摘　　要：在简单地形地貌区域进行无人机航空摄影,使用专业软件进行空三解算,对空三结果出现不合格现象进行分析,通过补测多比例尺航空影像进行联合空三解算,优化空三结果,提高三维模型精度,满足无人机航测在大比例尺地形图测绘中的精度要求。Unmanned aerial vehicle(UAV)is used to take photogrammetry in a simple geomorphology area,and the photos are calculated by professional triangulation software.The unqualified triangulation result is solved by take redundant multi-scale aerial images and calculated by combined triangulation once more.The three-dimensional(3D)model’s accuracy is improved to meet the accuracy requirements in large-scale topographic mapping using UVA photogrammetry model.
