低空摄影技术在采石区地形测绘中的应用

Application of Low Latitude Photography Techniques in Topographic Surveying and Mapping of Quarry Area

以F1000无人机为航摄平台,对韩城市某采石沉陷区制定了航空摄影测量技术方案。通过控制点布设、影像数据采集、内业数据处理以及产品输出等航测流程,完成了该区域地形图的快速测绘,得到了满足精度要求的区域地形图和正射影像图等,为采石区的生态修复与农业重建提供了直观的基础资料。矿山治理和生态修复等小区域地形航测,拓宽了无人机航测技术的应用范围,具有较强的实践意义。

Taking UAV F1000 as the aerial platform, we made a aerial photogrammetry scheme for a quarry subsidence area in Hancheng City. We completed the topographic map surveying for this quarry area rapidly, through the layout of control point, photographic data acquisition, indoor data processing, output of products and other processes. Then, we obtained the regional topographic map and orthophoto map, which could provide the basic information for ecological restoration and agricultural reconstruction of quarry area directly. At the same time, the topographic and aerial surveying of small area, such as mine management and ecological restoration, can widen the application scope of UAV aerial surveying technology, and it is of an important practical significance.
