Abstract
First, We attempted to automate the process of analysis of American Football play that needs much time heretofore. We recognized the play from the video of American Football. Play recognition requires time-series positional data of players and lines. Trajectory of players is formed from them. We recognized the runnning pattern by comparing the trajectory to registerd data. And we recognized the defult position by using data of formation. Second, We attmpted to construct the system of play simulation. We simulated the play of defensive players. The defensive players in the simulator have AI that is the process of the thinking of the real defensive player of American Football. The offensive players in the simulator are made to run the set coruse. We replayed the result of simulation in the game map.
