Computer vision system for tracking players in sports games

Abstract

The development of computer vision system for tracking players in indoor team games is presented. Several image processing and tracking methods are described, along with camera calibration and lens distortion correction. The output of the system consists of spatiotemporal trajectories of the players, which can be further processed and analyzed by sport experts. In some critical situations the automatic tracking process must be manually interrupted. To correct miss-trackings, human supervision is required. Some experimental results are presented as well.
