The function of the multi-rotor UAV automatic driving intelligent inspection system is mainly to realize the automatic driving of the UAV under the premise of ensuring the safety of the transmission line and the safety of the UAV, carry out the fine inspection of the transmission line, and intelligently analyze the operation data, and finally Form a job report. According to the high-precision tower coordinates and height information collected in the early stage, the intelligent terminal of the system can automatically plan the optimal UAV laser modeling flight route, and control the lidar UAV to realize the lidar automatic flight. Upload high-precision laser point cloud data to the aircraft patrol operation platform. The platform automatically plans the drone's refined inspection autopilot route based on intelligent algorithms, and feeds the route feedback to the smart terminal, and then the RTK drone can be controlled for real and automated driving flight. Patrol operations. Upload job data to the machine patrol operation platform. The platform uses artificial intelligence image recognition algorithms to identify and extract job photos, classify defects, rename, and archive, and generate job reports. Transmission line multi-rotor UAV automatic driving intelligent inspection system is mainly composed of three parts, namely intelligent terminal, flight platform and aircraft inspection platform. Among them, the intelligent terminal receives the automatic flight route information sent by the patrol operation platform to realize the intelligent control of the flight platform UAV, and at the same time transmits the operation data to the aircraft patrol operation platform for analysis and processing. The flight platform completes the collection of various operation data and transmits the data to the intelligent terminal and the aircraft patrol operation platform. The machine patrol operation platform plans the autopilot route according to the operation data, and performs post-photo processing.
