【摘要】：针对基于特征的参数化人体造型方法在变形精度和个性化表现方面存在的问题,在深入分析人体部位造型和变化特点的基础上,提出一种新型的参数化人体造型和变形算法。首先,利用水平剖面横切获取人体模型的特征腰围围线,并引入人体特征尺寸参量,确定腰围围线上正面、背面和侧面的3个迭代初始轴和初始值;然后,利用角度加权平均计算出围线上各点的坐标,通过不断迭代实现腰围围线的变形;最后,在指定变形区内,根据其他相关围线的高度和腰围围线初始值,确定这些围线的迭代初始值,实现指定区域的其他围线变形,完成该区域的整体变形。研究结果表明,该数字化人体模型可依据指定特征尺寸,变形得到个性化人体模型。
[Abstract]:According to the parametric human modeling method based on features of deformation in precision and personalized performance problems, based on analyzing the human body shape and change characteristics, proposes a new parameterized human body modeling and deformation algorithm. Firstly, get the characteristics of waist people model with horizontal section transverse contour, and the introduction of human body the feature size parameters, determine the waist line around the front and back side of the 3 axis and the initial iteration initial value; then, using the angle weighted average calculated coordinates of the points on the circumference, through the iterative implementation of waist circumference line deformation; finally, specified in the deformation zone, according to the height and other related waist girth the contour of the initial value, determine the contour of initial iterative values, to achieve the designated area of the other contour deformation, the deformation of the complete region. The results show that the digital human body The model can be deformed according to the specified feature size, and the individual human body model can be obtained.
