| 摘 要： | 针对高潜水位矿区采煤沉陷地植被密度大、无人机摄影测量难以获取地面点云的问题，从采煤沉陷地地形特征出发，提出了一种基于断面式点云滤波和DEM模型修正的采煤沉陷地DEM构建方法，经分析，精度可达到1：500比例尺地形图要求，可以为采煤沉陷地损毁评价和土地复垦工作开展提供重要依据。

| Abstract: | The mining subsidence in high underground water mining area has high vegetation density, so unmanned aerial vehicle photogrammetry couldn't get the point cloud of the ground.To address this problem,this paper proposes a new DEM establishing method of mining subsidence areas based on the cross-sectional point cloud filtering and the revision of original DEM from the perspective of terrain feature of mining subsidence areas.This new establishing method can meet the precision analysis of 1 : 500 topographic map and can provide important basis for ground damage evaluation and land reclamation. |

| Keywords: | unmanned aerial vehicle mining subsidence digital elevation model point cloud filtering high underground water mining area |
