Abstract:

Bullet mark comparison is one of the key techniques in the discovery of evidences. A bullet mark comparison method was presented in this paper. First the bullet marks data are gathered according to generally used equipment. There are many coarse data cannot be used in matching process, so a preprocessing on the raw data is need. A statistics modeling is set up to construct a cost function, which can be used to evaluation choose of error until the cost function get minimum value. Experiment showed this comparison method can solve comparison problems of bullet mark.
