| 摘 要： | 山体滑坡是不可逆转的自然灾害,实时监测滑坡绝对位移和相对位移,掌握滑坡形变的规律和趋势,可减少经济损失,保障经济发展。三维激光扫描技术是监测山体滑坡的主要方法之一,其关键是去除地表植被、建筑物等其他地物点云信息对地表模型的干扰,获得扫描区域高精度的DEM,进而得到准确的监测信息。因此本文重点分析并去除滑坡体各种干扰地物点云信息。

| Abstract: | landslide is a natural disaster, we can reduce the economy loss and ensure the economic development by monito ring absolute displacement and relative displacement of landslide. 3D laser scanning technology is one of the main methods to monitor landslide. The key is to remove the interference to surface model from vegetation and building. Then get highprecision DEM of The scanning area. Last, get monitor information. So this paper mainly analysis and remove the point cloud information of interferential feature. |
