimensional coordinates (X, Y) of the diagnosis target element image stored in the storage unit 3000.

(218) If the user presses a viewing direction switching button (switch to look-down button) bc1 on the diagnosis position input screen SC2 indicated in FIG. 33A, the reception unit 32 receives the pressing of the viewing direction switching button bc1, and then the display control unit 34 switches or converts the image view from a look-up image 222a (FIG. 33A) to a look-down image 222b (FIG. 33B). Further, when the user presses a viewing direction switching button (switch to look-up button) bc2 on the diagnosis position input screen SC2 indicated in FIG. 33B, the reception unit 32 receives the pressing of the viewing direction switching button bc2, and then the display control unit 34 switches or converts the image view from the look-down image 222b (FIG. 33B) to the look-up image 222a (FIG. 33A). With this configuration, the user can draw the diagnosis target element image and the diagnosis region using any one of the look-up image and the look-down image. In this case, the coordinates of positions of the diagnosis target element image and diagnosis region stored in the storage unit 3000 are not changed, but the display control unit 34 changes the display style alone.

(219) Attaching Attachment Image to Photograph Ledger:

(220) Hereinafter, a description is given of a process of attaching an attachment image to the photograph ledger, which is a part of the processing of data of the final inspection report illustrated in step S11 of FIG. 6, with reference to FIGS. 34 and 35. FIG. 34 is an example of a flowchart illustrating the steps of attaching an attachment image to the photograph ledger. FIG. 35 is an example of a diagram illustrating a relationship between the diagnosis target image, the diagnosis region, and the attachment image.

(221) As illustrated in FIG. 34, the generation unit 53 identifies a specific diagnosis region in the development-view image 201 (i.e. captured tunnel surface image) based on data of positional coordinates of the specific diagnosis region and data of height and width of the specific diagnosis region read from the diagnosis information management DB 5001 (step S401).

(222) Then, in accordance with an aspect ratio of the attachment image, the generation unit 53 creates an attachment image with a given size, defined by the aspect ratio of the attachment image, which can enclose the specific diagnosis region within the attachment image (step 402). For example, in a case of the diagnosis region da11 including the diagnosis target image dt11 illustrated in FIG. 19, the generation unit 53 generates or creates an attachment image at1 so that two opposite sides of the diagnosis region da11 corresponds to two opposite sides of the attachment image at11 having a rectangular shape as illustrated in FIG. 35.

(223) Then, the determination unit 55 determines whether the diagnosis region is located at a position in the upper half of the development-view image 201 (step S403).

(224) If the determination unit 55 determines that the diagnosis region is located at the position of the upper half of the development-view image 201 (step S403: YES), the generation unit 53 inverts the top and bottom of the attachment image generated in step S402 (step S404). That is, the generation unit 53 converts the attachment image so that the top and bottom of the attachment image becomes the same as the top and bottom of the structural object that is viewed from a viewing direction of a person who views the structural object from the bottom of the structural object.

(225) For example, as illustrated in FIG. 32, if an attachment image P is located at a position in the lower half of the development-view image 201, the attachment image P is attached to the photograph ledger without inverting the top and bottom of the attachment image P. By contrast, if an attachment image G is located at a position in the upper half of the development-view image 201, the top and bottom of the attachment image G is required to be inverted because the diagnosis region is displayed in the development-view image 201 by inverting the top and bottom of the diagnosis region.

(226) Then, the generation unit 53 attaches the attachment image at a given position in the development-view image 201 (step S405).

(227) On the other hand, if the determination unit 55 determines in step S403 that the diagnosis region is not located at the position in the upper half of the development-view image 201 (step S403: NO) (i.e., the diagnosis region is located at the position in the lower half of the development-view image 201), the generation unit 53 performs the processing in step S405.

(228) Then, the attachment of the attachment image to the photograph ledger is completed. With this configuration, an error that might occur when creating the photograph ledger including the diagnosis information of the structural object can be reduced compared to conventional method.

