A system and methods for automatically determining the states of game obj ect possession, including those of free, under contention and in possession, for sporting contests. The system uses the minimum necessary and sufficient data 100, including the predefined tracking layout 110, the current officia l game time-in versus time-out data 122, the current centroid location of ea ch player matched with their identity data 124 and the current centroid loca tion of the game object data 126 which is then converted deterministically i nto at least clock states 150, game object movement states 160, and optional ly into game object location states 170 and game object heading direction st ates 180. The system and methods also disclose the further combining of thes e states 150, 160, 170 and 180 into the determination of the cycle of posses sion flow 200, including the events of gaining control 210, exchanging contr ol 220 and relinquishing control 230. |
