In this highly technological world, various methods have been developed for the purpose of recovering the shape of 3D objects from 2D images. In this paper, we introduce methods to combine a collection of range images, which is created by Photometric Stereo, into a single polygonal mesh completely describes an object. Experiments and analysis will be carried out to test the accuracy of our model reconstruction. Finally, results will be displayed. 1 The University of Auckland, Computer Science Department, CITR, Tamaki Campus (Building 731), Glen Innes, Auckland, New Zealand 2 University Hospital Charite, Humboldt University, Berlin, Germany
