Target shooting is a military, sportive and for safety activity. As this activity rises, the automation of indoor shooting ranges becomes a need. Therefore, this paper proposes a program that, automatically, detects bullet holes in fixed targets and calculates score values. This purpose is achieved by a C++ code based on mathematical morphology and analysis of bullet holes locations in targets. The program is indicated to indoor shooting ranges and it works with images captured by a digital camera. Images of two types of targets were used for data collection. These targets were subjected to sessions of shots and then their images were processed. The achieved results are presented and they show the importance of this program to detect bullet holes and to calculate score values. The success rates for the bullet holes detections and scoring are approximately 97% and 100%, respectively. Thus, this work contributes to benefit the automation of indoor shooting ranges.
