Transmission line corridor clearance management plays a critically important role in power line risk management and is an important task of the routine power line inspection of the grid company. 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. This study proposes an extraction method of critical areas from power lines using LIDAR point cloud data. The corridor monitoring mainly includes the inspection of the overhanging trees in the corridor and the existence of the bird's nest and other routes, this study, introduce the working principle and application of LIDAR system in power line inspection. LIDAR system's advantage is that can accurately restore the 3D spatial information of line corridors, and then we can get along the more accurate and more comprehensive information of the line and route area.
