Description
technical field [0001] A detection method for insulator damage, which is suitable for insulator damage detection of electrical lines. Background technique [0002] As an important part of electrical transmission lines, insulators play an important role in the erection of electrical lines and are used in large quantities; due to the aging of sheds, mechanical fractures and other reasons, composite insulators often have many defects, and the existence of these defects will greatly It will reduce the electrical performance of composite insulators, and eventually lead to major accidents such as pollution flashover. [0003] One of the existing technologies is the insulator identification method based on ellipse detection. They detect the ellipse in the image through Hough transform, and then obtain the area where the insulator is located according to the side-by-side characteristics of the insulator disks. However, during the imaging process of the insulator, due to the mutual ...
