摘要
本文通过使用三维激光扫描仪对天幕钢结构的立柱、横梁与行架进行扫描测量,建立点云模型,获取钢柱中心坐标,并与全站仪测量的结果进行比较,以确定三维激光扫描在工程上能够达到的测量精度,为三维激光扫描仪在钢结构工程竣工验收上的运用做准备。
According to scan and measure the roof of the steel columns,beams and two line by three-dimensional laser scanner measurement,this paper established the point cloud model,get the center coordinates of steel,and compared with the results of total station.Then,this issue defined measurement accuracy of three-dimensional laser scanner measurement in engineering applications,preparing for final acceptance of the steel structure project by Three-dimensional laser scanner measurement.
