摘要
介绍了MS50全站扫描仪的技术特点,分析了全站仪模式下直接进行点云拼接的精度,结果表明直接拼接与靶标拼接的精度相当。通过地表监测试验的重复测量精度分析,以及点云滤波、曲面建模等方法对两期点云数据的对比分析,验证了全站扫描仪在地表变形监测中应用的可行性。
This paper introduces the technical indicators and characteristics of MS50 total station scanner,analyzes the accuracy of point cloud stitching directly in the whole station mode,and finds that the direct splicing is equivalent to the target splicing.The feasibility of the application of MS50 total station scanner in surface deformation monitoring is verified by repeated comparison of point of view,point cloud filtering and surface modeling.
