Abstract
An important computer vision task is modeling of 3D objects for computer graphics and animation. This paper presents a method for generating a 3D wireframe model automatically out of a number of views of the original object. The silhouettes of the objects are used to determine the intersecting volume which represents a rough estimation of the object shape in voxel representation. A triangulation algorithm converts the model into a wire-frame surface representation to enhance the quality of the models surface and allow tex-ture mapping. A shape from motion/stereo algorithm is used to enhance the model shape. Calibrated cameras are used to obtain true dimensions.© (1989) COPYRIGHT SPIE--The International Society for Optical Engineering. Downloading of the abstract is permitted for personal use only.
