Cable surface defect detection method based on computer vision

The invention relates to the technical field of image data processing, in particular to a cable surface defect detection method based on computer vision, which comprises the following steps: acquiring a cable surface grayscale image; obtaining a plurality of local areas according to an edge detection result of the cable surface gray level image; according to the gray distribution and gradient distribution of the pixel points in the local area, obtaining the representation degree of the local area defect center of each pixel point; obtaining a source point of each local area according to the representation degree of the local area defect center of each pixel point; according to the source points in each local area, obtaining a plurality of source point combinations of the local area, calculating the combination degree of each source point combination, and obtaining the optimal source point combination of each local area; obtaining a plurality of defect areas according to the optimal source point combination of
