Abstract: Augmented reality systems provide graphics over views from a mobile device for both in-venue and remote viewing of a sporting or other event. A server system can provide a transformation between the coordinate system of a mobile device (smart phone, tablet computer, head mounted display) and a real world coordinate system. Requested graphics for the event are displayed over a view of an event.

Abstract: Video frames of a baseball game are analyzed to determine a track for the participants in the game, e.g., players, coaches and umpires, and to update a digital record of the game. The start and/or end of a half-inning can be indicated by factors such as: the participants leaving the dugout region and entering the playing field, including the outfield, a participant leaving the dugout region and entering the region of a base coach's box, a pitcher throwing pitches when no batter is present, and players on the playing field throwing the ball back and forth to one another. In one approach, the combination of detecting an event which is known to occur most often or always between half-innings followed by detecting another event which is known to occur most often or always during a half-inning, can be used to signal that a half-inning has started.

Abstract: Video frames of a baseball game are analyzed to determine a track for the participants in the game and to update a digital record of the game. The merging of participants in a video frame is resolved by associating the participants' tracks before and/or after the merging with a most likely participant role, such as a player, coach or umpire role. The role of one merged participant can be used to deduce the role of the other merged participant. In this way, the digital record can be completed even for the merged period. The role of a participant can be based, e.g., on the location of the participant relative to a base, a coach's box region, a pitcher's mound, a dugout, or a fielding position, or by determining that a participant is running along a path to a base or performing some other movement.