(229) Processing in Comparison Mode:

(230) Hereinafter, a description is given of the processing of the input mode when the comparison mode (second mode) is selected with reference to FIGS. 8, 36 to 45. Hereinafter, among the first input mode of the diagnosis target image (area) (FIG. 9), the second input mode of the diagnosis target image (line pattern) (FIG. 10) and the third input mode of the diagnosis region (FIG. 11), the comparison mode (second mode) is performed for the second input mode of the diagnosis target image (line pattern), but the comparison mode (second mode) can be also performed for the first input mode of the diagnosis target image (area) and the third input mode of the diagnosis region.

(231) In FIG. 8, if the user presses the mode switching button b0 using the pointer po and enters the comparison mode (second mode) (step S23: YES), the display control unit 34 displays a previous image selection screen SP, for example, near the mode switching button b0 as illustrated in FIG. 36 (step S28). The previous image selection screen SP displays information (e.g., inspection date) identifying the latest development-view image, information (e.g., inspection date) identifying the previous development-view image, and a comparison execution button b11 indicated as execute comparison in FIG. 36. The latest development-view image is an image to which a diagnosis target image is to be input as the latest diagnosis target image. The previous development-view image is an image in which the diagnosis target image was input in previously or the past, and the previous development-view image stored previously or in the past can be selected from a pull-down menu. The comparison execution button b11 is a button which is pressed by a user when comparing the latest development-view image and the selected previous development-view image.

(232) If the user opens the pull-down menu of the previous development-view image using the pointer po, the display control unit 34 displays information (e.g., inspection date) specifying a plurality of previous images captured previously or in the past as shown in FIG. 37 (step S29).

(233) Then, if the user selects the desired inspection date using the pointer po, the reception unit 32 receives the selection of the previous development-view image to be compared with the latest development-view image (step S30).

(234) Then, if the user presses the comparison execution button b11 using the pointer po, the storing/reading unit 39 reads out the previous development-view image selected in step S30, together with the diagnosis information (see FIG. 4) and the diagnosis target element (see FIG. 5) of the selected previous development-view image from the storage unit 3000 (step S31).

(235) Then, as indicated in FIG. 38 and FIG. 39, the display control unit 34 displays, on the diagnosis position input screen SC5, a diagnosis target image (diagnosis target) in the previous development-view image (first development-view image) and a diagnosis target image (diagnosis target) in the latest development-view image (second development-view image), by superimposing the diagnosis target image in the previous development-view image and the diagnosis target image in the latest development-view image, which are corresponded with each other (step S32).

(236) Hereinafter, a description is given of superimposing and displaying of images with reference to FIG. 39. FIG. 39 shows an example of the previous development-view image and the latest development-view image displayed in a hierarchical manner. FIG. 39A is an example of a diagnosis target image in the previous development-view image, FIG. 39B is an example of a schematic diagram of the diagnosis target image in the previous development-view image corresponding to FIG. 39A, FIG. 39C is an example of a diagnosis target image in the latest development-view image, and FIG. 39D is an example of a schematic diagram of the diagnosis target image in the latest development-view image corresponding to FIG. 39C.

(237) At the time of initial displaying indicated in FIG. 38, as shown in FIG. 39, the lowest display layer is the previous development-view image of FIG. 39A, the middle display layer is the previous diagnosis target image in the same previous image, and the top display layer is the latest development-view image of FIG. 39C. At this time, the latest diagnosis target image of FIG. 39D is not yet drawn. When the latest diagnosis target image of FIG. 39D is drawn, the latest diagnosis target image of FIG. 39D is displayed as an image of the top display layer.

(238) Further, as illustrated in FIG. 38, a transmittance rate setting region TR is displayed at the upper part of the diagnosis position input screen SC5. The transmittance rate setting region TR includes, for example, a transmittance setting pointer tp used for inversely changing a display transmittance (first display transmittance) of a set of the previous development-view image and the previous diagnosis target image in the same previous image, and a display transmittance (second display transmittance) of a set of the latest development-view image and the latest diagnosis target image (in case where the latest diagnosis target image is drawn).

(239) Hereinafter, a description is given of the relationships between (1) the position of transmittance setting pointer, (2) the development-view image and diagnosis target image, and (3) the display transmittance with reference to FIG. 40. FIG. 40 indicates the relationships between the position of the transmittance setting pointer tp, the development-view image and the diagnosis target image, and the display transmittance.

