2) firing pin mark
击针头痕迹
3) arc striking mark
电焊打火痕迹
4) firing-pin impression
冲击磨损痕迹
1.
By collecting the images of the cartridge cases shot by four kinds of guns,it was found that the circumference of the firing-pin impression appeared as an irregular jigsaw shape,showing its nonlinear nature and fractal characteristics.
对4种枪支发射的弹壳进行图像采集,经观察发现冲击磨损痕迹周边均为锯齿状不规则形态,表明其是非线性的且具有分形特征;应用分形理论的周长-面积公式和最小二乘法原理,对所采集的4种枪支的冲击磨损痕迹图像进行分析计算的结果表明,枪种不同,所配用击针头的形状、尺寸不同,冲击磨损痕迹图像的分形维数值也不同,因此可以用分形维数来描述弹壳上不同枪支的冲击磨损痕迹特征,从而为冲击磨损痕迹的量化检验作出初步的探索。
