Abstract: Methods, systems and apparatuses may provide for technology that selects a player from a plurality of players based on an automated analysis of two-dimensional (2D) video data associated with a plurality of cameras, wherein the selected player is nearest to a projectile depicted in the 2D video data. The technology may also track a location of the selected player over a subsequent plurality of frames in the 2D video data and estimate a location of the projectile based on the location of the selected player over the subsequent plurality of frames.

Abstract: A method for player and ball tracking post processing is described herein. The method includes optically tracking a trajectory of a player and ball and determining at least one affinity player for the currently tracked player. Additionally, the method includes completing the optical trajectory for the currently tracked player based on an estimated trajectory from the affinity player and stabilizing ball tracking during game break. The method further includes calculating virtual camera movement.

Abstract: An example system for game status detection and trajectory fusion is described herein. The system includes a tracker to obtain a ball position and a player position based on images from a plurality of cameras and a fusion controller to combine multiple trajectories that are detected via the ball position to obtain a fused trajectory. The system also includes a finite state machine configured to model a game pattern, wherein a game status is determined via the ball position, the player position and the fused trajectory as input to the finite state machine.
