| 摘 要： | 介绍了一种从二维形状信息获取三维个性脚型的方法.首先通过扫描仪获取50位参与者的脚型样本,平均各样本顶点坐标构建标准脚型.利用特定脚型的正、侧面轮廓信息作为约束条件,采用离散Laplacian坐标线性求解系统对标准脚型进行变形,获得个性化的三维脚型.利用20位参与者的数字脚型对该方法进行检验,结果证明,该方法是有效的,其平均误差为1.03mm.方法可在不用扫描实际脚型的前提下用于鞋楦定制,实现鞋子的个性化定制.

| Abstract: | A novel method to generate an individual 3D foot shape from 2D dimensions is proposed.A standard foot shape(template)was first defined as the average shape from foot data samples of 50 participants.Front and profile contour information of specific foot shape are taken as constrained condition.Standard foot shape is deformed by using discrete Laplacian coordinates linear solving system and then we obtain the indivdiuation 3D foot shape.We used twenty participants' digital foot shape to test this method,and t... |
