Abstract

The invention discloses an infrared detection method for insulator defects, which relates to the technical field of infrared identification of insulator defects; it includes the steps of S1 image preprocessing, S2 insulator segmentation and S3 insulator fault detection. In the step S1 image preprocessing, the collected The aerial image of the insulator is gray-scaled and the gray-scaled image is obtained. According to the gray-scale law of the gray-scaled image, the gray-scaled image is segmented and linearly stretched to obtain the gray-scaled stretched image. The gray-scaled stretched image The image is filtered and processed to obtain a preprocessed image; through the steps of S1 image preprocessing, S2 insulator segmentation and S3 insulator fault detection, the identification of insulator defects is realized.

Description

technical field [0001] The invention relates to the technical field of infrared identification of insulator defects, in particular to an infrared detection method for insulator defects. Background technique [0002] With the advancement of smart grid construction, the requirements for intelligent inspection of transmission lines are getting higher and higher. The use of inspection robots and drones based on image recognition technology has gradually replaced cumbersome manual inspections and expensive helicopter inspections. become an inevitable trend. Insulators are the most common components in transmission lines. Once a fault occurs, it will cause contact between transmission lines or between transmission lines and towers, resulting in interruption of power supply, and even large-scale power outages in severe cases. Due to being exposed to the wild for a long time and often being eroded by harsh environments such as storms, rain, and snow, insulators will inevitably expe...
