使用三维面部扫描系统来获得面部模型是越来越感兴趣的，然而，便携式面部扫描设备的可靠性的系统评估还没有被广泛进行。因此，进行了系统的回顾和荟萃分析，考虑到与固定面部扫描系统获得的面部模型相比，便携式面部扫描仪获得的面部模型的准确性。根据系统性综述和荟萃分析的首选报告项目指南，在电子数据库中对2009年1月1日至2020年3月18日发表的文章进行了系统性文献检索。共识别出2806篇文章，其中21篇文章可用于叙述性综述，9项研究可用于荟萃分析。荟萃分析显示，便携式扫描仪生成的数字人脸模型的准确性与固定式人脸扫描系统的准确性没有显著差异（标准平均差（95%置信区间）=-0.325 mm（-1.186至0.536）; z =-0.74; p = 0.459）。在便携式系统的比较中，没有发现统计学上的显着差异，关于面部模型的准确性之间的扫描方法（p = 0.063）。总的来说，便携式面部扫描设备可以被认为是可靠的，用于获得面部模型。然而，在应用面部扫描仪时，在扫描设备设置、控制非自愿面部运动、地标和面部区域识别以及扫描协议方面需要谨慎。
The use of three-dimensional face-scanning systems to obtain facial models is of increasing interest, however, systematic assessments of the reliability of portable face-scan devices have not been widely conducted. Therefore, a systematic review and meta-analysis were performed considering the accuracy of facial models obtained by portable face-scanners in comparison with that of those obtained by stationary face-scanning systems. A systematic literature search was conducted in electronic databases following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for articles published from 1 January 2009 to 18 March 2020. A total of 2806 articles were identified, with 21 articles available for the narrative review and nine studies available for meta-analysis. The meta-analysis revealed that the accuracy of the digital face models generated by the portable scanners was not significantly different from that of the stationary face-scanning systems (standard mean difference (95% confidence interval) = −0.325 mm (−1.186 to 0.536); z = −0.74; p = 0.459). Within the comparison of the portable systems, no statistically significant difference was found concerning the accuracy of the facial models among scanning methods (p = 0.063). Overall, portable face-scan devices can be considered reliable for obtaining facial models. However, caution is needed when applying face-scanners with respect to scanning device settings, control of involuntary facial movements, landmark and facial region identifications, and scanning protocols.
