【 摘 要 】

It has become one of the hot research subjects in the computer field that is how to reconstruct the 3D solid model of the part quickly and efficiently based-on its multi-vision image sequence. The space carving method can realize to reconstruct 3D model of parts according to its 2D image information obtained from different angles of view. But the surface of 3D model reconstructed is seriously serrated. To get the better surface of 3D model reconstructed, a surface smoothing method based on Octree was proposed in this paper and it was used to smooth the rough surface of the 3D model reconstructed. It is analyzed that the value of n, which is the number of times a body was divided, how to effect on the surface roughness of the model. The results show that the surface smoothness of 3D model reconstructed can be improved by the method based on Octree proposed. The conclusion can provide theoretical reference for improving the surface smoothness of the model.
