| 摘 要： | 以北京市门头沟区尾矿边坡为例,运用三维激光扫描技术对尾矿边坡进行研究。通过对不同时段采集的点云数据处理,形成相应时段尾矿边坡三维模型。采用等高线比较、三维质检软件比较,提取出边坡变形数据。三维激光扫描技术使滑坡体测绘从传统的GPS或者全站仪单点数据采集变成连续密集的自动获取海量点云数据,增加了测绘信息量。三维激光扫描技术不仅提高测量精度和数据采集速度,且使工作效率实现大幅度的提高。

| Abstract: | This paper takes the tailings slope of Mentougou District of Beijing City as an example ,and studies the tailing slope by using 3D laser scanning technology .By processing the point cloud data of different time ,the 3D model of the tailings slope is formed .The deformation data of the slope is extracted by comparison of the contour and 3D quality software.3D laser scanning technology makes the landslide mapping turn from the single point data of traditional GPS or total station instrument data acquisition into automatic acquisition of intensive data ,w hich can increase the amounts of information in surveying and mapping .The 3D laser scanning technology not only improves the precision and speed ,also the work efficiency is greatly improved . |
