Problems solved by technology
[0003] At present, for the detection of cement cracks, asphalt longitudinal cracks and transverse cracks, in the face of complex background environments, for example, the texture of the road background and uneven illumination when imaging the road surface, the edge features of the cracks will be greatly covered at this time; Commonly used edge detection methods are generally robust due to the limitation of edge threshold selection. In this way, the results of crack detection deviate greatly from the actual situation, and the accuracy is low.

The present application relates to a pavement crack detection method and device. The method includes: acquiring a pavement image; performing crack segmentation on the pavement image to obtain a plurality of crack area images contained in the pavement image; determining the crack gray level of each crack area image; the crack gray level includes low gray cracks and high gray cracks. identify the crack edge in each crack area image; the crack edge is obtained by processing the crack area image according to the image processing mode corresponding to the crack gray level; according to the crack edge of multiple crack area images, the crack in the pavement image is obtained information. Using this method, the corresponding edge detection can be performed according to the crack gray level of the crack, so the influence of non-crack edges can be effectively reduced, and crack information with better robustness, closer to the actual crack situation and higher accuracy can be obtained .
Description
technical field [0001] The present application relates to the technical field of pavement detection, in particular to a pavement crack detection method and device. Background technique [0002] Pavement damage can be divided into functional attenuation and structural damage. Structural damage will lead to a reduction in the bearing capacity of the pavement structure, which is manifested in the form of various structural cracks, such as cracks, block cracks, longitudinal cracks, and transverse cracks. [0003] At present, for the detection of cement cracks, asphalt longitudinal cracks and transverse cracks, in the face of complex background environments, for example, the texture of the road background and uneven illumination when imaging the road surface, the edge features of the cracks will be greatly covered at this time; Commonly used edge detection methods are generally robust due to the limitation of edge threshold selection, so the results of crack detection deviate gre...
