耳廓的同一认定研究

The research of individual identify by comparison of auricle

目的研究耳廓观测指标的变化特征,提出利用耳廓特征识别点进行个体同一认定的研究方法,为法医学个体识别,及对视频图片中的个体进行同一认定,提供一种科学、准确、简便易行的方法。方法通过对19岁至22岁的汉族成人拍摄耳廓侧位图像,选取148人照片中的相应指标进行观测,数据收集,经SPSS统计软件处理,分析各种因素对测量结果的影响,计算出各指标识别能力及两批照片各指标之间的差值,最终得出各指标差值的参考值范围。结果 10项观测指标经统计检验分析,最终保留6项指标,重复测量结果稳定。各指标的变异系数相差不大,结果稳定可靠。结论通过制定6项观测指标差值的参考范围,确定指标是否同一,最终认定照片中耳廓是否属于同一个体的方法准确可行。

Objective To study the characteristics of measurement points in auricle and to make a method of individual identification by auricle. To make an accurate, simple and reliable individual identification recognition to forensic anthropology by the auricle in the videos and pictures. Methods To select measurement points by the auricle pictures of the 148 adults of Han nationality-from 19 to 22 years old-beyond one month and to analysis the data by SPSS statistical software, analyzing the various factors that influence on the measurement result, then to calculate the ability of recognition, and to confirm the each index difference and the reference value range between the two batch of photos in the end. Results The 6 measurement points were retained by statistical test from the 10 measurement points. The result is stable, and the variation coefficient of each index is not quite different. Conclusion To confirm reference range of the 6 observation points so that to determine whether the two auricle pictures belong to the same individual is accurate and feasible method.
