In the first, this paper introduces the software and hardware equipment of acquiring 3D laser point cloud data by using UAV equipped with 3D laser scanner, and describes the specific process of acquiring 3D laser point cloud data by using UAV in detail, and the key technology and process of laser point cloud data processing in the room. Then, combined with the specific line engineering, the 3D laser point cloud data of the whole line is acquired by using UAV equipped with 3D laser scanner. By comparing the 3D coordinates of feature points measured by GPS and total station with those corresponding points in the point cloud, the planimetric accuracy and vertical accuracy of 3D laser point cloud data are calculated. It is proved that the accuracy of 3D laser point cloud data can meet the requirements of electric power transmission line planning and design, so the application of UAV airborne 3D laser point cloud data in power planning and design is feasible.
