SYSTEMS AND METHODS FOR TRANSLATING SPORTS TRACKING DATA INTO STATISTICS AND PERFORMANCE MEASUREMENTS

摘要

System and methods for automatically determining states of game object possession for sporting contests. The system uses the minimum necessary and sufficient data, including the predefined tracking layout, official game time-in versus time-out data, centroid location of each player matched with their identity data and centroid location of the game object data which is then converted deterministically into at least clock states and game object movement states. The system and methods also disclose the further combining of these states into the determination of the cycle of possession flow. For determining the states of possession of the game object, the system and methods disclose using either an instantaneous or average measured distance between each player and the game object in combination with a minimum radius defining each player's area of influence and a minimum time necessary for the game object to be within this area before possession can be assigned.

1. A system for automatically determining the states of game object possession, including those of free, under contention and in possession, for sporting contests conducted within a predefined area of pre-known layout, comprising:
a system for tracking the on going changes to the official game time so as to detect time-in play versus time-out of play; a system for tracking the on going locations of each player, matched to their identity, at least within the predefined area in accordance with the pre-known layout, a system for tracking the on going locations of the game object, at least within the predefined area in accordance with the pre-known layout, a computer for receiving the time-in and time-out data, the player location by identity data as well as the game object location data, in coordination for given instants of measurement, and an algorithm operative on the computer for determining the game object states including free, under contention and in possession, for each instant of received data by measuring the distance between each player and the game object, for comparing this distance to some minimum radius per player beyond which the game object cannot be in their possession, for setting the state of the game object to a classification of free if it lies outside of the minimum radius of all players, for setting the state of the game object to a classification of under contention if in the previous state it was free or not assigned to any one player's possession and it now lies within the minimum radius of one or more players, for setting the state of the game object to a classification of in the possession of any player for which the game object has remained within that player's minimum radius for some minimum time during which some other player may have been under contention but no longer is within reach of the game object.
