摘　　要：输电线路走廊环境复杂,定高的无人机飞行方式不仅存在一定安全隐患,而且无法满足测绘成果精度要求。结合自行研制内、外业航测软件,利用无人机机载激光雷达设备实施仿地飞行,可以获取高精度输电线走廊精细化的三维模型、数字高程模型以及数字正射影像成果,同时极大地提高电力勘测平断面测量、塔基地形图绘制的生产效率。The environment of the transmission line corridor is complex and the terrain undulates greatly.The traditional fixed-altitude unmanned aerial vehicle(UAV)flight has potential safety hazards,and the accuracy of the surveying and mapping results cannot meet the requirements.By using UAV to carry airborne laser radar equipment and Fly Smart Travel software to implement the new strategy of ground-like flight,it can achieve the acquisition of high-precision transmission line corridor refined three-dimensional(3D)model,digital elevation model and digital orthophoto results,and greatly improve the production efficiency of electric power survey plane section survey and tower base topographic map drawing.
