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.
