The ancient stone arch bridge is the cultural and architectural heritage of human, the protection of it is a worldwide problem. Considering the problems that some ancient stone arch bridges with a long history lack reliable design data, and it is difficult to identify their detailed geometric features efficiently, a novel reconstruction method of ancient stone arch bridge via terrestrial LiDAR scans is proposed in this paper. Firstly, the terrestrial LiDAR w applied to get the whole point clouds of the ancient stone arch bridge surface, and then the point clouds was preprocessed. The non-uniform rational B-spline (NURBS) algorithm is used to extract, fit and reconstruct the ancient stone arch bridge based on the point clouds. The results show that terrestrial LiDAR technology could be used to get point clouds of the stone arch bridge comprehensively and accurately, and realize the reconstruction of the stone arch bridge model.
