Automatic insulator identification and analysis system

Abstract

The invention discloses an automatic insulator identification and analysis system. The system performs the following steps: performing picture preprocessing, extracting an insulator in a picture, detecting the defects of the insulator, extracting the insulator in the picture by the step of extracting the insulator in the picture after the picture preprocessing is performed on the picture, then the defects in the picture are detected by the step of detecting the defects of the insulator, the picture preprocessing comprises an image collection module and global linear transformation, the global linear transformation is connected with the image collection module and mainly converts the picture into a gray scale map, so that the contrast and the quality of the picture are improved, the insulator in the extracted picture comprises Sobel edge separation, morphological filtering, insulator making and noise point separation, the insulator defect detection comprises texture extraction, classification processing, self-destruction, gap locating and stain detection, pooling work of the insulator is realized, and the operation safety of a power system is ensured.

Description

technical field [0001] The invention belongs to the technical field of electric power inspection, in particular, the invention relates to an automatic identification and analysis system for insulators. Background technique [0002] Insulators on transmission lines are exposed to the field environment for a long time, subject to continuous mechanical tension, electrical flashover, and material aging, and are prone to defects such as insulator self-explosion, cracks, and pollution. With complex terrain, manual inspection is not only difficult, but also highly dangerous. Therefore, drones and other tools with strong environmental adaptability and high degree of automation are used to obtain photos, so that technicians can analyze and judge the condition of insulators through photos. , but the number of photos obtained is huge, and personnel are often required to analyze and judge the pictures, which is a heavy and cumbersome workload.
