局部特征在弹体裂纹图像分割中的应用

摘要

The detailed characteristics of original or terminal end of projectile crack are the key criteria to determinate crack. Aiming at the algorithmic drawback of traditional image segmentation, the image segmentation algorithm of crack was put forward based on local characteristics on the sh-ell crack of different-type HE (high explosive) projectile. Simulation results indicated that the new method is of good anti-highlight, clear original orterminal end of crack, etc. in comparison with traditional one,which obtains the expected image effect.%弹体裂纹的起始/终止端细节特征是判定裂纹类型的重要依据.以不同型号杀爆弹弹体裂纹为研究对象,针对传统图像分割算法的不足,提出一种基于局部特征的裂纹图像分割算法.在Matlab编程环境下进行的验证结果表明:与传统方法相比,新方法具有抗高光性好、裂纹的起始/终止端细节清晰等优点,得到了期望的图像效果.
