Highway construction quality automatic detection method and system

The invention relates to the technical field of image processing, in particular to a highway construction quality automatic detection method and system, and the method comprises the steps: collecting a highway image; obtaining a to-be-analyzed image according to the gray values of the pixel points in the road image; according to the gradient values and the gray values of the pixel points in the to-be-analyzed image, obtaining possibility parameters that the edge lines in the to-be-analyzed image are rut edges, and obtaining a plurality of rut edge lines; according to the rut edge lines, the matching degree between the rut edge lines is obtained; fusing all the rut edge lines according to the matching degree among all the rut edge lines to obtain a plurality of complete rut edge lines; and detecting the road quality by using the complete rut edge line. According to the method, all pixel points in an image are analyzed to obtain all track edge lines, and then the track edge lines are fused to obtain a complete
