AR baseball presentation system based on registration with multiple markers

The AR Baseball Presentation System is an entertainment tool allowing users to watch "virtual baseball game" on the real tabletop field model through a web-camera attached to a LCD monitor. Our system uses multiple planar markers for geometrical registration of virtual catoons onto the tabletop field model. In contrast with most AR applications using multiple planar markers, we can place the markers at arbitrary positions and poses without measuring those arrangements manually. Since the markers can be placed at various positions and poses, the registration of the virtual objects becomes more stable than placing all the markers on the same directions. The baseball game scene is generated from the log history data of the baseball game.
