Key technologies of laser point cloud data processing in power line corridor

Airborne LiDAR can quickly obtain the high precision three-dimensional information of the target object. It can be used for 3D visualization of power line and measuring distance between power line and ground object. In recent years, it has been widely used in the power industry which is one of the most successful industries for the application laser technology. This paper introduces common post-processing technique of point cloud data in the power line corridor, including the point cloud generation, point cloud filtering and power line classification, power line reconstruction, power line safety distance inspection, power lines 3D visualization. This paper provide reference for application of airborne LiDAR power line inspection technology.
