【摘要】 个性化服装CAD是服装CAD发展的新方向。本课题在分析个性化二维服装CAD和三维服装CAD技术国内外最新动向和发展趋势的基础上，提出个性化服装CAD理想系统的模型应该是融合二维和三维技术的综合体系，并向集成化、立体化、智能化和网络化的方向发展。本课题在探讨二维纸样设计技术和三维服装CAD造型技术的算法研究，并在两者结合的基础上开发出相对完整的个性化服装CAD系统。在此个性化服装CAD系统上我们首先引入三维人体模型，并将人体模型参数化，采用特征点和特征尺寸的对应关系，生成人体二维曲面，系统以这样的人体造型为基础，通过给定人体的特征尺寸以及服装款式，按照纸样放松量与服装空隙度的关系以及人体着装内空间的特点，计算出人体与服装间的偏离值，从而获得准确的服装特征点，以此拟合生成服装曲面，实现最佳服装造型。系统获得了符合个性化需求的服装造型之后，自动生成可直接用于服装制作的二维衣片纸样。本系统以人体的特征尺寸为纸样图样控制参数，按照纸样图形各特征点的计算公式进行参数化绘图，根据三维参数化人体变化后改变的特征尺寸自动换算直接得到相应改变的二维纸样。本课题建立包括导入三维人体模型特征化并生成二维人体图纸和二维个性化衣片纸样的相对完整的个性化服装系统，并对三维个性化服装的生成算法做了一定的研究和探讨。个性化服装系统是现在服装设计CAD的发展趋势，因此，课题的开发具有一定的理论意义和实际应用价值。更多还原

【Abstract】 It is becoming nowadays both industrial trends and academic research topics to develop personalized garment design system to the clothing industry. Based upon in-depth analysis of existing 2D and 3D CAD solutions for personalized garment design system, this thesis proposes innovative approaches by implementing and integrating both 2D and 3D modeling technologies along with application-specific algorithms into a unified system environmental, with potentials for future improvements in the areas of design tool integrations, 3D applications, support of artificial intelligence/expert systems, as well as internet-enabling readiness.This issue made a research on the subject in the 2D pattern design and 3D garment CAD modeling algorithm, and developed the individual garment CAD system on the basis of relative integrity combination of both.In this personalized garment CAD system, we first import 3D model of the human body and human model parameterization, a feature point and the size of the correspondence between the 2D human body surface, such a system based on the human form, given by the human dimension and clothing styles, and we achieve the best model. System was consistent with the individual demands of the garment modeling. Automatic generation can be directly used in the production of clothing 2D panels pattern. Of the system to the human dimension of the pattern design parameters, According to the graphic pattern characteristic point formula for the calculation of parameters of the mapping, 3D parametric changes in the human body after the change of feature size automatic conversion directly from the corresponding change in the 2D pattern.The topics include the establishment of the human body into 3D model of the characteristics of the human body and generate 2D and 2D drawings personalized panels depict the relative complete personalized clothing, as well as study on 3D personality of the clothing Algorithm. Personalized system is now garment design CAD development trend. Therefore this issue will lay theoretical and applied value for automatic garment design.更多还原
