On the basis of analyzing the domestic development and current situation of UAV inspection on transmission line, a UAV inspection method for transmission line based on 3D laser scanning system was proposed, combined with the current UAV inspection method and its disadvantages, which used laser system, GPS, aerial measurement platform, IMU/INS and digital camera to scan the pole tower in all directions. Then the ground station operates instructions accurately through the system. A fast and effective method for UAV inspection in transmission line was realized. Meanwhile, the research, which overcomed the difficulties by manual inspection to find fault points and fault causes, could be applied to line fault inspection to ensure the safe operation of transmission line.
