为提高云南高山地区航测像控点布设及施测效率,快速高效完成航测任务,结合大型水利工程项目的实施,采用无人机航摄技术对测区1∶2 000库区、隧洞线、引水线路等复杂线路进行航测,提出在大型水利工程实施过程中,通过综合利用、协调配合常规测量与无人机航测成果的方法,使整个项目推进进度达到同等条件下的效率最大化。同时,对实施过程中出现的一些技术问题进行分析、研究。结果表明,该方法能使项目实施效率整体提高。

In the aim of improving the efficiency of a large-scale hydropower construction in the mountain area of Yunnan Province, unmanned aerial vehicle (UAV) was adopted in the aerial photogrammetry survey of reservoir area, tunnel, and diversion route. By integrating and coordinating conventional survey and UAV photogrammetry, the progress of the entire project efficiency under the same condition is maximized. Moreover, some technical problems during the implementation are analyzed. Results indicate that UAV photogrammetry could enhance the efficiency of the entire project.
