我们提出了一个基于实时视频渲染系统使用网络摄像机阵列。我们的系统包括64个商品网络摄像机，通过千兆以太网连接到一台PC。为了呈现高质量的新颖视图，我们通过使用分层表示来实时估计与视图相关的每像素深度图。渲染算法完全在GPU上实现，这使得我们的系统能够有效地独立和并行地使用CPU和GPU。使用QVGA输入视频分辨率，我们的系统渲染一个自由视点视频高达30 fps取决于渲染参数。实验结果表明，高质量的图像合成从各种场景。
We present a real-time video-based rendering system using a network camera array. Our system consists of 64 commodity network cameras that are connected to a single PC through a Gigabit Ethernet. To render a high-quality novel view, we estimate a view-dependent per-pixel depth map in real-time by using a layered representation. The rendering algorithm is fully implemented on a GPU, which allows our system to efficiently use CPU and GPU independently and in parallel. Using QVGA input video resolution, our system renders a free-viewpoint video at up to 30 fps depending on rendering parameters. Experimental results show high-quality images synthesized from various scenes.
