摘要

我们描述了一个交互式、实时、多摄像头视频采集和显示系统。该系统几乎完全基于软件,因此具有灵活性和可扩展性。计算和数据存储由卡内基梅隆-英特尔公司的iWarp计算机提供。视频显示是通过高性能并行接口网络写入高分辨率帧缓冲区来完成的,视频可以在捕获时显示,只有一帧延迟。我们提供了一个在主机工作站上运行的类似录像机的图形界面的交互性,该界面反过来控制捕获系统的操作。该系统允许用户交互式地监控、捕获和重放视频,使用VCR很方便,但具有灵活性和性能,除了最昂贵和定制的视频捕获系统之外,其他所有系统都无法实现。

Design, implementation, and performance of a scalable multi-camera interactive video capture system
We describe a system for interactive, real time, multi-camera video capture and display. The system is almost entirely software-based and as a result is flexible and expandable. Computation and data storage is provided by the Carnegie Mellon-Intel Corporation iWarp computer. Video display is accomplished using a High Performance Parallel Interface network to write to a high resolution frame buffer Video can be displayed as it is captured, with only a single frame latency. We provide interactivity with a VCR-like graphical interface running on a host workstation, which in turn controls the operation of the capture system. This system allows a user to interactively monitor, capture, and replay video with the ease of use of a VCR, yet with flexibility and performance that is unavailable in all but the most expensive and customized video capture systems.