(240) At first, as shown in FIG. 40A, when the transmittance setting pointer tp is moved to the most left-side end of a bar, the display transmittance (first display transmittance) of the set of the previous development-view image and the previous diagnosis target image in the same previous image becomes 0%, and the display transmittance (second display transmittance) of the latest development-view image becomes 100%. In this description, when the display transmittance becomes 100%, the display state substantially becomes a state that no image is displayed, which means the image set with the display transmittance of 100% is not displayed.

(241) Then, as shown in FIG. 40B, when the transmittance setting pointer tp is moved to the center position between the most left-side end and the very center of the bar, the display transmittance of the set of the previous development-view image and the previous diagnosis target image in the same previous image becomes 25%, and the display transmittance of the latest development-view image becomes 75%. In this case, as shown in FIG. 40B, a crack that has not shown in the previous development-view images in FIG. 40A is displayed with a thin display density in the latest development-view image while the previous diagnosis target image captured previously or in the past is displayed with slightly thinner display density. Since the diagnosis target portion (e.g. crack) of the previous development-view image is displayed both in the previous development-view image and the latest development-view image, the diagnosis target portion (e.g. crack) of the previous development-view image is not displayed with thinner display density even if the display transmittance of the previous development-view image and the display transmittance of the latest development-view image are changed.

(242) Then, as shown in FIG. 40C, when the transmittance setting pointer tp is moved to the very center of the bar (the initial display state), the display transmittance (first display transmittance) of the set of the previous development-view image and the previous diagnosis target image in the same previous image becomes 50%, and the display transmittance (second display transmittance) of the latest development-view image becomes 50%. In this case, in the latest development-view image, the diagnosis target portion (e.g. crack) that has not appeared in the previous development-view image in FIGS. 40A and 40B, can be displayed more clearly while the previous diagnosis target image captured previously or in the past is displayed with further thinner display density.

(243) Then, as shown in FIG. 40D, when the transmittance setting pointer tp is moved to the center between the very center and the most right-side end of the bar, the display transmittance (first display transmittance) of the set of the previous development-view image and the previous diagnosis target image in the same previous image becomes 75%, and the display transmittance (second display transmittance) of the latest development-view image becomes 25%. In this case, in the latest development-view image, the diagnosis target portion (e.g. crack) that has not appeared in the previous development-view images in FIGS. 40A, 40B and 40C, can be displayed further clearly while the previous diagnosis target image captured previously or in the past is displayed with further thinner display density.

(244) Then, as shown in FIG. 40E, when the transmittance setting pointer tp is moved to the most right-side end of the bar, the display transmittance (first display transmittance) of the set of the previous development-view image and the previous diagnosis target image in the same previous image becomes 100%, and the display transmittance (second display transmittance) of the latest development-view image becomes 0%. In an example case of FIG. 40, the display transmittance level is changed in five stages, but the display transmittance level can be changed in two or more stages.

(245) As described above, the further the transmittance setting pointer tp is moved closer to the left-side end of the bar, the display transmittance (first display transmittance) of the set of the previous development-view image and the previous diagnosis target image (if drawn) becomes gradually lower, and the display transmittance (first display transmittance) becomes 0% at the most left-side end of the bar. In this case, the display transmittance (second display transmittance) of the set of the latest development-view image and the latest diagnosis image set (if drawn) is inversely and gradually becomes higher, and the display transmittance (second display transmittance) becomes 100% at the most left-side end of the bar.

(246) On the other hand, the further the transmittance setting pointer tp is moved closer to the right-side end of the bar, the display transmittance (first display transmittance) of the set of the previous development-view images and the previous diagnosis target image becomes gradually higher, and the display transmittance (first display transmittance) becomes 100% at the most right-side end of the bar. In this case, the display transmittance (second display transmittance) of the set of the latest development-view image and the latest diagnosis image set (if drawn) is inversely and gradually becomes lower, and the display transmittance (second display transmittance) becomes 0% at the most right-side end of the bar. At the time of the initial display, the display transmittance (first display transmittance) of the previous development-view image and the previous diagnosis target image in the same previous image is set to 50%, and the display transmittance (second display transmittance) of the latest development-view image is also set to 50%. As above described, when the first display transmittance changes from 0 to 100%, the second display transmittance changes from 100% to 0%.

