Generation of 360-degree color three-dimensional images using a small array of high-speed projectors to provide multiple vertical viewpoints

The generation of full-parallax and 360-degree three-dimensional (3D) images on a table screen is proposed. The proposed system comprises a small array of high-speed projectors and a rotating screen. Because the screen has a lens function, a large number of viewpoints are generated on a circle when the screen rotates. Thus, 360-degree 3D images having horizontal parallax are generated. Because all projectors are located at different heights from the screen, they generate the viewpoints on a circle at different heights. Therefore, plural viewpoints are aligned in the vertical direction to provide vertical parallax. A prototype display system that employs three high-speed color projectors is constructed.
