Application of LiDAR technology in power line inspection

Airborne Light Detection and Ranging (LiDAR) technology brought a new reformation for measurement technology, and the airborne LiDAR technology provides a new way for power line inspection. Compared with the traditional measurement system, airborne LiDAR measurement system has its unique technical advantages, which can directly obtain the power line corridor point cloud and get the high precision of 3D spatial information, then obtain the whole information of the 3D power lines corridor. Relative to the high input cost and high risk of helicopter LiDAR in power line inspection, UAV LiDAR technology has been a great success, which promote the development of the UAV's LiDAR integration technology. The UAV obtain high-precision 3D point cloud data which is equipped with LiDAR system, and then carry out line model reconstruction and hazard detection. The application of LiDAR technology in power line inspection is greatly promoted. (paper)