(247) Then, as indicated in FIG. 8, after performing step S32, the sequence proceeds to step S24. Hereinafter, a description is given of a process of changing the display transmittance in step S25 with reference to FIGS. 41 to 44. FIG. 41 is an example of a flowchart illustrating the steps of changing the display transmittance of a diagnosis target image on the diagnosis position input screen SC5.

(248) As illustrated in FIG. 41, the reception unit 32 waits for receiving a change of the position of the transmittance setting pointer tp during the processing in step S25 (step S41: NO). If the reception unit 32 receives the change in the display transmittance caused by changing the position of the transmittance setting pointer tp (step S41: YES), the display control unit 34 changes the display transmittance as above described with reference to FIG. 40 (step S42). Then, the reception unit 32 waits until the reception unit 32 receives the next time for changing the position of the transmittance setting pointer tp (step S41: NO).

(249) Hereinafter, a description is given of a drawing process of a specific diagnosis target image with reference to FIGS. 42 to 44. FIGS. 42 to 44 show examples of screens used for inputting a diagnosis target image on the diagnosis position input screen that is set in the comparison mode (second mode). Specifically, FIG. 42 is an example case of the comparison mode with respect to the single mode (first mode) in FIG. 22, FIG. 43 is an example case of the comparison mode with respect to the single mode (first mode) in FIG. 23 or FIG. 24, and FIG. 44 is an example case of the comparison mode with respect to the single mode (first mode) in FIG. 26.

(250) Hereinafter, it is assumed that the display transmittance of the previous development-view image and the display transmittance of the latest development-view image are respectively set to 50%, and if a user designates the end point p23 of the diagnosis target element image e22 in the previous development-view image as the new start point p23 using the pointer po as shown in FIG. 42, the reception unit 32 receives an input of the start point p23 of the latest diagnosis target element image e23 on the latest development-view image (step S201 in FIG. 10).

(251) Then, the display control unit 34 displays an enter button co23 and a cancel button ca23 near the start point p23 (step S202 in FIG. 10).

(252) Then, as shown in FIG. 43, if the user identifies an end point p24 of the latest diagnosis target element image e23 using the pointer po, the reception unit 32 receives an input of the end point p24 of the latest diagnosis target element image e23 (step S203 in FIG. 10).

(253) Then, the display control unit 34 displays the latest diagnosis target element image e23 and a width input field ws3 between the start point p23 and the end point p24 and displays an enter button c24 and a cancel button ca24 near the center of the latest diagnosis target element image e23 (step S204 in FIG. 10). Then, the user can draw the latest diagnosis target element image e23 by designating the new start point p23 and the new end point p24 based on the previous diagnosis target element images e21 and e22. In this case, the user can find new findings, such as crack or the like, in the latest development-view image in comparison with the previous development-view image by moving the transmittance setting pointer tp in the transmittance rate setting region TR to the left and right directions.

(254) The width input field ws3 can be displayed near the latest diagnosis target element image e23 between the start point p23 and the end point p24. If the user enters a numerical value into the width input field ws3, the reception unit 32 receives an input of the numerical value, and the display control unit 34 displays the input numerical value (e.g., 0.6) as shown in FIG. 44.

(255) Then, the determination unit 35 determines whether the pressing of the enter button is received by the reception unit 32 (step S205 in FIG. 10). If the determination unit 35 determines that the pressing of the enter button is not received by the reception unit 32 (step S205: NO), the sequence returns to step S203.

(256) Then, if the user presses the enter button co24 using the pointer po in FIG. 43, the reception unit 32 receives the pressing of the enter button co24, and then the determination unit 35 determines that the pressing of the enter button co24 is received by the reception unit 32 (step S205: YES).

