The Application Research of UAV-based LiDAR System for Power Line Inspection

摘要

Helicopter-based LiDAR system due to high input cost and personal risk resulting in a certain restrictions on overhead power lines. With the developed application of UAV platform for power lines surveys and miniaturization of LiDAR device, the integration of UAV-based LiDAR system comes to maturity and compensate for the lack of Helicopter platform. Unmanned helicopter based LiDAR system acquire high accuracy 3D point cloud to reconstruct the model of power lines and the dangerous point detection etc. In this article, the UAV-based LiDAR system utilizes the Dragon-50 unmanned helicopter, made in Switzerland, and GL-70 equipment, made in America. This system was used to survey the Shandong Zouchuan power line with 500kV, acquired LiDAR point cloud successfully and met the expectation. The unmanned airborne LiDAR system provides a reference for the promotion of power inspection applications.
