Automatic Modelling of 3D Natural Objects from Multiple Views

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 model to obtain natural looking models. Results with real image sequences have confirmed the suitability of the developed algorithm even for the modelling of real objects with highly detailed and complex surfaces. 1 Introduction The objective of this work is the development and refinement of algorith..
