Abstract

A triple-view three-dimensional (3-D) display system based on direct-projection integral imaging is proposed. In the proposed system, which is simply composed of a projector and a convex-mirror array (CMA), three kinds of 3-D object images can be simultaneously displayed on the three spatially-separated viewing zones from the single display screen. Three kinds of elemental image arrays (EIAs) are picked up from each of the 3-D objects, and those EIAs are multiplexed into a single EIA, which is called a multiplexed EIA (M-EIA), using a pixel-mapping method. Then, the divergent beam coming from a projector reads this M-EIA and directly projected onto the CMA. On the CMA, three-view components of the M-EIA are separated and reflected into their own viewing directions, and three different 3-D object images are finally displayed on their viewing zones. Experiments with test objects confirm the feasibility of the proposed system in the practical applications.
