In order to reconstruct ancient architecture accurately and quickly, a hybrid algorithm combining improved marching cubes with deformable model is adopted in the study based on an optimized spatial grid data structure. After preprocessing such as filter, registration, merging and so on, laser scanning data for reconstructing ancient architecture has become discrete points. So an optimized spatial grid data structure is exploited firstly to build topological relationships between points. Then the improved marching cubes are used to build an initial surface model implied by laser scanning data. Finally, an accurate model is got through the coupling effect between the surface model and laser scanning data according to the theory of improved deformable model. Laser scanning data captured from Forbidden City of China is taken as examples to test the method proposed in the literature. Results show the efficiency and robustness of the method addressed in the paper to mode ancient architecture.
