| Abstract: | Remote sensing based on UAV （Unmanned Aerial Vehicle） has more advantages over the traditional methods, such as low cost, high efficiency and remarkable flexibility. In this paper, the composition of UAV remote sensing system was introduced, the work flow and analyze methods were described, such as acquisition of raw images, feature extraction and matching, ortho rectication and mosaicing, generation of DTM （Digital Terrain Model） and DOM （Digital Orthophoto Map）. Experimental results showed that low-altitude UAV remote sensing could meet the needs of the large scale mapping, three dimensional landscape reconstruction, land use survey, and environmental monitoring. |
