As shown in FIGS. 4-9, when the machine body 10 is activated for harvesting operations, an operation area 100 is formed in front of the machine body 10, and the machine body 10 only performs the harvesting operations in the operation area 100. One of ordinary skill in the art can understand that, the harvesting operations of the machine body 10 sequentially performs operations including cutting, conveying, threshing, storing etc. of crops while moving forward. In other words, the operation area 100 of the machine body 10 includes not only crops being harvested, but also crops that have been harvested and crops to be harvested, and the operation area 100 is moveable.

[0069] The image capturing assembly 20 is installed on the machine body 10 in a covering manner, and acquires images toward the operating area 100. In other words, an acquiring range of the image capturing assembly 20 covers a front and sides of the machine body 10. It is worth mentioning that, the harvested operations have been saved by the machine body 10. The image capturing assembly 20 acquires the images of the operation area 100 including the crops being harvested and the crops to be harvested. Preferably, in the preferred embodiment, the image capturing assembly 20 is installed on the front and both sides of the machine body 10. That is, the image capturing assembly 20 acquires the images of the operation area 100 in a manner around front of the operation area 100.

[0070] It is worth mentioning that, the images acquired by the image capturing assembly 20 basically covers the operating area 100. The images acquired from the image capturing assembly 20 can reflect images around the machine body 10, and after being further processed, the acquired images can express the state information of the operating area 100.

[0071] Preferably, the images acquired by the image capturing assembly 20 may be multiple copies, and the images provided by output of the image capturing assembly 20 are one of the multiple copies. More preferably, the output of the image capturing assembly 20 is the state information of the operation area 100. The state of the machine body 10 in operation is acquired according to the images acquired by the image capturing assembly 20.

[0072] Referring to FIG. 2, the image acquisition device includes the image capturing assembly 20 and a communication device 30, the communication device 30 is communicatively connected with the image capturing assembly 20 and acquires image information from the image capturing assembly 20. The image acquisition device is installed in the machine body 10. When the machine body 10 performs the harvesting operations, the image capturing assembly 20 acquires the images of the operating area 100, and the communication device 30 uploads the information provided by the image capturing assembly 20. Preferably, the communication device 30 transmits a copy of images provided by the image capturing assembly 20 to a remote monitoring terminal to ensure real-time transmission. More preferably, the communication device 30 transmits processed information of the image acquired by the image capturing assembly 20 to a remote control terminal to ensure a transmission speed.

[0073] In the preferred embodiment, the image capturing assembly 20 is distributed on the front and the sides of the machine body 10. The multiple copies of images acquired by the image capturing assembly 20 are spliced, and then transmitted through the communication device 30.

[0074] In detail, as illustrated in FIGS. 2-3, the machine body 10 includes a body frame 11, at least one wheel frame 12, and a harvesting frame 13, the harvesting frame 13 is arranged at a front of the body frame 11, the wheel frame 12 is supported on a bottom of the body frame 11. The wheel frame 12 is operated to drive the harvesting frame 13 and the body frame 11 forward to cut and transport the crops in front. The image acquisition device is arranged on the body frame 11 of the agricultural harvesting operation machine. More specifically, the image capturing assembly 20 is arranged on the body frame 11, and the image capturing assembly 20 acquires the images towards the operating area 100, and avoids acquiring images of the wheel frame 12 and the harvesting frame 13.

[0075] Further, in the preferred embodiment, the image capturing assembly 20 includes a number of acquisition devices and a processor 24. The number of acquisition devices of the image capturing assembly 20 are pre-installed on the front and sides of the body frame 11 in a predetermined orientation. The images acquired by the acquisition devices are processed, summarized, and analyzed by the processor 24. Preferably, the processor 24 performs image processing according to the positions where the acquisition devices are installed.

[0076] In detail, the acquisition devices may be implemented as a number of wide-angle cameras, or may be implemented as a panoramic camera. In the preferred embodiment, The acquisition devices, as illustrated in FIG. 3, are installed in a distributed manner and classified as a distant view acquisition device 21, at least one close view acquisition device 22, and at least one side view acquisition device 23. The distant view acquisition device 21 and the close view acquisition device 22 are adapted to the body frame 11 and forward facing, and face an upper side and a lower side of the harvesting frame 13 respectively. More specifically, the distant view acquisition device 21 acquires images along the upper side of the wheel frame 12, and the close view acquisition device 22 acquires images along positions between the wheel frame 12 and the wheel frame 12. The side view acquisition devices 23 are respectively installed on both sides of the body frame 11, and acquire images of crop state on both sides.

