    • The invention is directed to recording, transmitting, and displaying a three-dimensional image of a face of a user in a video stream. Reflected light from a curved or geometrically shaped screen is employed to provide multiple perspective views of the user's face that are transformed into the image, which is communicated to remotely located other users. A head mounted projection display system is employed to capture the reflective light. The system includes a frame, that when worn by a user, wraps around and grips the user's head. Also, at least two separate image capture modules are included on the frame and generally positioned relatively adjacent to the left and right eyes of a user when the system is worn. Each module includes one or more sensor components, such as cameras, that are arranged to detect at least reflected non-visible light from a screen positioned in front of the user.
    • 本发明涉及在视频流中记录,传输和显示用户的脸部的三维图像。 采用来自弯曲或几何形状屏幕的反射光来提供被转换成图像的用户脸部的多个透视图,其被传送到位于远处的其他用户。 采用头戴式投影显示系统来捕捉反射光。 该系统包括一个框架,当被使用者穿戴时,该框架环绕并抓住使用者的头部。 而且,至少两个单独的图像捕获模块被包括在框架上,并且当系统被佩戴时通常相对于用户的左眼和右眼定位。 每个模块包括一个或多个传感器组件,例如照相机,其被布置为至少检测来自位于用户前方的屏幕的反射的不可见光。

    • Systems and methods are described for defining a set of images based on captured images, receiving a viewing direction associated with a user of a virtual reality (VR) head mounted display, receiving an indication of a change in the viewing direction. The methods further include configuring, a re-projection of a portion of the set of images, the re-projection based at least in part on the changed viewing direction and a field of view associated with the captured images, and converting the portion from a spherical perspective projection into a planar perspective projection, rendering by the computing device and for display in the VR head mounted display, an updated view based on the re-projection, the updated view configured to correct distortion and provide stereo parallax in the portion, and providing, to the head mounted display, the updated view including a stereo panoramic scene corresponding to the changed viewing direction.
    • 描述了基于捕获的图像来定义一组图像的系统和方法,接收与虚拟现实(VR)头戴式显示器的用户相关联的观看方向,接收观看方向的改变的指示。 所述方法还包括至少部分地基于所改变的观察方向和与所捕获图像相关联的视场来配置,所述图像集合的一部分的重新投影,所述重新投影将所述部分从 球面透视投影成平面透视投影,由计算设备呈现并用于显示在VR头戴式显示器中,基于重新投影的更新视图,配置为校正失真并在该部分中提供立体视差的更新视图,以及 向头戴式显示器提供包括与改变的观看方向对应的立体全景场景的更新视图。
