[0065] Reference Figure 2In this embodiment, in order to facilitate understanding of how to determine the abnormal point area in the target area, an example is given here of how to judge the required maintenance status of any interval section in the target area. Specifically, the method for determining the abnormal point area of ​​each interval section in the target area includes: multiple monitoring feedback points can be set in the target area, and the image information of each interval section in the target area is collected by using the multiple monitoring feedback points; then the image processing analysis is performed on the image information of each interval section in the target area, and then the image feature information of multiple interval sections in the target area is determined (the size of the damaged area, the depth of the damaged area, etc. can be derived by the gray value situation); here, in order to realize automatic and intelligent automatic recognition of the road image of each interval section, the abnormal monitoring information of the target area can be preset according to the road design information of the target area; that is, the abnormal monitoring model is preset according to the normal situation of the road image of each interval section, and then the image feature information of each interval section in the target area can be matched with the abnormal monitoring information of the target area respectively to determine the abnormal information of the target area; finally, the abnormal point area in the target area can be determined according to the route grid information of the target area and combined with the abnormal information of the target area. Specifically, the method for determining the abnormal information of the target area includes: obtaining the image information of any interval road section in the target area, and combining the route grid information of the target area to determine the coordinate area information of the current interval road section; then performing image feature recognition on the image information of the current interval road section to obtain the gray value distribution information of the current interval road section; then marking the gray value abnormal range of the image information of the current interval road section according to the gray value distribution information of the current interval road section to determine the gray value characteristic information in the image of the current interval road section; then setting the abnormal monitoring information in the image of the current interval road section according to the road design information of the current interval road section; finally matching the gray value characteristic information in the image of the current interval road section with the abnormal monitoring information in the image of the current interval road section to determine the abnormal information of the current interval road section. It can be completed that the required maintenance conditions of each interval road section in the target area can be determined through intelligent and automatic image monitoring recognition. Here, in order to facilitate understanding of how to determine the gray value characteristic information in the image of each interval road section according to the gray value characteristic information in the image of the interval road section, the method for determining the gray value characteristic information in the image of the current interval road section includes:

[0066] Assume that there is any abnormal range m in the image information of any section in the target area, then the gray value feature of any abnormal range m is for:

[0069] Reference Figure 3 In this embodiment, since the image length and the actual length in each interval road section image information are proportional, and when there is an abnormal situation in any interval road section image information (such as a broken road surface), the irregular damaged area makes it difficult to determine the damaged area. Here, in order to facilitate the determination of the irregular damaged area, the method for determining the gray value feature information in the current interval road section image also includes: according to the route grid information of the target area, the first contour reference line and the second contour reference line can be simulated and written on any abnormal range in any interval road section image information; then, according to the first contour reference line and the second contour reference line, and in combination with the route grid information of the target area, the intersection coordinate points of the first contour reference line and the second contour reference line with any abnormal range in the current interval road section image information can be determined respectively; and then finally, according to the intersection coordinate points of the first contour reference line and the second contour reference line with any abnormal range in the current interval road section image information, the area of ​​the abnormal range in the current interval road section image information is determined. That is, in this embodiment, the first contour reference line and the second contour reference line can be set in the interval road segment image where the abnormal area exists, and the first contour reference line and the second contour reference line can be respectively used to calculate the maximum horizontal distance and the maximum vertical distance of the irregular damage area using the intersection coordinate calculation method. Furthermore, in order to facilitate understanding of how to determine the irregular abnormal range area in the interval road segment image information, the following example is given here. Figure 3 As shown, the method for determining the abnormal range area in the current section image information includes:

[0070] Suppose any abnormal range in the image information of any section of road is consistent with the first contour reference line Intersects Dot and Point, with the second contour reference line Intersects Dot and point, and the first contour reference line and the second contour reference line Intersects point, then there is an abnormal area in the image information of the current section. for:

[0073] Among them, in order to compensate for the error of calculating the irregular abnormal damage area using the above point coordinates, according to the abnormal area in the interval road section image information, if the intersection area of ​​the first contour reference line and the second contour reference line with the abnormal range is larger than the abnormal area in the interval road section image information, then If the intersection area of ​​the first contour reference line and the second contour reference line with the abnormal range is smaller than the abnormal area in the interval road segment image information, then ,and .