[0077] That is, the images acquired by the distant view acquisition device 21 are related to the state of the crops to be harvested, and the images acquired by the close view acquisition device 22 are related to the crops being harvested. The images acquired by the side view acquisition device 23 are related to the position of the operation area 100.

[0078] Preferably, the distant view acquisition device 21, the close view acquisition device 22, and the side view acquisition device 23 are respectively numbered according to the installed positions. The processor 24 acquires the position of the corresponding acquisition device according to each different number, and processes the images according to the acquired positions of the images. Since the processing is based on a position source of the image, the processing speed is increased. Especially for image splicing processing, based on the installed positions of the distant view acquisition device 21, the close view acquisition device 22, and the side view acquisition device 23, the images around the machine body 10 can be acquired quickly, thereby acquiring the state of the operating area 100. In particular, based on different position types of the distant view acquisition device 21, the close view acquisition device 22, and the side view acquisition device 23, the body frame 11, the wheel frame 12, and the harvesting frame 13 in the acquired images can be omitted by default. For example, a lower edge of the image acquired by the distant view acquisition device 21 may be regarded as the harvesting frame 13, and the lower edge is pre-cut or omitted in the processing process. For example, an upper edge of the image acquired by the close view acquisition device 22 can be regarded as the harvesting frame 13, and a lower edge can be regarded as the wheel frame 12, so as to acquire state information of the crop being harvesting. For example, a lower edge of the image acquired by the side view acquisition device 23 can be regarded as the wheel frame 12, so that part of the machine body 10 can be excluded. Therefore, the images acquired by the distant view acquisition device 21, the close view acquisition device 22, and the side view acquisition device 23 are quickly and preliminarily processed and spliced by the processor 24, to acquire the state information of the operation area 100.

[0079] In detail, an image processing method of the preferred embodiment is shown in FIGS. 4-6. The image processing method for the agricultural harvesting operation machine includes the following steps:

[0080] I. Acquire a number of copies of images of the front and sides of the machine body 10;

[0081] II. Splice the images according to positions in the acquired images; and

[0082] III. Acquire state information around the machine body 10 according to the spliced image.

[0083] In detail, as illustrated in FIG. 5, in the preferred embodiment, a number of the distant view acquisition devices 21 acquires the images toward the upper side of the harvesting frame 13. A number of the distant view acquisition devices 21 are installed at a certain interval, so that the operation area 100 at the front of the machine body 10 is covered. That is, the number of the distant view acquisition devices 21 acquires the images for the crops to be harvested, which is the step I.

[0084] Then, according to the installed positions of the number of distant view acquisition devices 21, the acquired images are sequentially spliced, so that the images of the crops to be harvested in front of the harvesting frame 13 are acquired. It is worth mentioning that, unlike the existing image splicing, there is no need to recognize each image to determine content of the image, but to splice a number of images directly according to the installed positions or the harvesting frame 13 in each image. Thus, an overall image of the front of the machine body 10 is acquired, which is the step II.

[0085] Then in step III, according to the overall image of the front of the machine body 10 acquired by the distant view acquisition device 21, the operating area 100 in front of the machine body 10 is acquired in real time and state information is represented. Preferably, the acquired images can be further analyzed in detail later.

[0086] In detail, as illustrated in FIG. 4, in the preferred embodiment, a number of close view acquisition devices 22 acquires the images between the bottom of the harvesting frame 13 and the wheel frame 12. A number of close view acquisition devices 22 are installed at a certain interval, so that the operation area 100 in the middle of the machine body 10 is covered. That is, a number of close view acquisition devices 22 acquires the images for the crops being harvested, which is step I.

