Abstract

This paper proposes novel Ray-Space acquisition systems that capture dynamic dense Ray-Space in video rate. Most of the previous works on Ray-Space acquisition system targeted “static” Ray-Space because of the difficulty of dealing with dynamic dense Ray-Space. In this paper, we investigate two types of real-time Ray-Space acquisition systems. One uses multiple video cameras. We developed a 16-camera setup and a capturing system using a PC cluster. Interpolation of Ray-Space is introduced to generate dense Ray-Space from sparsely placed video cameras. Another acquisition system captures a “real” dense Ray-Space without interpolation. Using a synchronized galvanometric mirror and a high-speed camera, we succeeded to capture more than 100 view images in 1/30 second. We developed a special hardware that receives digital high-speed camera signal and outputs an arbitrary viewpoint image based on Ray-Space method.
