线形工具痕迹比对的计算机辅助程序设计

Computer Aided Programming for Comparative Examination of Line Traces

大量实验表明,工具造痕部位上的凸点以较为稳定的作用方式在承痕体上刮擦时,会在承痕体上形成相对平行的线形痕迹,这些凸点的间距与这些线痕的间距存在对应比例关系。依据这一规律,设计了一种计算机算法,通过模糊排查嫌疑工具造痕部位的凸点与线形痕迹的对应情况,推断可疑造痕工具形成现场痕迹的可能性及可能的形成方式,为工具痕迹检验提供辅助性判断依据。

A mass of experiments indicate that when the protuberant points of tool scrape a object, those points can shape many line traces which parallel between each other on the object, and there is a sort of corresponding proportion between the distances among those points and the distances among those line traces in substance. According to this rule, a sort of computer arithmetic is designed to deduce the probability that the suspectable tool shapes alibi traces and how to shape them by fuzzily investigating the corresponding complexion between the protuberant points of the suspectable tool and the line traces, which can supply a sort of aided judgment foundation for tool trace checkout.
