摘　　要：倾斜摄影测量是推进传统基础测绘向新型基础测绘迭代发展的重要手段。针对传统倾斜摄影测量使用的5镜头相机价格昂贵、体积大、重量重等特点,提出基于大疆M300 RTK搭载轻小型单镜头相机采集项目范围的倾斜数据的方法。利用野外布设像控点进行空三加密生成正射影像图(digital orthophoto map,DOM)及实景三维模型,结合测区范围内收集的资料,采用内外业一体化成图技术,进行野外调绘补测编辑生成大比例尺1∶500数字地形图,并对成果精度进行分析和评定。结果表明:低成本的单镜头无人机倾斜摄影技术获得的成果符合精度要求,其中,平面中误差为±0.08 m、高程中误差为±0.09 m。该方法降低了地形图外业测绘工作量,缩减了成图的时间,有效地提高了成图的效率,进一步丰富拓展了新型基础测绘建设的方式方法。Tilt photogrammetry is an important means to promote the iterative development of traditional basic surveying and mapping towards the new one.A method based on the DJI M300 RTK equipped with a lightweight single lens camera is proposed to collect tilt data within the project scope,in response to the expensive,bulky,and heavy characteristics of traditional tilt photogrammetry with 5-lens cameras.Using field deployed image control points for spatial triangulation to generate a Digital Orthophoto Map(DOM)and a three-dimensional model of the real scene,combined with data collected within the survey area,using integrated mapping technology for both internal and external work,field mapping and supplementary editing are carried out to generate a large-scale 1∶500 digital topographic map,and the accuracy of the results is analyzed and evaluated.The results show that the low-cost single lens unmanned aerial vehicle oblique photography technology meets the accuracy requirements,with mean square errors of±0.08 m in the plane and±0.09 m in the elevation.By such a method,the workload of field surveying and mapping of topographic maps gets reduced,the mapping time gets shortened,the efficiency of mapping effectively gets improved,and thus the methods of new basic surveying and mapping construction further get enriched and expanded.
