The components may be combined together to form one entity, or some of the components may be omitted, depending on a way of carrying out the apparatus 100 for providing the top view image of the parking space in some forms of the present disclosure.

(20) The components will be described below in detail. The input device 10 may receive, from a user, an input of a command to display a top view image of the current parking space or an input of a command to display a panorama top view image.

(21) The input device 10 may receive the user's request in various ways such as a touch on a screen, a button input, and the like. The input device 10 may receive a swipe for moving the screen, as the touch on the screen.

(22) The top view image generator 20 may be equipped in a vehicle and may generate a top view image of a parking space using a two-dimensional image of the parking space that is taken by a plurality of cameras. Hereinafter, a detailed configuration of the top view image generator 20 will be described with reference to FIG. 3. However, the top view image generator 20 is not necessarily limited thereto.

(23) FIG. 3 is a view illustrating a detailed configuration of the top view image generator included in the apparatus for providing the top view image of the parking space in some forms of the present disclosure.

(24) As illustrated in FIG. 3, the top view image generator 20 included in the apparatus 100 for providing the top view image of the parking space in some forms of the present disclosure may include a camera 110, a ground feature point detector 120, a first attitude angle estimation device 130, a first rotational transformation device 140, a line detector 150, a second attitude angle estimation device 160, a second rotational transformation device 170, and an image synthesizing device 180.

(25) The camera 110 includes a left camera 112 attached to a lower end of a left side mirror of the vehicle, a right camera 114 attached to a lower end of a right side mirror of the vehicle, a front camera 116 attached to the front of the vehicle, and a rear camera 118 attached to the rear of the vehicle.

(26) The left camera 112 takes an image of the ground on a left side of the vehicle and generates a left image I.sub.left on a frame-by-frame basis, and the right camera 14 takes an image of the ground on a right side of the vehicle and generates a right image I.sub.right on a frame-by-frame basis.

(27) The front camera 116 takes an image of the ground ahead of the vehicle and generates a front image I.sub.front on a frame-by-frame basis, and the rear camera 118 takes an image of the ground behind the vehicle and generates a rear image I.sub.back on a frame-by-frame basis.

(28) The ground feature point detector 120 detects a ground feature point P.sub.ground and a translation vector of the ground feature point P.sub.ground on a frame-by-frame basis from at least one image from which the ground feature point P.sub.ground is detectable, among the left image I.sub.left provided from the left camera 112, the right image I.sub.right provided from the right camera 114, the front image I.sub.front provided from the front camera 116, and the rear image I.sub.back provided from the rear camera 118. Here, the image from which the ground feature point P.sub.ground is detectable may include the left image or the right image.

(29) An optical flow based feature point extraction algorithm, such as the block matching method, the Horn-Schunck algorithm, the Lucas-Kanade algorithm, the Gunnar Farneback's algorithm, or the like, may be used as a method for detecting the ground feature point P.sub.ground and the translation vector of the ground feature point P.sub.ground from the left image or the right image. The algorithms are well-known technologies, and therefore detailed descriptions thereabout will be omitted.

(30) The first attitude angle estimation device 130 estimates first attitude angles of the left camera 112 and the right camera 114, based on the ground feature point P.sub.ground and the translation vector of the ground feature point P.sub.ground that are input from the ground feature point detector 120, and generates a transformation matrix [M.sub.1] that represents the estimated first attitude angles in a matrix form.

(31) The first rotational transformation device 140 generates a first top view image by performing rotational transformation of the left image I.sub.left and the right image I.sub.right, based on the transformation matrix [M.sub.1] that is input from the first attitude angle estimation device 130. Here, the first top view image includes a left top view image TI.sub.LEFT obtained by performing rotational transformation of the left image I.sub.left using the transformation matrix [M.sub.1] and a right top view image TI.sub.right obtained by performing rotational transformation of the right image I.sub.right using the transformation matrix [M.sub.1].

(32) The line detector 150 detects a first parking line P.sub.line1 from the left top view image TI.sub.LEFT and the right top view image TI.sub.RIGHT that are input from the first rotational transformation device 140. Here, the first parking line P.sub.line1 includes a left parking line detected from the left top view image TI.sub.LEFT and a right parking line detected from the right top view image TI.sub.RIGHT.

(33) A line detection algorithm may be used as a method for detecting the left parking line and the right parking line from the left top view image TI.sub.LEFT and the right top view image TI.sub.RIGHT. However, the present disclosure is not characterized by the line detection algorithm, and therefore detailed description thereabout will be omitted. Furthermore, a technology for obtaining not only a line but also line-related information, such as the thickness and direction of the line, through the line detection algorithm is well known, and therefore detailed description thereabout will be omitted.

