摘要: 弹头发射痕迹的比对是破获涉枪案件的关键之一,我国目前在这方面采用的方法都是依靠枪弹痕迹专家在比对显微镜下对所有待比的弹头逐一进行两两比对。这种低效的方法已无法适应形势发展的需要。本文介绍了一种新型弹头发射痕迹计算机图像比对系统,包括系统的硬件结构,软件功能以及主要技术关键及其解决方法。该系统较好地解决了原先的弹头发射痕迹比对方法中存在的问题,实践结果表明具有较高的应用推广价值。

Abstract: Bullet mark comparison is one of the key techniques in the discovery of evidences in gun relat?ed cases. So far, the methoa in use domestically still resides in the personal experience of experts in their comparison among the candidate bullets under the comparison microscope. This process is tedious and low in efficiency and cannot suit the requirements of development. A new bullet mark computer image compar?ing system is proposed including its hardware structure, software function and key technology. Practice shows that the system overcomes the original problems, and is worthy of being popularized.
