摘　　要：针对2009年全国研究生数学建模竞赛B题，以自动比对方法的智能性，自动性和可操作性为出发点，以构建子弹头特征峰数据库，搭建子弹头自动比对系统为目标，对枪弹头痕迹的自动比对问题展开了研究．类比搜索引擎的关键词搜索技术建立了基于图形的特征峰搜索技术，实现了弹头痕迹的智能比对．This work study and solve the automatic matching problem for the bullet traces, which is the problem B of the National Graduate Mathematical Contest in Modeling. Based on the intelligent, automated and operable characters of the automatic matching method, we have constructed the database of the characteristic peaks of the bullets and developed the automatic matching systems. The searching technology of the characteristic peaks is analogous to that of the search engines of the keyword, which can be applied in the intelligent contrast of the bullet traces.
