我们提出了一种用于合成多对多视频电话会议的视图的系统和技术。我们不是为每对用户复制Oneto-One系统,也不是执行复杂的3D场景采集,而是依赖于用户对软中断的容忍度来实现我们的渲染技术。此外,我们观察到,在视频会议期间,参与者的眼睛通常保持在恒定的高度(坐高),因此我们只需要能够在水平面上合成新的视图。我们演示了一个使用线性摄像机阵列来执行光场样式渲染的实时系统。光场渲染的简单性和健壮性,加上视频电话会议中有限视场体积的自然限制,使我们能够以交互速率为一组参与者合成照片级逼真的视图。
We present a system and techniques for synthesizing views for many-to-many video teleconferencing. Instead of replicating oneto-one systems for each pair of users, or performing complex 3D scene acquisition, we rely upon user tolerance for soft discontinuities for our rendering techniques. Furthermore, we observed that the participants’ eyes usually remain at a constant height (sitting height) during video teleconferencing, thus we only need to be able to synthesize new views on a horizontal plane. We demonstrate a real-time system that uses a linear array of cameras to perform Light Field style rendering. The simplicity and robustness of Light Fielding rendering, combined with the natural restrictions of limited view volume in video teleconferencing, allow us to synthesize photo-realistic views for a group of participants at interactive rate.
