Activity tectonic landform three-dimensional model construction method based on laser point cloud data

The invention provides an activity structure landform three-dimensional model construction method based on laser point cloud data. Performing digital modeling by using the laser point cloud data to generate a first model of the activity structure landform; determining a spatial position corresponding to at least one landform structure matched with the landform features of the laser point cloud data to obtain a matching result, and establishing a corresponding deformation model between the laser point cloud data and the first model; determining a non-rigid transformation matrix of the laser point cloud data relative to the first model according to the deformation model; and according to the non-rigid body transformation matrix, generating a three-dimensional model of the activity structure landform, so as to subsequently carry out safety detection on the activity structure landform based on the three-dimensional model of the activity structure landform. According to the application, the monitoring and analysis
