【摘要】 为探究人体测量中三维数据与手工数据间的一致性和可替换性,及不同扫描仪所得结果间的数据等价性,利用HumanSolutions和[TC]~2 2种三维扫描仪分别对20～35周岁的女性样本人体进行扫描,通过逆向工程软件手动测量388个样本的30项身体特征尺寸。对比2组三维数据与其对应手工数据的折线图,利用组内相关系数对数据的一致性进行探究;依据国标对三维数据与手工数据间的可替换性进行讨论和判别;以手工数据为媒介,对比2种三维数据与真实值间的一致性和可替换性,判断不同扫描仪数据结果的等价性。结果表明:2种仪器所得数据与手工数据间存在较好的一致性,组内相关系数大于0.75,3种数据在部分测量项上具有较好的可替换性,进行数据处理和分析时可等价使用。更多还原

【Abstract】 In order to explore consistency and substitutability between human data results obtained by three-dimensional(3-D) scanners and manual data as well as the data equivalence between the results obtained by different scanners, this paper used HumanSolutions and [TC]~2 3-D scanners to scan the samples of women between the ages of 20-35, and 30 somatotype indexes of 388 samples were manually measured by Rapidform XOR3. The consistency of the 3-D data and their corresponding manual data were checked using line chart and intraclass correlation coefficient(abbreviate it to ICC). The replaceability of the data were checked according to the national standard. With manual data as a medium, the data consistency and replaceability between two kinds of 3-D data and the real size value were compared to judge the equivalence of different 3-D data. The results show that good consistency exists between 3-D data and manual data(ICC>0.75), and the three data of Human Solutions 3-D scan, [TC]~2 3-D scanning and manual measurement are replaceable on partial measurement terms, and can be used equivalently in data processing and analysis.更多还原
