基于地面三维激光扫描技术的跨河建筑物测量分析

Measurement and Analysis of Cross-river Buildings Based on Ground 3D Laser Scanning Technology

该文主要在阐述三维激光扫描技术测量原理的基础上,提出地面三维激光扫描技术在跨河建筑物中的测量情况,以某内河桥梁测量为例,对单站点云配准后的坐标进行转换,从而获取相应的目标点云成果,可以将多个检查点的点云坐标与RTK坐标经过对比分析来验证此研究方法的应用价值和测量精度。经研究发现,基于地面三维激光扫描技术的测量成果点位精度可达6 cm,能够满足跨河建筑物建模基本续期,可以为此技术在市政及其他方面的测量提供良好的借鉴。

Based on the measurement principle of 3D laser scanning technology,this paper mainly puts forward the measurement of ground 3D laser scanning technology in cross-river buildings.Taking the measurement of an inland river bridge as an example,the coordinates of single site cloud registration are converted to obtain the corresponding target point cloud results.The application value and measurement accuracy of this research method can be verified by comparing the point cloud coordinates of multiple checkpoints with RTK coordinates.The research results show that the point accuracy of the measurement results based on the ground 3D laser scanning technology can reach cm,which can meet the basic renewal of cross-river building modeling,and can provide a good reference for the measurement of this technology in municipal and other aspects.
