Crack measurement method, device and equipment and storage medium
The invention discloses a crack measurement method, device and equipment and a storage medium, and is applied to the field of crack measurement, and the method comprises the steps: constructing a mapping curve set according to pavement images of different illumination parameters under each sight distance parameter; extracting the crack pixel size of the crack image in the crack image data set; calculating a predicted crack size through the crack pixel size and a corresponding mapping curve in the mapping curve set; calculating a mapping precision set according to the predicted fracture size and the actual fracture size; performing deep learning training on the mapping curve set according to constraint conditions set by the mapping precision set to obtain a target mapping curve set; and calling the target mapping curve set to measure the to-be-processed crack image. According to the method, the target mapping curve set of nonlinear illumination is fitted according to the pavement images with different illumination parameters and sight distance parameters, accurate measurement of the crack image is realized, and the problem of large measurement error caused by crack measurement of the pavement image with a single illumination parameter is avoided.
