无人机低空遥感作为一种新兴的航空摄影手段，近年来应用越来越广泛。在高原山区测绘大比例尺DEM往往难度较大，本文通过研究，提出利用无人机低空摄影获取数码影像，外业采用GPS测量少量控制点，内业采用多视影像匹配技术自动构建空中三角测量网，然后通过光束法平差实现快速解算，最后生成大比例尺DEM 成果，实践证明是可行的。

UAV low-altitude remote sensing as a new aerial photography means is used more and more widely in recent years .As we all known, it is usually difficult to obtain large -scale DEM in the mountain plateau .In this paper, we propose a new way that uses UAV to obtain high resolution digital images and uses GPS to get a small amount of control points in the field , indoors builds aerial tri-angulation network automatically with the multi -image matching techniques , then through the bundle adjustment to realize a fast solu-tion, finally edits and generates large -scale DEM.It is proved feasible in the practice .