[0087] Then, according to the installed positions of the number of close view acquisition devices 22, the acquired images are sequentially spliced, so that the images of the crops being harvested under the harvesting frame 13 are acquired. It is worth mentioning that, unlike the existing image splicing, there is no need to recognize each image to determine content of the image, but to splice a number of images directly according to the installed positions or the harvesting frame 13 in each image. Thus, an overall image of the working machine body 10 is acquired, which is step II.

[0088] Then, according to the overall image of the working machine body 10 acquired by the close view acquisition devices 22, a harvesting state of the machine body 10 in the operation area 100 is acquired and represented in real time, which is step III. Preferably, the acquired images can be further analyzed in detail later.

[0089] In detail, as illustrated in FIG. 6, in the preferred embodiment, a number of side scene acquisition devices 23 acquire the images toward both sides of the machine body 10. The number of side scene acquisition devices 23 are respectively installed on the left and right sides of the machine body 10, so that the state of the crops on both sides of the machine body 10 can be acquired. That is, generally, the side scene acquisition devices 23 acquire images of a field that has been harvested and a field to be harvested respectively, which is step I.

[0090] Then, according to the installed positions of the number of side scene acquisition devices 23, the acquired images are sequentially spliced, so that the images of the field that has been harvested and the field to be harvested are acquired. It is worth mentioning that, unlike existing image splicing, there is no need to recognize each image to determine content of the image, but to directly acquire the state of the crops that have been harvested according to the installed positions, such as the side view acquisition devices 23 installed on the left side of the machine body 10, and to acquire the state of the crops to be harvested according to the side view acquisition devices 23 installed on the right side of the machine body 10, so as to acquire the state of the crops on the left and right sides of the working machine body 10, the position of the machine body 10 is thus determined, which is step II.

[0091] Then in step III, according to the images of the sides of the machine body 10 acquired by the side view acquisition devices 23, a forward direction and a speed of the machine body 10 can be acquire, thereby ensuring accuracy of the forward direction of harvesting, and helping improve harvesting efficiency.

[0092] Furthermore, the images acquired by the distant view acquisition devices 21, the close view acquisition devices 22, and the side view acquisition devices 23 are finally spliced together, to acquire the image of the machine body 10 in the operation area 100. As illustrated in FIG. 7, the state of the three sides of the machine body 10 is comprehensively acquired. Preferably, the image capturing assembly 20 finally obtains an observation angle similar to that of the machine body 10 from top to bottom, which includes the crops being harvested, the crops to be harvested, and the position of the harvesting operation in the field.

[0093] Further, the image processing method, after step III, further includes the steps:

[0094] Transmit the state information of the machine body 10 remotely.

[0095] As illustrated in FIG. 10, an operation state of the machine body 10 can be acquired remotely. Further, the machine body 10 is remotely controlled for parameters in the harvesting operation. For example, a certain difference between the crops and the harvesting frame 13 is determined according to the images acquired by the close view acquisition devices 22 and the side view acquisition device 23, that is, the operation of the machine body 10 is relatively deviated from a required crop area, the harvesting frame 13 is required to be fully filled, to achieve high-efficiency harvesting. More specifically, for example, 80% of the left side of the harvesting frame 13 is determined to be harvesting crops according to the feedback image, then the state information can be acquired remotely, and the forward direction of the machine body 10 can be adjusted to the left, so that the harvesting frame 13 can fully cover the crops to be harvested.

[0096] Of course, operation adjustments of the machine body 10 can be manually operated remotely, or can be adjusted by a predetermined program, and the images acquired by the image acquisition device can help control so as to realize unmanned agricultural production.

[0097] An image acquisition device for an agricultural harvesting operation machine of another feasible way of the above-mentioned preferred embodiment of the present disclosure is set forth, as illustrated in FIGS. 8-9, the agricultural harvesting operation machine includes a machine body 10A and an image capturing assembly 20A, structures of the machine body 10A and the image capturing assembly 20A are similar with the machine body 10 and the image capturing assembly 20 of the agricultural harvesting operation machine in the above-mentioned preferred embodiment, and is not repeated in the present disclosure.

[0098] The difference from the above-mentioned embodiment is that, FIGS. 4-6 illustrate image splicing according to the same installed positions, and finally three different distant view acquisition devices 21A, close view acquisition device 22A, and side view acquisition devices 23A composite the final image. In the embodiment, according to the positions of the distant view acquisition device 21A, the close view acquisition device 22A, and the side view acquisition device 23A, the images acquired by the acquisition devices with similar positions are preferably spliced, and then subsequently processed to be the final image.

