Realization of Undistorted and Orthoscopic Integral Imaging Without Black Zone in Real and Virtual Fields

Abstract

When integral imaging systems work in their conventional configuration, the reconstructed images are pseudoscopic. The two-step pickup process is capable of giving an orthoscopic image, but it involves black zones, which affect the viewing angle. We analyze the black zones on the elemental images. The improved two-step pickup process is proposed to solve this problem, and the mathematical models of the improved digital secondary pickup process without black zones are also proposed. The simulation and experiment are presented. An undistorted and orthoscopic 3-D scene without black zones is reconstructed in real and virtual fields simultaneously.