(34) The line detector 150 detects a second parking line P.sub.line2, which is connected to the first parking line P.sub.line1, from the front image I.sub.front and the rear image I.sub.back that are input from the camera 110. Here, the second parking line P.sub.line2 includes an upper parking line detected from the front image I.sub.front and a lower parking line detected from the rear image I.sub.back.

(35) The second attitude angle estimation device 160 estimates second attitude angles of the front camera 116 and the rear camera 118, based on a correspondence relation between a feature pattern of the first parking line P.sub.line1 and a feature pattern of the second parking line P.sub.line2 that are input from the line detector 150, and generates a transformation matrix [M.sub.2] that represents the estimated second attitude angles in a matrix form.

(36) The second rotational transformation device 170 generates a second top view image by performing rotational transformation of the front image I.sub.front and the rear image I.sub.back using the transformation matrix [M.sub.2] that is input from the second attitude angle estimation device 160. Here, the second top view image includes a front top view image TI.sub.FRONT obtained by performing rotational transformation of the front image I.sub.front using the transformation matrix [M.sub.2] and a rear top view image TI.sub.BACK obtained by performing rotational transformation of the rear image I.sub.back using the transformation matrix [M.sub.2].

(37) The image synthesizing device 180 generates the final top view image by synthesizing the first top view image TI.sub.LEFT and TI.sub.RIGHT input from the first rotational transformation device 140 and the second top view image TI.sub.FRONT and TI.sub.BACK input from the second rotational transformation device 170.

(38) The above-described configuration of the top view image generator 20 is merely illustrative, and the present disclosure is not characterized by the technology for generating the top view image. Accordingly, any well-known technology may be used.

(39) The display 30 displays a top view image of a parking space that is generated by the top view image generator 20. At this time, the top view image of the parking space may further include a warning icon.

(40) The display 30 may display a panorama top view image in which the current top view image and the previous top view image of a parking space are connected.

(41) The display 30 may include at least one of a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFF LCD), an organic light-emitting diode (OLED) display, a flexible display, a three-dimensional (3D) display, and/or an e-ink display.

(42) The storage 40 may store various types of logic, algorithms, and programs that are required in a process of capturing a top view image of a parking space on a path along which the vehicle travels and providing a panorama top view image in which the current top view image and the previous top view image are connected, based on a steering angle depending on the travel of the vehicle.

(43) The storage 40 may store a top view image of a parking space that is captured by the controller 70.

(44) The storage 40 may include at least one type of storage medium among memories of a flash memory type, a hard disk type, a micro type, and a card type (e.g., a secure digital (SD) card or an eXtream digital (XD) card) and memories of a random access memory (RAM) type, a static RAM (SRAM) type, a read-only memory (ROM) type, a programmable ROM (PROM) type, an electrically erasable PROM (EEPROM) type, a magnetic RAM (MRAM) type, a magnetic disk type, and an optical disk type.

(45) The motion detection sensor 50 is mounted on the rear, right, or left side of the vehicle and detects a movement around an empty parking place. That is, the motion detection sensor 50 may detect a vehicle approaching the empty parking place and may detect a vehicle leaving the parking place.

(46) The motion detection sensor 50 may include at least one of an ultrasonic sensor, a rear camera, and/or radar.

(47) The steering angle sensor 60 measures a steering angle depending on travel of the vehicle.

(48) The controller 70 performs overall control to enable the components to normally perform functions thereof. The controller 70 may be implemented in a hardware or software form, or may be implemented in a form in which hardware and software are combined. The controller 70 may preferably be implemented with, but is not limited to, a microprocessor.

(49) The controller 70 may capture a top view image of a parking space on a path along which the vehicle travels and may provide a panorama top view image in which the current top view image and the previous top view image are connected, based on a steering angle depending on the travel of the vehicle. At this time, the controller 70 may operate in conjunction with the parking assistance system of the vehicle to capture the top view image of the parking space on the path along which the vehicle travels.

(50) The controller 70 may control the display 30 to display a top view image of a parking space that is generated by the top view image generator 20. The top view image displayed by the display 30 is a real-time image as illustrated in FIG. 1.

(51) The controller 70 may capture the top view image of the parking space that is displayed by the display 30 and may store the captured image in the storage 40. When the lifetime of the top view image stored in the storage 40 exceeds critical time (e.g., five minutes, ten minutes, or the like) or the vehicle moves a critical distance (e.g., 30 m or 50 m), the controller 70 may determine that there is no validity and may delete the top view image stored in the storage 40. That is, the controller 70 may delete top view images that have been stored for the critical time or more among top view images stored in the storage 40.

(52) The controller 70 may generate a panorama top view image as illustrated in FIG. 4, by sequentially connecting previous top view images stored in the storage 40, based on the current top view image generated in real time by the top view image generator 20.

