3D-reconstruction of soccer scenes

The aim of this paper is to demonstrate the 3d reconstruction of human body poses and motions in the field of sports events. The reconstruction does not require any technical hardware but uses originally broadcasted television images only. A game scene is reconstructed as a 3-dimensional model and the user can look at this model not only in slow motion, but also from arbitrary positions and viewing angles of his/her choice. He/she can navigate through the scene assuming various viewing angles and positions. To judge on a penalty decision, the user can e.g. assume the viewpoint of the referee; or after a goal, the position of the goalkeeper can be taken to see whether the view on the ball was obstructed.
