组合激光雷达系统在输电线路测量中的应用
Application of combined laser radar technology in transmission line measurement
Aiming at the problem of low accuracy and low efficiency of traditional manual measurement methods of transmission line, a combined system in which airborne LiDAR system works collaboratively with terrestrial laser scanner was proposed to measure the transmission line. The airborne LiDAR system is responsible for the acquisition of point cloud data in the transmission line corridor and the terrestrial laser scanner is responsible for the acquisition of high precision point cloud data of the electric tower. By calculating the rotation matrix and translation vector between the two coordinate systems, two sets of point clouds can be merged. The application test was carried out in Zhangbei 500KV high-voltage transmission line project, the results show that the system could effectively and accurately detect the dangerous points in the transmission line corridor and monitor the inclination and deformation of the electric tower, with a certain practical value.
