人体与服装特征曲面间面积松量的分配关系

Area ease distribution relationship between the body and garment

采用人体扫描仪得到标准人体和同一款式不同放松量服装的点云数据,采用最小二乘法和三次多项式分段拟合不同部位截面的曲线以及弧长等分计算曲线等分点,建立人体与服装间面积的算法模型。讨论不同人体特征曲面随人体角度变化、人体与服装间面积松量的分配关系,揭示人体穿着服装空间的变化规律。可为服装研究领域提供人体与服装之间真实的空间松量分配关系,实现客观评价服装外观差异,改善服装合体性,为三维服装虚拟效果提供检验标准的目标。

In accordance with the clouds data of the standard body and various garment sizes of a specific style using the 3-D scanner,the curves of the cross sections of different parts are fitted using least square method and cubic polynomial functions,the co-ordinations of points that divide curve by even arc length are calculated,algorithm model of the area ease between the body and garment is built.This article discusses the distribution relationship of area ease between the body and garment as changing with body angles and exposes the change rule of vacant area between the body and garment.It has provided the real ease distribution relationship between the body and garment for the garment manufacturing sector,realized objective evaluation of the differences of garment appearance,improved the fit of garment,and offered a testing standard for checking the effect of 3-D simulation of the garment.
