摘要
针对农村地区输电线路螺栓锈蚀情况严重且不易检测的问题,提出一种利用深度学习目标检测网络的螺栓锈蚀检测方法,首先自制无人机图像数据集,然后利用二阶微分锐化和暗通道去雾对螺栓图像进行锐化和去雾处理,最后使用YOLOv5网络模型进行数据集的训练与测试,相比其他网络模型检测精度更高,其平均精度均值达93.6%。结果表明,所提方法能够有效实现无人机巡检图像中螺栓部件的识别与锈蚀检测。
Aiming at the problem that the bolt corrosion of transmission line in rural areas is serious and difficult to detect,a bolt corrosion detection method using deep learning target detection network is proposed.Firstly,the UAV image data set is self-made,and then the bolt image is sharpened and defogged by second-order differential sharpening and dark channel defogging,Finally,the yolov5 network model is used to train and test the data set.Compared with other network models,the detection accuracy is higher,and the average accuracy is 93.6%.The results show that the proposed method can effectively realize the recognition and corrosion detection of bolt parts in UAV patrol image.
