RTK结合无人机低空摄影在高原地区测绘中的应用

Application of RTK Combined with UAV Photogrammetric in Surveying and Mapping of Plateau

无人机低空摄影是一种新的数字测绘航空摄影技术。探讨了RTK结合无人机低空摄影测量的具体思路,提出了利用模型精化技术提高高程精度的解决方案,结合无人机特点,阐释了无人机低空摄影测量的关键技术。并利用高原地区的试验数据,分析总结了该作业模式的精度和效率。

UAV photogrammetric is a new digital photogrammetric technology. This paper discusses the specific ideas of RTK combined with UAV photogrammetric in surveying and mapping of large scale topographical map, with coming up with the method of height precision using model elaboration. Combined with UAV characteristics, this paper expounds some key technologies of UAV photogrammetric. By experimental data of plateau, we analyzed and summarized the accuracy and efficiency of this homework pattern.
