Highly Realistic 3D Display System for Space Composition Telecommunication

In this paper, we describe a highly realistic 3D display system that generates composites of current and remote places for telecommunication purposes. It uses a 3D projector and head tracking to display a person in a remote place as a life-size stereoscopic image against background scenery. Since it generates displayed images that correspond to the observer's viewing position, it reproduces well the fidelity of existence and the feel of materials. We also describe a simple, fast, and high quality background scenery generation method, the development of which was inspired by the visual effects of depth-fused 3D (DFD) displays, and applied to a single direction conceptual demonstration system. Our system is a promising means for achieving real-time communication between two different places in cases where a sense of reality is required.
