A low-cost video-based system has been developed for tracking the muzzle of the rifle before the shot using image processing algorithms. A video camera set up in a distance of about 5 m in front of the athlete in a laterally displaced position records the barrel. The camera is connected to a computer, and a LabVIEW application is used to track the shape of the muzzle automatically. The results show that a resolution of video cameras usual in trade (720 × 576 pixel) is sufficient for acquiring the rather small motion of the muzzle.
