【摘要】 目前,三维服装CAD技术正处在不断研制开发阶段,一般主要包括三大内容:二维衣片到三维衣片的转换;模特的动态效果显示;三维服装的动态效果显示。二维服装样版至三维效果显示可以避免必须缝制样衣后才能观察其效果的限制,克服了盲目性和滞后性。而效果显示程度的评价与掌握,这将是三维系统完善与否、好用与否的关键一环。 本文以上海市教委重点学科建设“服装设计与信息数字化研究”项目为背景,从人体和服装之间的不同空隙量入手分析,从服装的静态和动态综合效果出发进行研究,拟对二维样版到三维立体展示系统进行完善,设计一个服装合体性的评价系统。 首先对实验方案进行了设计并实施,本文基于点、线、面的原理,自制了一个测量人体和服装横截面的工具(截面曲线测绘台)。用该工具测量人台与12件样衣的横截面,运用MATLAB软件,采用三次样条曲线的拟合方法对人台和服装的胸围、腰围的横截面进行拟合,从而获得服装和人台之间的空隙量。 通过人体穿着实验对服装的合体性、美观性、运动舒适性进行评价,建立主观评价体系。更多还原

【Abstract】 Now, 3D clothing CAD technology is being developed. Generally, it includes three contents: the transform of 2D pattern to 3D clothing;the dynamic show of model;the dynamic show of 3D clothing. Using the system of 2D pattern to 3D show can avoid making the clothing sample to evaluate the 3D effect. But evaluating and grasping the degree of effect are one of keys which judge whether the system is good or not, perfect or not.Based on the project "fashion design and digital research", this paper analyzed the different gaps between body and dress, studied the static and dynamic comprehensive effects of dress, made the system of 2D pattern to 3D show to be better and more perfect and designed a fitness evaluation system.First, designed and carried out the experiment plans, the author designed and made an instrument of measuring the horizontal cross section of body and dress. Through measuring the horizontal crosssection of body and dress, applying the MATLAB software and using the SPLINE curve to fit the horizontal cross section curve of body and dress, obtained the gaps between body and dress.Designed wearing experiment to evaluate the fitness, beauty and comfort and established the subjective evaluation system.Then analyzed the data from the two experiments above, established the regression models between subjective feeling values and eases allowances, between eases allowances and gaps, between gaps and subjective feeling values. Using the eases allowances and gaps expresses the subjective evaluation models.In order to solve the contradiction between the complication of the evaluation system and the. desire of accurate result, fuzzy comprehensive evaluation model is applied to evaluate the dynamic and static effect of clothing.Last, designed and compiled the evaluation module of 2D pattern to 3D show.The results of the thesis are the extension of 3D clothing CAD, meeting with the market. The evaluation system makes the experts’ knowledge to share, so more and more people can use the 3D virtual clothing system better. It also improves the efficient of designer and the enterprises’ economic benefits. So the thesis hasadvance and realistic significance.Zhao Suqing(Fashion Design and Engineering) Supervised by Professor Zhang Zufang更多还原
