Table screen 360-degree three-dimensional display using a small array of high-speed projectors

Abstract

We propose a 360-degree three-dimensional display with a table screen, which consists of a small number of high-speed projectors and a rotating screen. Because each high-speed projector is located outside the rotating axis of the screen, multiple projectors can be aligned. The lens shift technique is used to superimpose multiple images generated by all projectors on the rotating screen. The screen has an off-axis lens function such that the rotation of the screen generates numerous viewing points on a circle. The use of multiple projectors enables an increase in the number of colors, an increase in the number of viewing points, and a reduction in the screen rotation speed. We develop an image synthesis technique for the proposed display system. A color display system employing three high-speed projectors is demonstrated.
