由于每个人的足部趾区生理结构的不同,导致该区域形态分布特征具有较高的特定性。基于这种特性,提出构建一种新的数学坐标模型,将赤足趾区各脚趾中心与设定的坐标原点距离、角度等特征量进行统计、分析,归纳总结出赤足足迹趾区各特征量的检验价值高低,为在一定可靠的概率下利用赤足足迹进行人身认定提供有力理论支持。
Due to the different physiological structures of the foot and toe area of each person, the morphological distribution characteristics of the area are highly specific. Based on this characteristic, a new mathematical coordinate model is proposed, and the feature quantities such as the distance and angle between the toe centers of the toe region and the origin of the coordinates are calculated, and the features of the toe region of the barefooted footprints are summarized Test the value of high and low, in order to provide reliable theoretical support for the use of barefoot footprint for personal identification with a certain probability of reliability.
