| 摘 要： | 本文介绍了三维激光扫描技术原理,给出边坡监测数据获取与处理的技术流程:首先用基于区域的分割方法对深度图像分割,用标志点匹配法进行点云数据匹配,然后利用滤波方法对点云数据进行简化,最后利用迭代最近点法(ICP算法)进行点云拼接。以某边坡的实际监测数据为例,采用Trimble GX200三维激光扫描仪获取点云数据,RealWork Survey Advanced扫描数据处理软件获得DEM数据。结果表明,采用本文技术可获取边坡的DEM及边坡形态,为边坡变形监测与灾害预报提供基础数据。

| Abstract: | This paper introduced the principle of three-dimensional laser scanning technology,and gave the technical process of data acquisition and processing in slope monitoring: First of all,the depth image was decollated based on the regional segmentation method,and point cloud data was matched by signs point matching method.Then point cloud data could be simplified using filtering method,and finally point cloud was spliced using the iterative closest point method(ICP algorithm).With the actual monitoring data of ... |
