    • A system and method for stereoscopic video teleconferencing provides an immersive virtual meeting experience. Each participant is surrounded by at least two video cameras. The system senses the position of each of the participants and uses this information to select, for each participant, camera pairs to capture a stereo pair of video images of each of the other participants. The system is adapted to isolate the image of each participant from the background. The system transforms the stereo pair images to adjust the perspective for the interocular spacing of each participant. The processed stereo pairs of video images are transmitted to the respective participants. For each participant, the system assembles a stereo video display image of a virtual meeting room, combining the stereo pair images of each of the other participants appropriately sized and positioned. Three-dimensional (3D) virtual objects can also be displayed and manipulated by participants.
    • 用于立体视频电话会议的系统和方法提供了沉浸式的虚拟会议体验。 每个参与者被至少两个摄像机包围。 该系统感测每个参与者的位置,并使用该信息为每个参与者选择相机对以捕获每个其他参与者的立体声视频图像对。 该系统适于将每个参与者的图像与背景隔离开来。 系统转换立体声对图像以调整每个参与者的眼间距的透视图。 经处理的视频图像的立体对被发送给相应的参与者。 对于每个参与者,系统组装虚拟会议室的立体声视频显示图像,组合其他每个参与者的立体声对图像适当地大小和定位。 三维(3D)虚拟对象也可以由参与者显示和操纵。
