Abstract: With the development of laser radar technology,LiDAR can be used for power inspections.The traditional patrol method is not high in spatial positioning accuracy,and it is difficult to accurately determine the distance from the ground to the line of the corridor and can not be quickly classified. The rapid development of drone technology also provides a convenient and efficient carrier platform for laser measurement.UAV laser measurement system can better solve these problems and comprehensively obtain data information such as transmission line body,corridor,and equipment operation status.Establish a management system with the functions of transmission,storage,and display of information to realize real-time,comprehensive,and efficient 3D visualization management of transmission lines.

Key words: UAV, airborne laser, electricity, point cloud, classification
