在刑事犯罪的现场上,工具痕迹是出现频率相当高的痕迹之一。但是随着指纹自动识别技术和其他自动识别技术的涌现及在实践中娴熟的应用,促使工具痕迹的提取和检验鉴定显得不足为重。工具痕迹检验随之渐渐地被办案人员忽视,导致工具痕迹出现率高但利用率低的现象普遍存在。本文着重介绍了数字化研究对工具痕迹的有利的分析和在实践中应用,以及在工具痕迹数字化研究中存在和注意的问题。 At the scene of criminal offenses, tool marks are one of the more frequently occurring signs. However, with the automatic identification of fingerprints and other automatic identification technology and the emergence of skilled applications in practice, to promote the extraction and testing of tool marks is not enough emphasis. Followed by tool inspection gradually ignored by investigators, resulting in high incidence of tool marks, but low utilization of the prevalence of the phenomenon. This article focuses on the beneficial use of digitization tools for tool trace analysis and its application in practice, as well as the issues that exist in digital tool trace research and pay attention to it.
