A Shooting Training and Instructing System Based on Image Analysis

The main shortcoming of the traditional way to train shooting athletes is that the effect is hard to be evaluated without live firing. We have designed and implemented a computer-aided shooting training and instructing system that can help coaches and athletes do more quality than quantity work. The minimum system consists of 6 components: a gun, a laser aiming device, a target, a camera, an image card and a computer. It works as follows: the camera snaps a target image, then the aiming point which is marked by the laser spot is extracted from the image and the corresponding score is calculated and printed in the screen in real time. The trace of the aiming point in a training session is also drawn in the screen. The system can prompt the best trigger moment. Based on the recorded performance data in the whole training session, the coach can make objective evaluation on the training effect and give pointed instructions to the athlete. The evaluation and instructions can be made by the expert system instead. Up to 16 targets can be processed simultaneously by one system.
