Automatic Modelling of 3D Natural Objects from Multiple Views

Abstract

An algorithm for the fast automatic construction of a 3D model of any real object using images from multiple views is presented. The images are taken from a real object rotating in front of a stationary calibrated CCD TV camera. The presented algorithm generates the object shape in a first step. For that purpose an effective implementation of the method of occluding contours is used to obtain a convex volume model of the object. This model is refined in order to detect shape concavities by using additional depth information from disparity estimation and finally approximated by a triangle mesh. In a second step the texture is estimated from the image sequence and projected onto the surface.
