In allusion to the problem that the transmission line measurement method of the traditional shoulder-mounted theodolite has low efficiency and precision,an infrastructure management and control system for UAV(unmanned aerial vehi-cle)grid based on laser radar is proposed. The system includes the procedures of flight design,data acquisition,data postpro-cessing and 3D modeling. The UAV and laser radar are used to collect transmission line and tower data. The data preprocessing and postprocessing technologies are used to correct laser radar measurement errors and classified point cloud data to improve measurement accuracy. The generated DOM,DSM files and 3D simulation model are exported to save the measurement data. The simulation results show that the system has a high measurement efficiency and precision and can meet the rapid develop-ment of power grids.%针对传统人工肩扛经纬仪的输电线路测量方法效率和精度较低的问题,提出基于激光雷达的无人机电网基建管控系统.该系统包括飞行设计、数据采集、数据预处理、数据后处理和三维建模等流程.首先,使用无人机和激光雷达采集输电线路与塔杆数据;然后,分别使用数据预处理和后处理技术来修正激光雷达的测量误差以及分类点云数据,以提高测量精度;最后,导出生成的DOM,DSM文件和三维仿真模型以保存测量数据.仿真测试结果表明,该系统具有较高的测量效率及精度,可以满足电网快速发展的需求.
