基于局部特征的青年女性腿部形态分类

为提高女性裤装的合体性与舒适性,采用三维测量法、图像测量法及手工测量法相结合的方式,对236名18~25岁的青年女性腿部形态进行测量,获取20个相关特征变量;通过主成分因子分析得到影响腿部形态的主要特征因子,通过聚类分析得到青年女性腿部形态的分类结果;最后结合膝曲角的正负归纳出各类腿部形态的辨别规则并进行辨别验证。研究得出:影响腿部形态的主要特征因子有水平围度因子、长度因子、小腿围度差因子、腿部曲度因子、腿部轮廓因子和大腿围度差因子;人体腿部形态可分成圆体型、稍扁体型和扁体型3类;以大腿宽厚比、大腿根围膝围比、大小腿长比及膝曲角4个变量建立腿部形态分类规则。

Leg classification for young women based on leg shape characteristics

In order to improve the fit and comfort of women's trousers, body classification for young women was studied and discussed according to the characteristics of leg shapes. Using three-dimensional human body scanning, image measurement and manual measurement, leg shape of 236 young women aged between 18 and 25 years were measured, and twenty characteristic parameters describing leg shape were obtained. The main characteristic factors affecting leg shape were concluded by component factor analysis, and the classification results of young women's legs were extracted by using cluster analysis. Combining with the values of knee angle, the identification rules of each leg shape category were established and the new samples were classified and verified. Consequently, the main characteristic factors that affect the leg shape were the horizontal girth, the length, the calf girth difference, the leg curvature, the leg contour, and the thigh girth difference. The leg shape was divided into three categories, i.e. round, slightly flat and flat, and the identification rules of each leg shape category were established with four variables.
