The Prometheus project has investigated new ways of creating, distributing and displaying 3D television. The tools developed will also help today’s virtual studio production. 3D content is created by extension of the principles of a virtual studio to include realistic 3D representation of actors. Several techniques for this have been developed: • Texture-mapping of live video onto rough 3D actor models. • Fully-animated 3D avatars: • Photo-realistic body model generated from several still images of a person from different viewpoints. • Addition of a detailed head model taken from two close-up images of the head. • Tracking of face and body movements of a live performer using several cameras, to derive animation data which can be applied to the face and body. • Simulation of virtual clothing which can be applied to the animated avatars. MPEG-4 is used to distribute the content in its original 3D form. The 3D scene may be rendered in a form suitable for display on a ‘glasses-free’ 3D display, based on the principle of Integral Imaging. By assembling these elements in an end-to-end chain, the project has shown how a future 3D TV system could be realised. Furthermore, the tools developed will also improve the production methods available for conventional virtual studios, by focusing on sensor-free and markerless motion capture technology, methods for the rapid creation of photo-realistic virtual humans, and real-time clothing simulation.
