摘要
目的评定人牙咬痕同一认定数字化分析方法的精确性。方法 采用数字化分析法对人牙咬痕及8名“疑犯”牙列模型进行双盲法分析实验,用Photoshop 5.5将获得的咬痕扫描图像生成overlay,用AutoCAD Rl4工程测量软件分析各项参数,比较人牙咬痕和“疑犯”牙列参数的匹配性。结果人牙咬痕及“疑犯”牙列模型数据化分析的各项参数分析结果一致。结论对于试验性咬痕,数字化分析是一种可行的认定方法,对法医学实践具有可行性及良好的应用前景。
Objective Digital analysis of human bitemarks by blind method was assessed for its accura-cy. Method Digital analysis was used in double-blind method for identification of human bitemarks with control samples from 8 suspects. Photoshop 5.5 generates an overlay from bitemarks scanned and various coefficients were submitted for analysis by AutoCAD R14 engineering software to compare bitemarks with denture of suspects. Results Digital analysis shows that bitemarks tally with cast of denture from 'suspects' in every coefficient. Conclusion Digital analysis is feasible for identification of experimental bitemarks and promises sound prospects in future forensic practice.
