在本文中，我们描述了一种新的远程呈现系统，它使用户能够在网络环境中轻松地查看虚拟现实世界。该系统包括浏览器上的全方位视频浏览器，并允许用户在浏览器上浏览全方位的视频内容。全向视频查看器以Active-X程序实现，用户只需打开包含全向视频内容的网站即可自动安装查看器。该系统允许不同地点的许多用户在不同地点查看场景，就像使用多播协议的交互式电视一样，而不增加网络流量。本文描述了该系统的实现，并使用实时和存储的视频流进行了实验。在存储视频流的实验中，系统采用了全方位多摄像头系统进行视频采集。我们可以浏览高分辨率和高质量的视频内容。在视频直播实验中，车载全向摄像头采集汽车周围的全方位视频流，在户外环境中运行。采集的视频流使用多播协议通过无线和有线网络传输到远程站点。我们可以在任意方向上自由地看到直播视频内容。在这两个实验中，我们使用头盔显示器(HMD)和陀螺传感器实现了依赖于视觉的呈现，以实现更丰富的呈现。
In this paper, we describe a new telepresence system which enables a user to look around a virtualized real world easily in network environments. The proposed system includes omni-directional video viewers on web browsers and allows the user to look around the omni-directional video contents on the web browsers. The omni-directional video viewer is implemented as an Active-X program so that the user can install the viewer automatically only by opening the web site which contains the omni-directional video contents. The system allows many users at different sites to look around the scene just like an interactive TV using a multi-cast protocol without increasing the network traffic. This paper describes the implemented system and the experiments using live and stored video streams. In the experiment with stored video streams, the system uses an omni-directional multi-camera system for video capturing. We can look around high resolution and high quality video contents. In the experiment with live video streams, a car-mounted omni-directional camera acquires omni-directional video streams surrounding the car, running in an outdoor environment. The acquired video streams are transferred to the remote site through the wireless and wired network using multi-cast protocol. We can see the live video contents freely in arbitrary direction. In the both experiments, we have implemented a view-dependent presentation with a head-mounted display (HMD) and a gyro sensor for realizing more rich presence.
