Research Abstract

Ray capture is one of the key technologies for next generation 3D visual communication. "All-around dense ray capture" and "high-efficiency ray capture" are studied to develop a novel principle of ray capture as alternative to multi-camera ray capture. As for all-around dense ray capture, size-reduced ray capture with less distortion is realized by slanted ellipsoidal mirror system. Radon transform and integral transform along sinusoidal waves are developed for efficient ray capture.
