在现代法庭科学领域中,足迹检验鉴定技术是应用广泛、历史悠久、作用突出的专业技术之一,在我国刑事科学技术占有一定的重要性。通过对现场遗留足迹的分析,缩小侦查范围,进而为确定犯罪嫌疑人提供帮助。这是足迹检验技术在侦查中的重要作用。以往的实验并未对局部足型的特征做出系统的统计和划分,本文抽取身高在160cm-188cm的各类人群205枚足迹作为研究对象,通过概率与数理统计的方法对足型局部特征进行系统的总结与分析,进而为日后公安技术工作提供一个可参考的数据。
In the field of modern forensic science, footprinting and identification technology is one of the most widely used, long-established and prominent professional techniques, which holds a certain importance in criminal science and technology in China. By analyzing the left footprints of the scene, the scope of the investigation can be narrowed, which can help to determine the suspects. This is the important role of footprinting in the investigation. Previous experiments did not make systematic statistics and classification of the characteristics of the local foot type. In this paper, 205 footprints of all kinds of people with a height of 160cm-188cm were taken as the research object. The foot-type local features were analyzed by means of probability and mathematical statistics System summary and analysis, and then provide a reference data for the public security technology work in the future.
