Problems solved by technology

[0003] In recent years, the method of fault detection of distribution network insulators mainly adopts the method of UAV inspection, but the background of the photos taken by UAV is relatively complex, and the traditional method of manually extracting features to identify insulator faults is easily affected by the background As a result, the obtained features cannot describe the state of the insulator well, so that the identification efficiency of insulator faults is relatively low

Abstract

The invention discloses an insulator fault identification method and device based on a feature pyramid. The method comprises the steps of obtaining a background image containing an insulator; and inputting the background image into a preset insulator fault recognition model, carrying out insulator fault recognition on the background image, and recognizing the faulted insulator in the background image. According to the method, the fault of the insulator can be quickly and effectively identified by constructing the preset insulator fault identification model, the fault identification efficiencyis improved, and the stable operation of a power system is ensured.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a method and device for identifying an insulator fault based on a feature pyramid. Background technique [0002] As one of the main components of power equipment, insulators often fail due to factors such as electric field, harsh weather (dust, ice, snow, lightning) and their own gravity during work. If the corresponding treatment is not carried out in time, it may threaten the entire power system. Safe and stable operation. Therefore, timely and accurate detection of insulator images is of great significance. Insulator image detection can prevent insulators from malfunctioning during operation, reduce unnecessary losses caused by sudden accidents and losses caused by downtime maintenance and overhaul, and insulator image detection has important value for insulator fault diagnosis and maintenance in the later stage. Help relevant personnel quickly and accurately locat...
