UAV航摄系统在水电工程大比例尺地形图测量中的应用

Application Of UAV Aerial Photography System in Large Scale Topographic Mapping of Hydropower Projects

传统利用全站仪和GNSS野外地形图结合测量的作业模式工作量大、工期长,难以满足水电工程地形图测绘对效率提高的要求。文章以山东潍坊抽水蓄能电站1∶2000地形图测绘项目为依托,概述了无人机航摄系统的主要组成部分,阐述了利用无人机航摄系统进行大比例尺地形图制作的工艺流程和技术方法,分析了基于无人机航摄系统所制作的1∶2000大比例尺地形图测绘精度,结果表明:地形图满足成图精度要求。

The traditional operation mode integrating the total station and GNSS field topographic map for measurement has large workload and long construction cycle,and it is difficult to meet the requirements of the efficiency improvement of the topographic map mapping of hydropower projects.Shandong Weifang Pumped Storage Power Station 1∶2000 topographic map mapping project is adopted as the support in the paper to summarize the main component of the UAV aerial photography system.The processes and technical methods of using UAV aerial photography system for large scale topographic map production are described.1∶2000 large scale topographic map surveying and mapping precision produced based on the UAV aerial photography system is analyzed.The results show that the topographic map meets the mapping accuracy requirements.
