The traditional manual inspection method of transmission line has the problems of low efficiency and high expend. Hence, based on the 3D laser radar technology and combined with the unmanned aerial vehicle, this paper designs and develops a set of obstacle detection of transmission line corridor with high automation degree. The system can detect and judge the safety distance between the transmission line and the surrounding obstacles by means of the pre-processing and the classification extraction of the point cloud data, and the threshold comparison of the measured distance. The test and analysis results show that the system can accurately measure and judge the distance between the obstacle and the transmission line, reducing expend of the traditional manual inspection, and providing help for the detection of obstacles in the transmission line corridor.

Key words: 3D laser radar, unmanned aerial vehicle, point cloud, transmission line, obstacle detection
