摘要：

为解决个性化的服装样板生成技术中合体性的问题,提出了一种基于三维测量数据的个性化女上装原型样板的生成方法。首先,随机选取1名青年女性进行三维人体扫描,根据人体特征点将三维扫描模型于东丽Creacompo Ⅱ Torso系统中数字人台进行拟合,以得到个性化的数字人台模型。采用该软件对个性化数字人台模型的特征线进行分割和展平,得到二维展平矢量图,并根据二维矢量展平图建立了原型样板的变化规则。最后将原型样衣进行试穿实验,生成的个性化原型能够良好地展现实验对象的躯干形态,验证了样板生成规则的可行性和合体性,为个性化女装样板生成提供了一种新的途径,丰富了三维人体模型的二维原型生成的理论和实践。

Abstract:

In order to solve the problem of fitness in personalized pattern technology, a new method to generate personalized female's prototype based on three-dimensional measurement was proposed. Firstly, a female with standard stature was randomly selected and the body size was scanned. Then, the three-dimensional body model was fitted with digital mannequin based on the rule of the body feature points to obtain the personalized digital mannequin. The digital mannequin was from Creacompo Ⅱ Torso in TORAY software system. Next, the TORAY software was adopted to divide and flatten the digital human mannequin referring to the feature lines and the flattening vector graph was obtained later. Finally the rules of the personalized female prototype was established according to two-dimensional flattening vector graphs. The personalized prototype was tested well display and verified the feasibility of this prototype generation method. This study provides an effective measure for the generation of personalized female's pattern, which also enrich the theory of the two-dimensional prototype generation from three-dimensional human model.

Key words: personaliztion, female prototype, 3-D human model, digital mannequin, surface flattening
