Automatic Reconstruction of 3D Surface Model with 3D Irregular Points Based on Projection Constrain

Surface model reconstruction from 3D irregular points is of great importance in variable fields such as photogrammetry, 3D reconstruction based on images, scientific computing visualization, etc. 3D points can be obtained with many mature methods such as photogrammetry, laser scanning, etc. While the surface model reconstruction from 3D irregular points is still a difficult problem. In this paper, a novel algorithm based on projective constrain for automatic generation of 3D surface model is proposed. It can make full use of projective constrain of points and make surface reconstruction easy. Experiment results show its reliability.
