为了提高对山区城市测量的工作效率，研究了无人机基于倾斜摄影测量对山区城市进行精度分析，概述了倾斜摄影测量和RTK测量两种基本方法，对于数据平差原理进行了相应的公式解析，并对该项目需要用到的设备做了相应概述。解析了无人机倾斜摄影测量的作业流程，主要包括了测量的外业操作流程和内业数据处理流程，运用模型提取坐标与实坐标进行数据对比，得出精度达到厘米级并且满足《低空数字航空摄影规范》(CH/Z 3005-2010)，在山区城市地形图测绘中采用无人机倾斜摄影测量是较好的选择。
In order to improve the efficiency of mountain city surveying, the accuracy analysis of mountain cities based on oblique photogrammetry by UAV is studied, the two basic methods of oblique photogrammetry and RTK measurement are summarized, the corresponding formula analysis of the data adjustment principle is carried out, and the equipment required for the project is relevant summarized. The operation process of UAV oblique photogrammetry is analyzed, mainly including the field operation process and internal data processing process of surveying, and the model is used to extract coordinates and real coordinates for data comparison, and the accuracy reaches the centimeter-level and meets the “Low Altitude Digital Aerial Photography Specification” (CH/Z 3005-2010), which is a better choice for UAV oblique photogrammetry in mountainous urban topographic map mapping.
