基于改进目标检测网络的输电线路舞动检测OA

To detect the phenomenon of transmission line galloping and ensure the stability and reliability of transmis⁃sion network,a transmission line galloping detection method based on an improved object detection network is proposed to detect transmission line galloping.First,the transmission line in the monitoring video is detected by oriented bound⁃ing boxes of the object detection network YOLO11,so that the bounding boxes can better surround the object position.Second,one part of the C3k2 module is replaced by the C3 module which integrates a BiFormer attention mechanism,a simplified spatial pyramid pooling-fast(SPPF)module is used to replace the SPPF module,and a PIoU loss function is introduced to improve the network and enhance its image feature extraction capability and detection accuracy.Finally,the position of the transmission line detected by the bounding boxes is extracted,and the galloping trajectory is drawn.Experimental results show that compared with those of the unimproved network,the precision rate and mean average ac⁃curacy of the improved network are improved by 2.4%and 1.3%,respectively,indicating that the proposed method has better galloping detection effect and detection accuracy.
