Method of generating orthoscopic elemental image array from sparse camera array

We propose a method of generating orthoscopic elemental image array from a sparse camera array. A parallax image array obtained by a sparse camera array provides different perspectives of a real three-dimensional (3D) scene, and has all the information the elemental image array needs. In-depth analysis of the generation method and the relationships between the sparse camera array and the elemental image array are presented. The experimental results demonstrate the correctness of the proposed method.
