In order to meet the requirements of more complex transmission line inspection and improve the real-time perfor-mance of inspection,an improved algorithm model of Faster R-CNN insulator target detection is proposed.A wavelet transform fu-sion wiener filter method is proposed for denoising the patrol insulator images.According to the shape and characteristics of insula-tors,the original anchor frame ratios of 1∶1,1∶2 and 2∶1 are changed to 1∶2,2∶1,1∶3 and 3∶1,which are more suitable for the re-search data,and the softening non-maximum suppression algorithm is used to replace the original non-maximum suppression algo-rithm to solve the problem of insulator occlusion missing due to the shooting angle.Experimental results show that the improved Fast-er R-CNN target detection algorithm has higher recognition accuracy than the original algorithm.
