摘要
为普及三维人体测量技术,以胸围为研究对象,采用手工测量与三维人体测量(以Sizestream扫描仪为例)两种方法获取胸围测量值,运用Excel、SPSS软件对两组测量值进行分析。研究发现,手工测量与三维人体扫描仪测量数值间存在显著相关性,且三维人体扫描仪测量的数值拥有更高的稳定性。因此,两种测量方法的数据x、y间可建立转换模型(x为手工测量值,y为三维扫描仪测量值)。对数据组分别进行线性函数、二次多项式、S形曲线、复合函数、指数函数和逻辑函数拟合,最终选出的最优化拟合函数模型为y=1.006x+4.540。
In order to popularize the three- dimensional body scanning technology, chest circumference was measured manually and with 3D body scanning technology (a case study of Sizestream scanner) respectively. By analyzing the two groups of measured values with Excel and SPSS,it was found that there was an obvious correlation between these 2 groups of values, of which the one acquired from 3D body scanning was more stable. In view of this,a conversion model was established with the values from manual measurement as x and the ones from 3D body scanning as y. By fitting the values of the 2 groups respectively with linear function,quadratic polynomial,s- shaped curve,composite function,exponential function and logical function,the optimal fitting function model finally selected is y=1.006 x+4.540.
