Terrestrial laser scanning (TLS) is gradually applied in tunnel 3D model reconstruction and deformation monitoring. 1) The accuracy of the spatial location of point clouds measured by TLS is essential for tunnel 3D modeling, and the point cloud distribution is a basis for tunnel 3D modeling and designing inspection schemes. However, the characteristics of the point cloud in a tunnel have not been studied clearly. In this paper, a generative model of point cloud distribution is constructed, and a characterization method of point cloud distribution is proposed.
