| 摘 要： | 钢结构在长期荷载及不均匀受力的作用下会产生空间变形，其中扰度是其重要的衡量指标。通常采用全站仪采集钢结构轴线上若干特征点进行分析、计算，由于钢结构特征点难以捕捉，测量存在误差，并且有限的空间离散点难以全面反应钢结构空间变形。本文采用徕卡RTC360三维激光扫描进行钢结构扰度测量；介绍了其作业流程及数据处理方法；利用标靶将各个测站的三维点云拼接成一个整体；采用拟合的方法提取空间特征点及轴线；利用三维点云构建空间模型，并与设计模型进行碰撞分析；可全面地反映钢结构的空间变形情况。

| Abstract: | Under the long-term load and non-uniform force, the steel structure will produce space deformation, among which the disturbance degree is an important measure index. Usually the total station instrument is used to collect some characteristic points on the steel structure axis to analyze and calculate. Because the steel structure characteristic point is difficult to capture, the measurement has the error, and the limited space discrete point is difficult to fully reflect the steel structure spatial deformation. Uses Leica RTC360 3D laser scanning to measure the disturbance of steel structure in the paper. It introduces its operation flow and data processing method. The 3D point cloud of each station is spliced into a whole by using the target, the spatial feature points and axes are extracted by the fitting method, and the spatial model is constructed by using 3D point cloud. |
