Reconstruction Algorithm Based On Photometric Stereo Images Of 3d Models

More recently, as a result of the availability of fast, inexpensive graphics hardware and effective technologies, the reconstruction of 3D models has become one of the most interesting subjects in both computer vision and computer graphics applications. To resolve the problem of 3D reconstruction based on image, this paper presents a new method for 3D reconstruction of models based on photometric technology and get a arithmetic for fairing of surface using this method. The main results in this paper are as following:1. Presents a method for SFS based on model of polyhedron. We carry out the algorithm by solving a overdetermined linear equations which is constructed through the distributing of the vector field. The algorithm can reconstruct 3D surface from photometric stereo image given the direction of illumination.2. Presents a subdivision method to computer the high distinguish ability image within several small pieces.3. Presents a new method for fairing of surface based on smoothing the photometric image of surface. We smooth the photometric image of surface by some existing method in digital image processing, then get an approach to original surface by the photometric stereo technology.4. Give several examples which is got from the computer simulated image of the digital models to show the validity and advantage of the arithmetic in this paper.
