无人机在河流治理工程中的应用研究

Research on application of UAV in river regulation project

以郁江贵港市宋屋至台岭段治理工程为例,阐述了应用无人机技术提高数字地形测绘效率。根据项目任务特点,结合水利行业规范,分析了无人机的应用过程及其详细技术要求,包括像控点布设、航线规划、飞行技术方案布置及实施、数据采集、外业调绘以及正射影像图(DOM)、数字线划图(DLG)制作等。

Taking the Songwu-to-Tailing section Yujiang River Regulation Project located in Guigang City as example,the authors demonstrate the application of UAV to improve the efficiency of digital terrain surveying and mapping.According to the characteristics of project and combining with the specifications of water conservancy industry,analysis was made on the application process of UAV and the detailed technical requirements,including the layout of image control points,planning of flight route,arrangement and implementation of flight technical scheme,data acquisition,field surveying and mapping,production of DOM and DLG etc.
