[Paper] A 3-D Display Pipeline: Capture, Factorize, and Display the Light Field of a Real 3-D Scene

抄録

Inspired by pioneering work on modern light field displays, we developed a prototype display in which three liquid crystal display (LCD) panels are stacked in front of a backlight. The stacked LCD panels constitute a set of semi-transparent layers, which modulate the out-going light rays. Even though only three layers are used, this display can emit a light field, i.e., a dense set of many multi-view images, in different viewing directions simultaneously. We established a process pipeline from capture to display of the light field of a real 3-D scene. We analyzed the amount of pop-out and motion parallax that can be presented by the display using a given light field data. We used a light field camera (Lytro Illum) and a multi-view camera (ViewPLUS ProFUSIOIN 25) to capture the light field, which was then factorized into layer representations to be displayed. We show several successful results using our prototype display.
