Multiple-center-of-projection images
Paul Rademacher, Gary J. Bishop · 1998
In image-based rendering, images acquired from a scene are used to represent the scene itself.A number of reference images are required to fully represent even the simplest scene.This leads to a number of problems during image acquisition and subsequent reconstruction.We present the multiple-center-of-projection image, a single image acquired from multiple locations, which solves many of the problems of working with multiple range images.This work develops and discusses multiple-center-ofprojection images, and explains their advantages over conventional range images for image-based rendering.The contributions include greater flexibility during image acquisition and improved image reconstruction due to greater connectivity information.We discuss the acquisition and rendering of multiple-center-of-projection datasets, and the associated sampling issues.We also discuss the unique epipolar and correspondence properties of this class of image.
