| 摘 要： | 提出了一种新的子弹识别方法。首先将采集到的子弹图像进行Harris角点检测,提取特征点,然后将特征点位置坐标标准化,使用典型相关分析的方法计算得出两幅图像之间的相似度,以此相似度判定两枚子弹是否是同一枪支发射。实验结果表明,提取的特征点比较典型,置信度较高,对变形不严重的子弹检测有一定的实用价值。

| Abstract: | A new method for analyzing and comparing the bullet is prosposed.Firstly,use the method of Harris corner detector to detect and extract the feature point in bullet images;Secondly,standardize the coordinate of feature point and then use the method of canonical correlation analysis to compute the similarity of the two images;Lastly,identify whether the two bullets was fired from the same firearm.The experiments show that the feature point is typical and the result is reliable.The technique is useful especially for no distortional bullets. |