(53) FIG. 4 is an exemplary view illustrating a panorama top view image generated by the apparatus for providing the top view image of the parking space in some forms of the present disclosure.

(54) In FIG. 4, reference numeral 410 denotes a top view image of a parking space that is provided in real time from the top view image generator 20, and reference numeral 420 denotes the previous top view image captured by the controller 70. Reference numeral 420 represents a state in which a plurality of top view images captured are connected.

(55) The controller 70 may shade the captured previous top view image to increase visibility. For example, the controller 70 may apply 20% shading to an area 421 as a first step and may apply 50% shading to an area 422 as a second step. The number of areas to which shading is applied and the percentage of the shading may be varied depending on a designer's intention. The controller 70 may display the shaded panorama top view image on the navigation map.

(56) Hereinafter, a process in which the controller 70 generates (synthesizes) a panorama top view image will be described in detail with reference to FIGS. 5A and 5B.

(57) FIGS. 5A and 5B are exemplary views illustrating a process of generating a panorama top view image by the apparatus for providing the top view image of the parking space in some forms of the present disclosure.

(58) In FIG. 5A, H.sub.p denotes the current top view image, and H.sub.p-1 denotes the previous top view image. The sizes of the top view images are the same as the size of a screen of the display 30.

(59) The controller 70 may generate a panorama top view image by connecting the previous top view image H.sub.p-1 to the current top view image H.sub.p.

(60) However, although the next top view image H.sub.p-1 is generated after the first top view image H.sub.p-2, the current top view image H.sub.p may overlap the previous top view image H.sub.p-1 as illustrated in FIG. 5B. The first top view image H.sub.p-2 and the next top view image H.sub.p-1 are captured images, and the current top view image H.sub.p is an image provided in real time.

(61) In this case, because the current top view image H.sub.p is a base, a panorama top view image is generated by cutting a portion of the previous top view image H.sub.p-1 that overlaps the current top view image H.sub.p and sequentially connecting the remaining top view image H.sub.p-1 and the first top view image H.sub.p-2 to the current top view image H.sub.p.

(62) The controller 70 may adjust the length of the panorama top view image. That is, the controller 70 may adjust the size of the panorama top view image displayed on the display 30.

(63) The controller 70 may control the display 30 to display the panorama top view image as illustrated in FIG. 6.

(64) FIG. 6 is a view illustrating a state in which the display of the apparatus for providing the top view image of the parking space displays a panorama top view image in some forms of the present disclosure.

(65) As illustrated in FIG. 6, the display 30 displays directions of available parking spaces with arrows on a top view image of a partial parking space to inform a driver of empty parking places that are not displayed, but the display 30 does not display the arrows on a panorama top view image because the empty parking places are displayed on the panorama top view image.

(66) Meanwhile, the controller 70 may additionally generate position information of an empty parking place on a top view image generated by the top view image generator 20.

(67) FIG. 7 is a view illustrating another example of a panorama top view image generated by the apparatus for providing the top view image of the parking space in some forms of the present disclosure.

(68) As illustrated in FIG. 7, the panorama top view image generated by the apparatus for providing the top view image of the parking space in some forms of the present disclosure has a form in which a top view image 710 of a parking space that is provided in real time from the top view image generator 20 and previous top view images 721 and 722 captured by the controller 70 are connected.

(69) The controller 70 may shade the captured previous top view images to increase visibility. For example, the controller 70 may apply 20% shading to the area 721 as a first step and may apply 50% shading to the area 722 as a second step. The number of areas to which shading is applied and the percentage of the shading may be varied depending on the designer's intention. The controller 70 may display the shaded panorama top view image on the navigation map.

(70) Hereinafter, a process in which the controller 70 generates (synthesizes) a panorama top view image will be described in detail with reference to FIG. 8.

(71) FIG. 8 is another exemplary view illustrating a process of generating a panorama top view image by the apparatus for providing the top view image of the parking space in some forms of the present disclosure.

(72) As illustrated in FIG. 8, H.sub.p denotes the current top view image, H.sub.p-1 denotes the previous top view image, and H.sub.p-2 denotes the top view image right before H.sub.p-1. The current top view image overlaps the previous top view image because the vehicle turns to the right.

(73) Accordingly, the controller 70 may generate a panorama top view image by connecting the current top view image H.sub.p and the previous top view images H.sub.p-1 and H.sub.p-2, based on the steering angle measured by the steering angle sensor 60. At this time, the controller 70 may use the panorama image generation technology that is a well-known and common technology.

(74) FIG. 9 is a view illustrating position information of an empty parking place represented by the apparatus for providing the top view image of the parking space in some forms of the present disclosure.