(257) Then, the determination unit 35 confirms or identifies a diagnosis target image (i.e., drawing of a line pattern), and the display control unit 34 displays the confirmed diagnosis target image dt22 (step S206 in FIG. 10) as shown in FIG. 44.

(258) Further, the display control unit 34 displays a rectangular-shaped diagnosis region da22 including the diagnosis target image dt22 and the diagnosis information input screen SC3 (step S207 in FIG. 10) as shown in FIG. 44. In this case, in order to make the diagnosis information input screen SC3 conspicuous, the display control unit 34 can apply a masking on a portion other than the diagnosis information input screen SC3.

(259) In this case, if the user selects and inputs the diagnosis information on the diagnosis information input screen SC3 and presses the OK button, the reception unit 32 receives the selection and input of the diagnosis information (step S208 in FIG. 10).

(260) By performing the above described processing, the drawing of the diagnosis target image dt22 and the diagnosis region da22 and the selection and input of the diagnosis information are completed for the second input mode of the diagnosis target image (i.e., drawing of line pattern) in the comparison mode (second mode). As above described, the user can draw the diagnosis target image dt22 consisted of the diagnosis target element images e21, e22, and e23 by re-using the diagnosis target element images e21 and e22 as the previous image portion and drawing the diagnosis target element image e23 alone as the new or latest image portion.

(261) Further, if the user presses the mode switching button b0 in step S23 and selects the comparison mode (second mode), that is, if the comparison mode (second mode) is set (step S26: YES) in the sequence of FIG. 8, the storing/reading unit 39 adds new information to the diagnosis information and the information of diagnosis target element image related to the previous development-view image selected in step S30 to temporarily store the new-information-added information in the storage unit 3000 as a separate file (step S33 in FIG. 8). For example, if the information of diagnosis target element image consisting the diagnosis target image shown in FIG. 39B corresponds to the positional coordinates indicated by the element numbers 1 and 2 of the diagnosis region number 1 (an example of first position information XY1) indicated in FIG. 5, the storing/reading unit 39 adds new information of the positional coordinates indicated by the element number 3 corresponding to the same diagnosis region number 1 (an example of second position information XY2 in FIG. 45) to the positional coordinates indicated by the element numbers 1 and 2 of the same diagnosis region number 1 as illustrated in FIG. 45 as the new or latest diagnosis target element image, which consists the diagnosis target image as shown in FIG. 39D, and stores the new-information-added information in the storage unit 3000 as a separate file. This completes the sequence of FIG. 8.

(262) Further, as illustrated in FIG. 39D, the display control unit 34 displays the previous diagnosis target image portion dp1 using the first position information XY1 (FIG. 45) and also displays the latest diagnosis target element image portion dp2 using the second position information XY2 (FIG. 45).

(263) As to the above described embodiment, by using the drawing apparatus 3, the user can draw the diagnosis target image indicating the diagnosis target on the image data (e.g., development-view image) of the structural object (e.g., tunnel), and can input the diagnosis information including the diagnosis result of the diagnosis target. As described above, since the user can directly draw the diagnosis target image indicating the diagnosis target identified on the development-view image, mistakes or errors that might occur during the document creation process can be reduced compared to the conventional methods of creating the final inspection report including the observed inspection findings chart or the like by comparing and checking a large number of documents and screens using hands and eyes of the user alone.

(264) Further, by associating and storing the coordinates of positions of the diagnosis region and the diagnosis information of the diagnosis region using the drawing apparatus 3, the workload for creating the submission document including the diagnosis information of the structural object, such as the tunnel 8, can be reduced compared to conventional methods.

(265) Further, since the photograph images attached to the photograph ledger use the images corresponding to the diagnosis regions on the development-view image 201, conventional manual work of pasting the observed-inspection findings photographs on the photograph ledger can be omitted, and thereby mistakes of pasting the observed-inspection findings photographs on the photograph ledger at a wrong position can be prevented.

