Embodiment
[0057] Example: such as Figure 1-Figure 4As shown, an automatic tracking method along the transmission line inspection includes an automatic tracking system along the transmission line inspection, and an automatic tracking system along the transmission line inspection includes a video acquisition module, a wire detection module, and a wire tracking system. module, video segmentation module and storage / transmission module, the tracking method of the tracking system is as follows:
[0058] 1) Video collection: use the video collection module to collect video of the transmission line, that is, manned aircraft or drones use the infrared thermal imager, visible light camera and other loads to carry out video collection;
[0059] 2) Conductor detection: Use the conductor detection module to detect the conductors for the collected video, such as figure 2 shown;
[0060] 3) wire tracing: adopt the wire tracing module to trace the wire detected in step 2);
[0061] 4) video segmen...

The invention discloses an automatic tracking method along the line for electric transmission line routing inspection, and comprises an automatic tracking system along the line for the electric transmission line routing inspection. The system comprises a video collection module, a traverse detection module, a traverse tracking module, a video segmentation module and a storage / transmission moduleand adopts a tracking method of video collection, traverse detection, traverse tracking, pole and tower video segmentation and data storage or transmission to obtain the automatic tracking of the electric transmission line routing inspection. By use of the method, the interference of a background line segment for traverse detection can be effectively reduced so as to favorably adapt to illumination changes and the dynamic regulation of camera focal length in a routing inspection process, segmented storage or transmission drastically improves the efficiency and the accuracy of subsequent defectidentification, and the problems of the interference of a background line segment of a traverse detection process, traverse tracking deviation even failure caused by illumination changes and scale changes in a traverse tracking process and low rate and efficiency of the subsequent defect identification can be solved.
Description
technical field [0001] The invention relates to an automatic tracking method along the transmission line inspection, which belongs to the technical field of transmission line inspection. Background technique [0002] The rapid economic development has put forward higher and higher requirements for power supply, high-voltage transmission lines are constantly being built, and the geographical environment that the lines pass through is becoming more and more complex. Traditional manual inspection of transmission lines takes a long time, is highly dangerous and inefficient. Due to its small size, light weight, convenient transportation, and easy operation, UAVs have made great progress in the inspection of power transmission lines in recent years. During the UAV inspection process, the relative position relationship between the pod and the power transmission line is also dynamic, and it is necessary to manually operate the remote control of the aircraft and the load frequently,...
