Laser point cloud location-based research on patrol inspection of transmission line UAV

In order to realize the autonomous inspection of Unmanned Aerial Vehicle (UAV) on transmission line and reduce the manual flight control operation, this paper proposes a UAV autonomous inspection system based on accurate positioning of laser point cloud. Through the high-precision and three-dimensional laser point cloud data, we can achieve autonomous route planning, independent generation, so as to finally control the whole process of UAV unmanned patrol flight. The testing results show that the UAV based on accurate positioning of laser point cloud has the ability of space collision detection and automatic wall barrier during autonomous inspection flight, which can effectively ensure the flight safety of UAV, reduce the potential risk of power grid, improve transmission line inspection efficiency and operation reliability, and provide a new development direction for follow-up transmission line inspection exploration.
