| 摘 要： | 目的检验面部软组织三维测量系统的技术可靠性.方法以石膏头像为研究对象,用系统在15种不同条件下测量模型面部9个点至鼻根点的距离,以用游标卡尺得到的测量结果为评判标准与前者比较.结果两者的平均差值为1.21mm,误差率为2.08%.模拟头位变化的8种状态中,仅在右转10°时与标准相比有显著性差异.结论系统的测量误差达到人体测量手册的要求.

| Abstract: | OBJECTIVE: To test the validation of the 3D measuring technique. METHODS: A life-size plaster cast of human head was used as the anthropomorphic model. Fifteen experimental conditions were studied. Nine linear distances between landmarks and Nasion were measured each time. These were compared to the standard anthropometric measurements using the same landmarks. RESULTS: The mean difference was 1.21mm (2.09%). Among the 8 conditions imitating different head posture,only the one turning 10 degrees to the left had a significant difference from the normal position. CONCLUSION: In accordance with the requirements of " human measurement handbook", the system error is acceptable. |
