An automatic scoring system for air pistol shooting competition based on image recognition of target sheets

Traditionally, the shooting scores for air pistol competition are recognized and recorded manually. This paper proposed an automatic version. With image processing techniques, the location of a bullet hole and the serial ID number on a target sheet are identified, respectively, to calculate the score earned by the shooter with that ID number. The experimental results show that the proposed system can automatically identify scores with very high precision. Therefore, the proposed system is possible to replace the traditional scoring system.
