3D Modeling of Underground Geological Park Based on Terrestrial Laser Scanner

The main idea of this paper is to describe the application of Terrestrial Laser Scanner in 3D modeling. Considering the special terrain structure of underground geological park, a 3D modeling procedure based on Terrestrial Laser Scanner is designed. The graphs of vertical cross-section and horizontal cross-section are achieved after model optimization. Experiments show that the method can work better than Ground-based measurements in 3D modeling of underground geological park. The 3D model of underground geological park can be used to monitor the amount of mining and get the graphs of vertical cross-section and horizontal cross-section, which will be applied widely in future.
