Paper Abstract

With the development of Terrestrial 3D Laser-scanning technology, as the one of main methods of earth observing architecture, Terrestrial 3D Laser-scanning technology is increasingly widely applied in the field of ancient architecture protection. Triangulating a set of scattered 3D points is a common approach but a difficult problem to surface reconstruction from unorganized point clouds. Because the amount of point cloud data of ancient architecture is very large and the surface of ancient architecture is very complex comparing to reverse engineering field, Universal triangulation algorithms are inefficient and ineffective for complex surface. On the basis of full analysis of the characteristics of the ancient buildings, a modified surface projection-based triangulation algorithm was proposed in this article, which integrated with the subdivision of the grid by K-D tree and tangent plane projection triangulation. The algorithm was used in a real project. Experiments show that the method is more efficient and effective and support for the 3D model reconstruction of ancient buildings is provided.
