Unmanned aerial vehicle inspection method and system for defective insulator

The invention relates to an unmanned aerial vehicle inspection method and system for a defective insulator, and the method comprises the steps: obtaining an insulator image through unmanned aerial vehicle inspection, carrying out the segmentation and recognition of the image, recognizing whether an insulator exists in the image or not, and finally achieving the detection of an insulator fault through structural features. Based on the insulator image, the GPS coordinate positioning information and the analysis result obtained by the unmanned aerial vehicle, the information is displayed throughthe upper computer management operation platform, automatic identification can be completed, and maintainers can visually analyze the geographic position of the defective insulator so as to facilitatetroubleshooting. The insulator defect identification algorithm based on the Faster R-CNN has a rapid insulator defect feature extraction capability, and relatively high discrimination accuracy is achieved through a deep train
