Three-dimensional (3D) body scanning technology has applications for obtaining anthropometric data in human-centered and product development fields. The reliability of 3D measurements gathered from 3D scans must be assessed to understand the degree to which this technology is appropriate for use in place of manual anthropometric methods. The intra- and inter-rater reliabilities of 3D facial measurements were assessed among four novice raters using 3D landmarking. Intraclass correlation coefficient (ICC) statistics were calculated for the 3D measurement data collected in three phases to assess baseline reliabilities and improvements in reliabilities as the result of additional training and experience. Based on the results of this study, the researchers found that the collection of 3D measurement data, by multiple raters and using 3D landmarking methods, yielded a high percentage of ICC statistics in the good to excellent (>0.75 ICC) reliability range. Rater training and experience were important considerations in improving intra- and inter-rater reliabilities.

三维（3D）人体扫描技术在以人为本和产品开发领域中具有获取人体测量数据的应用。必须评估从 3D 扫描收集的 3D 测量结果的可靠性，以了解该技术在何种程度上适合替代手动人体测量方法。使用 3D 地标在四名新手评估者中评估了 3D 面部测量的内部和评估者间可靠性。对三个阶段收集的 3D 测量数据计算组内相关系数 (ICC) 统计数据，以评估基线可靠性以及额外培训和经验带来的可靠性改进。根据这项研究的结果，研究人员发现，由多个评估者并使用 3D 标志方法收集 3D 测量数据，产生了很高比例的 ICC 统计数据，其可靠性范围处于良好到优秀（>0.75 ICC）。评估者培训和经验是提高评估者内部和评估者之间可靠性的重要考虑因素。
