A Free-Viewpoint Video System for Visualisation of Sport Scenes (IBC) This contribution introduces a new approach of using multi-camera images of an event to provide a free-viewpoint video visualisation of sport scenes. This allows a virtual camera to be moved freely around and to view the action from any angle. The system is based on 3D reconstruction techniques previously developed for studio use. A number of different 3D representations, including billboards, visual hulls and view-dependent geometry are evaluated for the purpose.

First results show the potential of the new approach for action replay and strategy analysis of sport scenes. Current limitations of the 3D representations are discussed in the context of a practical use of the system.

Presented in Amsterdam, September 2006 at the International Broadcasting Conference, part of the International Broadcasting Convention (IBC).
