摘　　要：通过多旋翼无人机低空摄影的硬件的合理配置、飞行线路的合理布置和影像处理软件的合理使用,获取数字正射影像(DOM)和数字表面模型(DSM),提出多旋翼无人机低空摄影技术应用于公路边坡工程测绘的方法。公路边坡工程测绘的实例研究结果表明,(1)DOM成果的长度测量误差为2%,证明DOM可用于公路边坡工程平面图绘制。(2)DSM成果可以直观反映典型截面形状和边坡治理的整体情况,坡度测量误差为1°,证明DSM可用于典型截面的绘制。The mapping method of road-slope based on low-altitude photogrammetry by using multi-rotor UAV is proposed. In this paper,the Digital Orthophoto Map（ DOM） and the Digital Surface Model（ DSM） of a road-slope are obtained based on the proper choosing hardware of UAV,the proper planning of flight routes and the proper using of software for digital image processing. The mapping results of a case study on the road-slope show that,（1） the error in length is 2%,indicating the DOM result can be used in the plan mapping of road-slope;（2） the error in slope is 1°,indicating the DSM results can be used for the mapping of typical road cross-section. In addition,the typical road cross-section and the whole surface of the road-slope can be intuitively displayed by the obtained DSM results.
