【摘要】：研究人牙咬痕同一认定的数字化分析方法及其精确性。通过动物实验造成人牙咬痕,并对咬痕和疑犯牙列的相关参数进行数字化记录处理,包括获取咬痕数字化图像:扫描疑犯牙列、疑犯蜡牙合、疑犯咬痕,用AdobePhotoshop5.5生成Overlay,测量Overlay参数,比较咬痕和疑犯牙列参数(包括研究模、蜡牙合及咬痕)的匹配性。结果证明,咬痕同一认定数字化分析具有较高的精确性,可对人牙咬痕作出精确的认定。在咬痕同一认定和疑犯牙列证据的收集中,疑犯研究模、疑犯蜡牙合、疑犯咬痕均具有实际意义,其中以疑犯研究模型的精确性最高。
[Abstract]:To study the digital analysis method and its accuracy of the same identification of bite marks in human teeth.Through animal experiments, human teeth bite marks are created, and the relevant parameters of bite marks and suspect dentition are digitally recorded, including obtaining digital images of bite marks: scanning the suspect's dentition, the suspect's wax occlusion, the suspect's bite mark, the image of the suspect's dentition, the suspect's wax occlusion, and the suspect's bite mark.Overlay was generated by AdobePhotoshop5.5, and Overlay parameters were measured to compare the matching between bite marks and suspect dentition parameters (including model, wax occlusion and bite mark).The results show that the digital analysis of the same identification of bite marks has high accuracy and can be used to identify the bite marks of human teeth.In the identification of the same bite mark and the collection of evidence of the suspect's dentition, the suspect's research model, the suspect's wax occlusion and the suspect's bite mark are of practical significance, among which the suspect research model has the highest accuracy.
