The topography of bullet surface wear was studied by using fractal theory. The irregularity and random distribution of its surface wear show the fractal characteristics.
Based on fuzzy set theory target recognition method, through CCD image collection, the difference between target and bullet track gradation were used to evaluate the firing grade.
基于模糊集理论目标识别方法，通过CCD图像采集，利用目标与弹迹灰度的不同，对射击成绩进行评价。

According to the experiments and theory analysis of the crackle on the glass by bullet hitting, we get the relationship between the glass crackle and the distance of shooting.
