Abstract

In this paper, we describe a rendering system that is capable of capturing and rendering dynamic environments at about 20 fps using a commercially available PC (1.8 GHz single processor) and IEEE 1394 cameras (each with resolution of 320times240). It does not rely on any additional custom hardware. Such a system permits streaming applications that involve real-time view synthesis from multiple cameras, such as 3D teleconferencing or chatting. View synthesis is performed using the closest two cameras, and relies on plane sweeping to produce a photoconsistent virtual image. In addition, an alpha matte is estimated at the virtual view in order to improve the rendering quality at the foreground/background boundaries. We illustrate the performance of our system on several dynamic environment examples.
一个实时虚拟环境渲染系统
在本文中,我们描述了一个渲染系统,该系统能够使用商用PC (1.8 GHz单处理器)和IEEE 1394相机(每个分辨率为320倍240)以大约20 fps的速度捕获和渲染动态环境。它不依赖于任何额外的定制硬件。这样的系统允许流媒体应用,包括来自多个摄像头的实时视图合成,如3D远程会议或聊天。视图合成是使用最近的两个相机进行的,并依赖于平面扫描来产生光一致的虚拟图像。此外,为了提高前景/背景边界的渲染质量,在虚拟视图中估计alpha哑光。我们在几个动态环境示例中演示了系统的性能。
