Free View Reconstruction of Three-Dimensional Integral Imaging Using Tilted Reconstruction Planes With Locally Nonuniform Magnification

In this paper, we present a method for three-dimensional (3D) free view computational volumetric reconstruction of integral imaging (II) on a tilted reconstruction plane with a locally nonuniform magnification ratio. The reconstruction plane of conventional free view II is parallel to the pickup device. Thus only the part of object parallel to the pickup device can be observed. To overcome this problem, the reconstruction plane could be tilted according to the viewing point by the ldquoOne Point Perspective Technique.rdquo A reconstructed 3D image, using tilted reconstruction planes, can have more in-focus surfaces of the 3D object compared to using parallel reconstruction planes. To verify the proposed method, we generate the elemental images of the 3D object, reconstruct 3D images on both parallel and tilted reconstruction planes, and compare the results.