(266) Further, since the partial development-view image 202 can be switched between the look-up image 222a (FIG. 33A) and the look-down image 222b (FIG. 33B) as illustrated in FIG. 33, the drawing of diagnosis target image and the inputting of diagnosis information of diagnosis target image can be performed using the development-view image 201 according to the user's preference or familiarity of the look-up image 222a and the look-down image 222b, and thereby mistakes or errors that might occur during the document creation process can be reduced, in particular, prevented. Further, when submitting the final inspection report to the government office, the drawing apparatus 3 can output the look-down image, required by the government office in some countries, so that the user's error in the final inspection report, such as user's misunderstanding of the image direction, can be prevented.

(267) Further, as illustrated in FIG. 7, since the development-view image 201 is the look-up image viewed from the inside of the tunnel and the attachment images attached to the photograph ledger register are required to be the look-down image viewed from the outside of the tunnel, report creating persons of the inspection contractor may be confused. Further, as described above, as indicated in FIG. 32, because some of the attachment images attached to the photograph ledger register are required to invert the top and bottom of the attachment images, the report creating persons of the inspection contractor may be further confused. By contrast, in the above described embodiment, since the diagnosis management server 5 can automatically prepare or create the submission document, mistakes or errors that might occur during the document creation process can be reduced, in particular, prevented.

(268) Further, the user can draw the diagnosis target image dt22 consisted of the diagnosis target element images e21, e22, and e23 by re-using the diagnosis target element images e21 and e22 as the previous diagnosis target element images and drawing the diagnosis target element image e23 alone as the new diagnosis target element image. With this configuration, compared to conventional methods of drawing all of the diagnosis target element images in the development-view image captured for the structural object as the inspection findings, the drawing of the inspection findings can be performed with less workloads in the above described embodiment.

(269) According to the above described example embodiment, compared to conventional methods of drawing all of the diagnosis target element images for the inspection findings in the development-view image captured for the structural object, the drawing of the diagnosis target element images for the inspection findings can be performed with less workloads.

(270) In the above described embodiment, the structural object is exemplified as the tunnel, but not limited thereto. For example, the structural object includes piping or tubes used for transporting materials, such as gas, liquid, powder, and granular substance. Further, the structural object can be a vertical hole-shaped reinforced concrete structure, such as a hoistway used as an elevator shaft in which a lift or an elevator travels.

(271) In the above described embodiment, the size of the diagnosis region da11 is set greater than the size of the diagnosis target image dt11 but not limited thereto. For example, the size of the diagnosis region da11 can be set same as the size of the diagnosis target image dt11.

(272) Further, instead of the diagnosis management server 5, the drawing apparatus 3 can be used to create the submission document. In this case, the drawing apparatus 3 can create the submission document (e.g., observed inspection findings chart, photograph ledger, tunnel inspection result summary table), illustrated in FIG. 7, using the data input in step S1 (data transmitted in step S2) and the data received in step S6.

(273) Further, in the above described embodiment, the reception unit 32 receives the drawing of the diagnosis target and the inputting of diagnosis information of the diagnosis target from the user, but not limited thereto. For example, artificial intelligence (AI) program installed on the drawing apparatus 3 or the diagnosis management server 5 can search the diagnosis target region on the development-view image 201, automatically select the diagnosis target, and automatically measure the width of the diagnosis target. Further, the selection of the diagnosis target can be also performed by a selection unit implemented by the artificial intelligence program. Further, the width measurement of the diagnosis target can be performed by a measurement unit implemented by the artificial intelligence program.

(274) In the above described embodiment, the development-view image of the structural object is described, but not limited thereto. For example, in case of planar structural objects, such as walls and fences, the whole image showing the entire structural object can be used instead of the development-view image.

(275) Any one of the above-described operations may be performed in various other ways, for example, in an order different from the one described above.

(276) Numerous additional modifications and variations are possible in light of the above teachings. It is therefore to be understood that, within the scope of the appended claims, the disclosure of this patent specification can be practiced otherwise than as specifically described herein.

(277) Each of the functions of the above-described embodiments can be implemented by one or more processing circuits or circuitry. Processing circuitry includes a programmed processor, as a processor includes circuitry. A processing circuit also includes devices such as an application specific integrated circuit (ASIC), digital signal processor (DSP), field programmable gate array (FPGA), system on a chip (SOC), graphics processing unit (GPU), and conventional circuit components arranged to perform the recited functions.
