Abstract: Aiming at the current problems that the way of fuse detection has low efficiency and requires manual intervention, a new algorithm of automatic detection for fuze based on ICT scanning image is presented.The security states of the fuze can be given by comparing the target region center of gravity for two cross-sectional images.The testing results show that the algorithm presented in this article not only improves the defect of traditional detection methods but also decreases the false alarms rate remarkably.
