Ray capture systems for FTV

FTV (Free-viewpoint Television) is an innovative visual media that allows users to view a 3D scene by freely changing their viewpoints. Thus, it enables realistic viewing and free navigation of 3D scenes. FTV is the ultimate 3DTV with infinite number of views and ranked as the top of visual media. FTV is not a conventional pixel-based system but a ray-based system. Ray capture, processing and display technologies have been developed for FTV. Here, three types of ray capture systems are presented. They are multi-camera ray capture with view interpolation, all-around dense ray capture without view interpolation and computational ray capture by reduced number of pixel data.
