| description | The invention provides a building deformation monitoring method based on three-dimensional laser point cloud geometric features. The building deformation monitoring method comprises the steps of three-dimensional laser data acquisition, multi-site cloud registration, single building extraction, building line-plane fitting, line-plane geometric parameter extraction, building deformation analysis and the like. According to the building deformation monitoring method based on features, the defects that in an existing method, the requirement for the precision of a three-dimensional laser scanner is harsh, multi-site cloud registration errors are likely to be introduced, and high-precision control point arrangement is needed can be overcome, point cloud distribution information obtained through three-dimensional laser scanning is fully utilized, the advantages of high precision and high stability brought by fitting of a large number of point clouds can be effectively utilized, the geometric features and change info |
