Abstract

Abstract: In view of the problems of the poor automation, low standardization, long patrol time and frequent crash accidents of the manual-controlled unmanned aerial vehicle (UAV) power line inspection, a multi-rotor UAV intelligent power line inspection method is developed based on RTK positioning technology to realize automatic UAV power line inspection. Under the support of RTK high precision positioning technology, the method is firstly to carry out manual-controlled UAV power line inspection, and then the automatic power line inspection plan is developed according to the recorded patrol track to extract such information as the precise meridian, latitude, altitude and the camera pitch angle of each aerial shooting point. Aerial shooting is carried out at preset angles along the set trajectory control points for automatic patrol, and the flow process and standardization of UAV inspection are realized. The results of field testing show that the proposed method can accomplish the task of the fixed-point patrol inspection quickly and accurately under the environment of strong electromagnetic field, and it lays a foundation for standardized UAV power line inspection.

Key words: transmission line inspection, multi-rotor UAV, RTK positioning, automatic inspection, intelligent inspection, intelligent grid
