摘要
为了有效采集岩溶洞穴内部点云数据,克服单一数据采集手段获取岩溶洞穴内点云数据存在较多数据缺失的问题,通过地面架站式三维激光扫描仪、背包式三维激光扫描仪和摄影测量技术获取岩溶洞穴内的多源点云数据,并采用改进的ICP算法对多源点云数据进行融合。结果表明,采用多种数据采集手段能有效采集岩溶洞穴内的三维点云数据,弥补单一数据采集手段造成的数据缺失,得到较为完整的点云数据。采用改进的ICP算法,可以得到较好的数据融合效果。
In order to effectively collect point cloud data inside karst caves and overcome the problem that a large number of data is missed in obtaining point cloud data inside karst caves by a single data collection method,introduce the result by using the groundmounted 3D laser scanner,backpack 3D laser scanner and photogrammetry technology to obtain multi-source point cloud data in karst caves,which are fused by the improved ICP algorithm then.The results showed that the use of multiple data collection methods can effectively collect three-dimensional point cloud data in karst caves,compensate for the lack of data caused by a single data collection method,and obtain relatively complete point cloud data.By using the improved ICP algorithm,better data fusion effects can be obtained.
