Title:
AUTOMATIC INSPECTION METHOD FOR BELT-TYPE CONVEYING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/134789
Kind Code:
A1
Abstract:
The present invention relates to the technical field of image processing, and relates in particular to an automatic inspection method for a belt-type conveying device, comprising: obtaining suspected defect areas; according to feature distances between adjacent pixel points on edges of each suspected defect area, obtaining edge burr rates corresponding to the suspected defect areas; obtaining a grayscale sequence of edge pixel points and edge peripheral multi-circle pixel points of each suspected defect area; using grayscale values of the pixel points in each grayscale sequence to obtain a mutation degree of the corresponding grayscale sequence; according to the mutation degree of each grayscale sequence and the number of grayscale mutation points, obtaining an expansion degree of the edge pixel points of each suspected defect area; and according to the expansion degree of the edge pixel points of each suspected defect area and the edge burr rate of the corresponding suspected defect area, determining whether the suspected defect area is a real defect area. The present invention increases the accuracy of conveying belt crack inspection.
