Power transmission line conductor foreign matter identification method and device

The invention belongs to the field of intelligent operation and inspection of power transmission lines, and particularly relates to a power transmission line conductor foreign matter identification method and device. The method comprises the following steps: firstly, acquiring a power transmission line image shot by a power transmission line monitoring and shooting device, detecting a lead in the power transmission line image by adopting a lead area identification algorithm, and intercepting a lead area; then, respectively inputting the cut lead area image into a Cascade RCNN lead foreign matter identification model and a YOLOV5 lead foreign matter identification model to carry out lead foreign matter identification; and finally, fusing the identification results of the two models, and filtering a coincident frame to obtain a final identification result. The method can accurately identify the transmission line conductor foreign matter, and can be applied to different transmission line scenes. The accuracy and
