N2 - We present an AR display system for observing sports events on a desktop stadium based on fcamera tracking using pattern of the desktop ground by overlaying players in real sports events captured with multiple cameras. In this paper, we take soccer as the sports event. In the proposed system, the pose and the position of an observing camera are estimated in real-time by using a soccer field pattern on the desk top and an AR marker. The soccer field pattern in the desktop stadium on which the object soccer game is observed via AR display is previously registered with the real soccer stadium in which the real soccer game is captured with multiple cameras. In the previous procedure, we also estimate camera parameters (projection matrices) of the multiple cameras capturing the real soccer game using planar structures in the soccer field. Positions of soccer player and ball are also previously estimated based on the camera parameters. In the on-line procedure for AR display, the textures of the players captured in the multiple soccer video are simply overlaid onto AR camera videos with CG models which are generated for giving additional visual information.