(75) In FIG. 9, xc denotes the longitudinal axis of a vehicle, yc denotes the lateral axis of the vehicle, oc denotes the center of the rear axle of the vehicle as a reference point (0, 0), θ denotes the angle (°) of an empty parking place from the xc axis, and ω denotes a steering angle.

(76) Accordingly, the position coordinates of the empty parking place may be represented by (x, y, θ). In the case where the empty parking place is located on a left side of the vehicle, the position coordinates represent the position of the upper left corner of the empty parking place, and in the case where the empty parking place is located on a right side of the vehicle, the position coordinates represent the position of the upper right corner of the empty parking place. Furthermore, x is the x-coordinate based on the xc-yc axes, and the unit of the distance is centimeter (cm). y is the y-coordinate based on the xc-yc axes, and the unit of the distance is centimeter (cm). For example, when x is 50, it means that the empty parking place is spaced apart from the xc axis by 50 cm.

(77) In addition, based on a movement around an empty parking place that is located on a rear side, a right side, or a left side of the vehicle and detected by the motion detection sensor 50, the controller 70 may control the display 30 to additionally display a warning icon 1001 on the empty parking place in a panorama top view image. At this time, the top view image displayed by the display 30 is as illustrated in FIGS. 10A and 10B.

(78) FIGS. 10A and 10B are views illustrating states in which the display of the apparatus for providing the top view image of the parking space displays a warning icon on a panorama top view image in some forms of the present disclosure.

(79) As illustrated in FIGS. 10A and 10B, the areas represented by P on the panorama top view image are empty parking places, and when a movement is detected around a specific empty parking place, the controller 70 controls the display 30 to display the warning icon 1001 on the specific empty parking place.

(80) The empty parking place having the warning icon 1001 displayed thereon is a space that a driver needs to identify, and before parking in the empty parking place on which the warning icon 1001 is displayed, the driver necessarily has to identify the empty parking place. When a parking path to the empty parking place having the warning icon 1001 displayed thereon is calculated, automatic parking may be performed, and when the parking path is not calculated, manual parking may be performed.

(81) FIG. 11 is a flowchart illustrating a method for providing a top view image of a parking space in some forms of the present disclosure.

(82) The steering angle sensor 60 measures a steering angle depending on travel of a vehicle (1101).

(83) The top view image generator 20 generates a top view image of a parking space depending on the travel of the vehicle (1102).

(84) The display 30 displays the top view image generated by the top view image generator 20 (1103).

(85) The controller 70 captures the top view image displayed by the display 30 (1104).

(86) The controller 70 generates a panorama top view image by connecting the current top view image generated by the top view image generator 20 and the captured previous top view image, based on the steering angle measured by the steering angle sensor 60 (1105). At this time, the controller 70 may apply shading to the captured top view image of the panorama top view image. That is, the controller 70 may divide the captured top view image into a plurality of areas and may differently shade the plurality of areas.

(87) For example, the controller 70 may apply 20% shading to the captured previous top view image as a first step when the steering angle is less than 30 degrees and the distance from the vehicle is less than 10 m, may apply 50% shading to the captured previous top view image as a second step when the steering angle is 30 degrees or more and the distance from the vehicle is more than 10 m and less than 20 m, and may apply 80% shading to the captured previous top view image as a third step when the distance from the vehicle is 20 m or more. At this time, 100% shading represents black by which an object in an image is unable to be identified.

(88) FIG. 12 is a block diagram illustrating a computing system for executing the method for providing the top view image of the parking space in some forms of the present disclosure.

(89) Referring to FIG. 12, the method for providing the top view image of the parking space in some forms of the present disclosure may be implemented through the computing system. The computing system 1000 may include at least one processor 1100, a memory 1300, a user interface input device 1400, a user interface output device 1500, storage 1600, and a network interface 1700, which are connected with each other via a bus 1200.

(90) The processor 1100 may be a central processing unit (CPU) or a semiconductor device that processes instructions stored in the memory 1300 and/or the storage 1600. The memory 1300 and the storage 1600 may include various types of volatile or non-volatile storage media. For example, the memory 1300 may include a ROM (Read Only Memory) 1310 and a RAM (Random Access Memory) 1320.

(91) Thus, the operations of the method or the algorithm described in some forms of the present disclosure may be embodied directly in hardware or a software module executed by the processor 1100, or in a combination thereof. The software module may reside on a storage medium (that is, the memory 1300 and/or the storage 1600) such as a RAM, a flash memory, a ROM, an EPROM, an EEPROM, a register, a hard disk, a removable disk, or a CD-ROM. The exemplary storage medium may be coupled to the processor 1100, and the processor 1100 may read information out of the storage medium and may record information in the storage medium.
