Abstract
In view of the difficulty in collecting panoramic information of power grid transmission lines and the inaccuracy of point cloud information processing,a three-dimensional airborne radar point cloud information acquisition system for power grid panoramic transmis-sion lines is proposed.The system realizes the design and selection of airborne radar hardware through the design of airborne radar signal processing system and the selection of acquisition equipment.It uses LiDAR combined with Inertial Measurement Unit to accurately col-lect point cloud data of transmission lines.Using the combination of color information and intensity information in point cloud data,the point cloud data is classified and processed to realize the processing of point cloud data information.The experiment results show that the acquisition error of the system is smaller than that of LiDAR only,and the maximum error is 0.21,and the minimum error is 0.08.The classification accuracy of the system for different objects is different,and the classification accuracy of the transmission line can reach 97％,which is higher than the traditional method and the single point cloud data processing and classification method based on intensity information.关键词
