摘要
手持式移动三维激光扫描仪采用SLAM定位技术,相对于车载或背负式移动扫描仪具有体积小、重量轻、便携等优点,采用ZEB-HORIZON手持移动三维激光扫描仪在地下空间普查中进行应用研究,对某地下车库进行测试,获取了三维激光点云数据,制作切片截取地下车库平面点云,并在CAD里绘制平面图,通过尺寸对比验证其精度。试验结果表明,该仪器获取的点云精度能够满足城市地下空间普查图件的绘制要求。
The hand-held mobile three-dimensional laser scanner adopts the SLAM positioning technology.Compared with the on-board or backpack mobile scanner,it has the advantages of small size,light weight,portability and so on.The application of ZEB-HORIZON handheld mobile three-dimensional laser scanner in underground space survey is studied.A underground garage is tested and three-dimensional laser point cloud data is obtained.The plane point cloud of underground garage is intercepted by using point cloud to make slices,and draw plane graph in CAD.The accuracy is verified by size comparison.The experimental results show that the precision of the point cloud acquired by the instrument can meet the drawing requirements of the urban underground space census.
