Accurate detection of grid insulation detection defects is the prerequisite for effective monitoring and fault diagnosis of grid operating conditions.Based on aerial grid insulator image of UAV,in order to solve the problem of false detection and local information loss in deep learning defect detection,an automatic defect detection algorithm based on improved deep learning full convolution network(FCN)is proposed.In the proposed algorithm,the FCN model is improved in the detection of insulator defects by improving the VGG structure,expanding the filter size,eliminating the full connection layer Dropout and the model depth,which realizes the effective improvement of the FCN model in the detection of insulator defects.The experimental results show that,the proposed model improves the performance of the insulator defect detection and the robustness under the less increase of running time,and obtains better detection results than the existing algorithms.
