Networked immersive telepresence with high-resolution omnidirectional video streams

摘要

Recently, the demand of a telepresence system that provides a user with the scene of a remote site as an image with rich sensation is increasing. We have proposed the telepresence systems with an omnidirectional camera that enables us to instantly look around a remote site. However, the systems had some problems such that they did not use the network and the resolution of displayed image was poor because the standard NTSC camera was used for the portion of omnidirectional cameras. This paper describes a real-time networked telepresence system, which transports high-resolution omnidirectional video streams acquired by the omnidirectional HD camera to the remote site through the network, and presents a user's view-dependent video stream to immersive displays such as an HMD and a spherical projection display.
