Abstract
In order to achieve an immersive, natural 3D experience on a large screen, a
100-Mpixel multi-projection 3D display was developed. Ninety-six projectors were used to
increase the number of rays emanating from each pixel in the horizontal direction to 96.
Conventional algorithms use a large number of cameras or input images to process a large
number of light rays. This creates difficulties in the design of both the large
acquiring system and substantial memory storage. In this paper, we propose an efficient
light-field rendering algorithm that utilizes only a few input colors and depth images.
Using a depth map and estimated camera parameters, synthesized light-field images are
directly generated. This algorithm requires a much lighter memory load than conventional
light-field rendering algorithms. It is also much simpler than the image-based rendering
algorithm because it does not require the generation of so many multiview
images.
