摘要
在水库库区工程管理与保护范围划界工作中,使用美国天宝UX5 HP无人机航测,获取数字高程模型DEM和数字正射影像图DOM数据。在此基础上初步提取管理范围界线,然后到实地对上述界线进行检查校正,最终确定出范围界线及拐点坐标。该技术方法可靠,较常规测量方法的效率有所提高。
In the demarcation of the project management and protection scope of reservoir area , the data of DEM and digital orthophoto map DOM were acquired by using the Trimble UX5 HP unmanned aerial vehicle （UAV）.Based on this, the management boundary was extracted , And then to the field of inspection and correction of the line , and ultimately determine the scope of the boundary line and the inflection point coordinates , the technical method is reliable , more efficient than the conventional measurement method is im-proved.
