| 摘 要： | 为了对隧道的整体变形进行全面监测，采用理论结合实验研究的方法，基于三维激光扫描技术监测隧道变形，利用代数拟合、几何拟合和基于不变矩的椭圆拟合方法，均可对扫描断面拟合，两期拟合断面的差表示了隧道断面的变形，其应用效果良好。

| Abstract: | To comprehensively monitor the overall deformation of a tunnel, theoretical study combined with tests was carried out. Based on 3D laser scanning technology to monitor the tunnel deformation, elliptical fitting method including algebraic fitting, geometric fitting and ellipse fitting based on moment invariants were adopted to fit the scanned cross-section. The difference between two fitting cross-sections indicates deformation of the tunnel cross-section with good results obtained. |
