摘　　要：以某水利工程为例,探究了大疆经纬M300无人机低空摄影测量技术在该测区的应用。在基本控制测量与无人机低空摄影测量的基础上,依次对内业数据进行影像纠偏、空三加密、平差解算等处理,同时结合外业调查调绘资料绘制测区地形图。从精度评估情况看,空三加密精度和地形图精度均符合工程需要,为水利工程的建设与维护提供了参考。Taking a certain water conservancy project as an example,this paper explores the application of Low-Altitude Photogrammetry technology using the DJI M300 Unmanned Aerial Vehicle(UAV)in the survey area.On the basis of basic control measurement and UAV low-altitude photogrammetry,image correction,aerial triangula⁃tion,adjustment calculation and other processing are carried out on internal data in sequence,while drawing topo⁃graphic maps of the survey area based on field surveying and mapping data.From the accuracy evaluation,it can be seen that the accuracy of aerial triangulation and topographic map both meet the engineering needs,providing a ref⁃erence for the construction and maintenance of water conservancy projects.
