摘　　要：为了有效地提取枪弹头痕迹特征,提出了一种将三维弹痕数据转换成同形0-1特征点矩阵的方法。介绍了枪弹头痕迹产生的机理,分析了高精度数据采集设备获取枪弹头痕迹数据的过程,基于Hough空间变换模型,建立了从0-1特征点矩阵提取弹痕特征直线的模型,并对6支枪发射的12发弹的三维弹痕数据进行特征直线提取试验。实验结果证明,该方法能正确有效地提取弹痕特征直线。In order to taking gun bullet mark feature availably, the way of conversion from 3-D bullet mark data to same form 0-1 feature point matrix is proposed. The mechanism of gun bullet mark is introduced, the process of bullet mark data getting by high-precision data-taking equipment is analyzed, Based of Hough space conversion model, the model of bullet mark feature line taking from same form 0-1 feature point matrix is made. The experiment of gun bullet mark feature line taking from 12 3-D bullet mark data of 6 guns is carried out. The test result shows that the method can effectively extract the feature line in right way.
