本文描述了一种称为交互式 3D 数字视频的新视觉媒体。 3D 数字视频在播放期间从观看者控制的虚拟摄像机的角度显示现实世界事件的动态图片。为了使 3D 视频变得实用，需要复杂的数据操作、管理和处理能力。考虑到所涉及数据的数量和复杂性，这些任务是艰巨的。此外，由于 3D 视频数据的混合性质，没有可用的标准化表示和编码方案。我们探讨这些问题并概述称为沉浸式视频的功能系统。对于篮球比赛等真实事件，沉浸式视频分析和合成录制的多视点视频以创建事件的完整 3D 版本，然后对其进行编码和存储以进行沉浸式播放。在重播这部 3D 数字电影时，观众可以从任何角度连续探索场景。我们描述了我们为使用互联网基础设施和客户端服务器配置所采取的步骤，以允许万维网用户交互式地观看我们的任何实验性 3D 视频，包括由六个摄像机捕获的一分钟分阶段空手道演示。这种新媒体的应用包括远程呈现、交互式视频和电视、基于视频的虚拟环境以及沉浸式故事片。
This paper describes a new visual medium called interactive 3D digital video. 3D digital video displays motion pictures of real-world events from the view of a virtual camera controlled by the viewer during playback. For 3D video to become of practical use, sophisticated data manipulation, management and processing capabilities are required. These tasks are daunting, given the amount and complexity of data involved. Furthermore, due to the hybrid nature of the 3D video data, no standardized representation and coding schemes are available. We explore these issues and present an overview of a functional system called immersive video. For real events such as basketball games, immersive video analyzes and composites recorded multiviewpoint videos to create a full 3D version of the event which is then encoded and stored for immersive playback. While replaying this 3D digital movie, viewers are able to explore the scene continuously from any perspective. We describe the steps we have taken toward using the Internet infrastructure and a client-server configuration to allow World Wide Web users to interactively view any of our experimental 3D videos including a one minute staged karate demonstration captured by six video cameras. Applications of this new medium include telepresence, interactive video and television, video-based virtual environments, and immersive feature films.
