Tunnel surface deformation analysis method, device and equipment and storage medium

The invention discloses a tunnel surface deformation analysis method, device and equipment and a storage medium, and relates to the field of buildings. The method comprises the following steps: acquiring first point cloud data of a tunnel and second point cloud data of the tunnel; generating a reference curved surface model based on the first point cloud data by adopting an NURBS curved surface modeling technology, and generating a sample curved surface model based on the second point cloud data by adopting the NURBS curved surface modeling technology; determining a reference deformation monitoring point from the reference curved surface model by adopting a rapid reverse solving technology, and determining a sample deformation monitoring point from the sample curved surface model by adopting the rapid reverse solving technology; and solving the difference between the reference deformation monitoring point and the sample deformation monitoring point to obtain the deformation amount of the tunnel. The tunnel de