[0099] The images acquired by the distance view acquisition device 21A and the close view acquisition device 22A located at the upper side and the lower side of the harvesting frame 13A are spliced first. As illustrated in FIG. 8, the installed positions of a number of distance view acquisition devices 21A and a number of close view acquisition devices 22A are considered to be adjacent to each other. In other words, the distant view acquisition devices 21A and the close view acquisition devices 22A acquire images of the crops to be harvested and the crops being harvested at the same position relative to the harvesting frame 13A, which is the step I.

[0100] Then, according to the installed positions of the distant view acquisition device 21A and the close view acquisition device 22A located above and below the harvesting frame 13A, the acquired images are sequentially spliced, so that the images of the upper side and the lower side of the harvesting frame 13A are acquired. It is worth mentioning that, unlike the existing image splicing, there is no need to recognition each image to determine content of the image, but directly to acquire an overall image of the crops before and after being cut at a certain position of the machine body 10A according to the installed positions, which is the step II.

[0101] Then in step III, according to an image of a certain position of the machine body 10A, the operation area 100A in front of the machine body 10A is acquired in real time and the state information is represented. Preferably, the acquired images can be further analyzed in detail later, which are similar to a viewing angle of traditional manual cutting.

[0102] In addition, The images acquired by the close view acquisition device 22A located below an end of the harvesting frame 13A and the side view acquisition device 23A located at an edge of the end of the harvesting frame 13A are spliced first. As illustrated in FIG. 9, the installed positions of the side view acquisition devices 23A and a number of close view acquisition devices 22A are considered to be adjacent to each other. That is, the side view acquisition device 23A and the close view acquisition device 22A acquire images of the crops being harvested and the crops that have been harvested located the end of the harvesting frame 13A, which is the step I.

[0103] Then, according to the installed positions of the close view acquisition device 22A located below the end of the harvesting frame 13A and the side view acquisition device 23A located at the edge of the end, the acquired images are sequentially spliced, so that the images of the end of the harvesting frame 13A are acquired. It is worth mentioning that, unlike the existing image splicing, there is no need to recognize each image to determine content of the image, but to directly acquire an overall image of the crops before and after being cut at a certain position of the machine body 10A according to the installed positions, which is the step II.

[0104] Then in step III, according to the overall image of the certain position of the machine body 10A, the operating area 100A in front of the machine body 10A is acquired in real time and the state information is represented. Preferably, the acquired images can be further analyzed in detail later, which are similar to the viewing angle of traditional manual cutting. In the embodiment, an edge working state of the machine body 10A is further acquired, which is convenient for assisting in adjusting the operation position and the operation speed of the machine body 10A.

[0105] It is worth mentioning that, the images acquired by all the acquisition devices, including the distant view acquisition device 21A, the close view acquisition device 22A, and the side view acquisition device 23A, are finally spliced together, so as to acquire an image of the operation area 100A of the machine body 10A. As illustrated in FIG. 7, the state before and after operation of the machine body 10A is comprehensively acquired. Preferably, the image capturing assembly 20A finally acquire an observation angle similar to that of the machine body 10A from top to bottom, including the crops being harvested, the crops to be harvested, and the position of the harvesting operation in the field.

[0106] As illustrated in FIG. 10, the working state of the machine body 10A in the embodiment can be acquired remotely. Further, the machine body 10A is remotely controlled for parameters in the harvesting operation. For example, a certain difference between the crops and the harvesting frame 13 is determined according to the images acquired by the close view acquisition devices 22A and the side view acquisition device 23A, that is, the operation of the machine body 10 is relatively deviated from a required crop area, the harvesting frame 13 is required to be fully filled, to achieve high-efficiency harvesting. More specifically, for example, the crops that are not harvested at the left side of the harvesting frame 13 are determined and displayed in the side view acquisition device 23A according to the feedback image, then the state information can be acquired remotely, and the forward direction of the machine body 10 can be adjusted to the left, so that the harvesting frame 13 can fully cover the crops to be harvested.
