摘要：It introduces the methods of deformation monitoring based on 3D laser scanner. The point clouds obtained by multi-period scanning for deformation monitored object are registered. The coordinate system of point cloud is unified. Constraint stability is tested through two methods. The deformation and trends are analyzed according to the variations of coordinates of center point modeled targets and the difference of object model. The comparison of the multi-period models and coordinate depends on the MESH interpolation. The deformation monitoring is effective according to experiments. The methods could be applied in damage estimation, disaster prevention, mining survey, output of coal estimate, etc
