A military cartridge includes four elements; case, capsule, ammunition and powder. While manufacturing, defects may occur in the case. These defects should be detected and the defected cases should be separated. Defects could occur in the mouth, surface and primer parts of the case. This paper proposes the methodology that involves the real-time inspection of the defects in the mouth part of the cases using image processing techniques. The algorithms of the proposed methodology were implemented on real images and the obtained results have showed that common defects such as split and dent defects occurring on the mouth part of the case can be detected with high accuracy.
