Hexagonal image representation for 3-D photorealistic reconstruction

A new data structure for representing the color of rays from multiple-view images is presented. The structure is a hexagonal tessellation generated from a buckyball. Using the structure, the captured colors are represented as pixel values of a hexagonal image, and the image is finally saved as a compressed normal image after a simple transformation without loss of connectivity. A surface light field data generating algorithm based on image-based scheme is also presented It assigns color for each vertex of the reconstructed surface using the structure. The experimental results show that the algorithm yields the surface light field data in a short time. In addition, photorealistic rendered views are obtained from arbitrary viewpoints.
