In this paper, we propose a novel approach to reconstruct the perspective-variant three-dimensional (3-D) objects along the depth direction with virtually generated elemental image arrays (V-EIAs) by ray-based pixel mapping in integral-imaging. In the proposed method, V-EIAs having different perspectives of a 3-D object are generated from the originally picked-up EIA (O-EIA) on a specific depth point by virtually moving the pinhole array back and forth along the depth direction of the 3-D object, and mapping each pixel of the O-EIA on to the corresponding positions of the V-EIAs based on ray-optics. With these V-EIAs, perspective-variant 3-D objects are finally reconstructed along the depth direction of the 3-D object. To confirm the feasibility of the proposed method, experiments with test 3-D objects are performed and the results are discussed.
