Abstract: Panoramic three-dimensional (3D) imaging systems for capturing stereoscopic video images and presenting 3D video images to a viewer based on the captured stereoscopic video images are disclosed. In some embodiments, the described systems use a proposed parallax vector to encode captured stereoscopic video images in real-time when the raw video images are being captured. During panoramic video playback, the computed parallax vectors are used to reproduce stereoscopic video images based on the angle of view of an audience relative to a display screen before outputting the stereoscopic video images to the left and right eyes of the audience to create the realistic 3D experience.
