Preliminary Experiments of a 3D Camera for High-Density Directional Image Generation

Abstract

We have proposed a natural 3D display which is based on high-density generation of directional images.In order to display photorealistic 3D images of real 3D objects, the most promising 3D camera technique is the generation of high-density directional images from multiple images captured using multiple horizontally aligned cameras by an interpolation algorithm.In this study we examined four simple interpolation algorithms. An algorithm that utilizes one representative object distance as a priori was found to be the most effective one. This technique enables a fast interpolation. There is, however, a tradeoff between the number of cameras and the allow-able depth of 3D objects. This tradeoff was examined theoretically and experimentally.
