Abstract

Abstract: Massive point cloud data can build 3D modeling of cultural relics very well. For complex surface structure of cultural relics, traditional algorithms are difficult to achieve fine modeling. In order to solve the problem of spatial triangular mesh, the paper combines the normal vector of spatial triangle to construct triangular mesh. Take Kunming cultural relic——Buddhist stone pilar as an example to carry on the three-dimensional reconstruction, the new method in this paper is suitable for 3D modeling of indoor cultural relics and can achieve better results.

Key words: point cloud data, 3D modeling, spatial triangulation, curvature
