Problems solved by technology
[0003] The above technical solution needs to obtain the transformation relationship from the pixel coordinates of the diseased area to the world coordinates. The existing technical solution is to use the conversion relationship corresponding to the road surface image as the conversion relationship of the diseased area. However, this will make the calculation error of the diseased area larger.

The invention relates to a road disease area calculation method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring a diseased pavement image carrying a diseased pavement; the disease pavement image comprises a plurality of image areas; acquiring a disease area image corresponding to a disease area of the disease pavement from the disease pavement image, and acquiring a target image area corresponding to the disease area image from the plurality of image areas; obtaining the area of the disease region based on a pre-obtained coordinate conversion relation corresponding to the target image region and the coordinates of the pixel points on the disease region image; wherein the coordinate conversion relation corresponding to the target image area is a conversion relation between the coordinates of the pixel points in the target image area and the coordinates of the position points, corresponding to the diseased road surface, of the pixel points in the target image area. By adopting the method, the area of the road disease area can be accurately calculated.
Description
technical field [0001] The present application relates to the technical field of road disease detection, and in particular, to a method, device, computer equipment and storage medium for calculating the area of road disease. Background technique [0002] With the development of road disease detection technology, a road disease area calculation technology has emerged. This technology first converts the pixel coordinates of the disease area on the image into the world coordinates of the disease area, and then calculates the disease area through the above world coordinates. area of the area. [0003] The above technical solution needs to obtain the conversion relationship from the pixel coordinates of the diseased area to the world coordinates. The existing technical solution is to use the conversion relationship corresponding to the road surface image as the conversion relationship of the diseased area. However, this will make the area calculation error of the diseased are...
