Abstract

This paper presents a complete system for scanning the geometry and surface color of a 3D object and for displaying realistic images of the object from arbitrary viewpoints. A stereo system with active light produces several views of dense range and color data. The data is registered and a surface that approximates the data is constructed. The surface estimate can be fairly coarse, as the appearance of fine detail is recreated by view-dependent texturing of the surface using color images. 1. Introduction Convincing virtual reality environments require realistic object models, but such models are often difficult to construct synthetically. We have built a semi-automatic system that can acquire range data, register it, construct a model that incorporates both geometry and color, and render it from an arbitrary viewpoint. In this paper, we describe the system, emphasizing view-dependent texturing of geometric models. 2. 3D object reconstruction 3D object reconstruction consists of three...
