Research on Real-time Tree Barrier Measurement System Based on Three Dimensional Lidar

Abstract

Removing dangerous tree barrier is an important condition to ensure the safe operation of transmission line. A tree barrier measurement technology based on Unmanned Aerial Vehicle (UAV) is proposed in this paper. The technology detects the tree barrier near the transmission line by carrying Three Dimensional (3D) Lidar and on-board computer, de-noises the data obtained during the scanning process, aggregates and classifies the tree barrier data model. Combined with tree barrier measurement algorithm, a real-time tree barrier measurement system and method are formed. Field experiments show that the system can effectively improve the accuracy and efficiency of traverse tree barrier measurement, which is conducive to the realization of information, intelligence and safety of transmission line inspection, and has practical application value for the safe operation of the line.
