Abstract

The advent of high-speed network and high performance PCs has prompted research on networked telepresence, which allows a user to see virtualized real scenes in remote places. View-dependent representation, which provides a user with arbitrary view images using an HMD or an immersive display, is especially effective in creating a rich telepresence. The goal of our work is to realize a networked novel view telepresence system which enables multiple users to control the viewpoint and view-direction independently by virtualizing real dynamic environments. In this paper, we describe a novel view generation method from multiple omni-directional images captured at different positions. We mainly describe our prototype system with high-scalability which enables multiple users to use the system simultaneously and some experiments with the system. The novel view telepresence system constructs a virtualized environment from real live videos. The live videos are transferred to multiple users by using multi-cast protocol without increasing network traffic. The system synthesizes a view image for each user with a varying viewpoint and view-direction measured by a magnetic sensor attached to an HMD and presents the generated view on the HMD. Our system can generate the user’s view image in real-time by giving correspondences among omni-directional images and estimating camera intrinsic and extrinsic parameters in advance.
