Abstract
An analysis and comparison of the lateral and the depth resolution in the reconstruction of 3D scenes from images obtained either with a classical two view stereoscopic camera or with an Integral Imaging (InI) pickup setup is presented. Since the two above systems belong to the general class of multiview imaging systems, the best analytical tool for the calculation of lateral and depth resolution is the ray-space formalism, and the classical tools of Fourier information processing. We demonstrate that InI is the optimum system to sampling the spatio-angular information contained in a 3D scene.
