Abstract
Full-parallax light-field is captured by a small-scale 3D image scanning
system and applied to holographic display. A vertical camera array is scanned
horizontally to capture full-parallax imagery, and the vertical views between
cameras are interpolated by depth image-based rendering technique. An improved
technique for depth estimation reduces the estimation error and high-density
light-field is obtained. The captured data is employed for the calculation of
computer hologram using ray-sampling plane. This technique enables high-resolution
display even in deep 3D scene although a hologram is calculated from ray
information, and thus it makes use of the important advantage of holographic 3D
display.
