Multi-projector-type immersive light f ield display

Abstract

A light field three-dimensional (3D) display with multi-projectors and a concave screen is proposed. The system sets the viewing area at the center of the concave screen, making viewers enter the center of the system to watch 3D scene around them. The surrounded 3D scene provides viewers a feast of enhanced immersive experience. The light field principle, rendering algorithm, selection of viewing area and experimental results are discussed in the letter, showing the potential of being an all-around-type immersive 3D display by employing more projectors. © 2014 Chinese Optics Letters.
