摘要

为实现无实体楦基础的数字化量足制鞋，提出了基于非均匀有理B样条(NURBS)特征曲线自适应变形的个性化鞋楦定制系统，将足部NURBS特征曲线依据一定的舒适度规则变形成相应的鞋楦特征曲线来实现鞋楦定制。该系统采用切平面法获取足部的特征点、特征曲线和特征尺寸，重建出足部NURBS特征曲线。建立了足楦舒适度匹配规则，并根据变形方式及次序不同将特征曲线分为四种类型。以特征点、特征结点和特征尺寸作为约束，结合足楦舒适度规律驱动足部特征曲线自适应变形，生成相应的鞋楦特征曲线。最后，构建出鞋楦特征框架，通过特征曲线增添操作和曲面细分造型完成定制鞋楦的设计。给出了男士皮鞋鞋楦的设计实例和定制结果，定制时间在480 s内，定制的鞋楦美观大方。该系统具有实用性，且定制鞋楦的再设计利用率显著提高。

Abstract

To make customized shoes without standard shoe-lasts

a customized shoe-last system is established based on the adaptive deformation of Non-uniform Rational B Spline (NURBS) curves for foot characteristics. The system uses the deformation from foot characteristic curves to make shoe-lasts based on comfortable matching rules. First

the cutting plane method is used to acquire the characteristic information

including characteristic points

characteristic curves and characteristic sizes

following that

the characteristic curves are reconstructed in NURBS. Then

the comfortable matching rules between feet and shoe-lasts are established

and characteristic curves are divided into four different types according to different deformation ways and orders. Furthermore

the foot characteristic curves are deformed to shoe-lasts characteristic curves driven by the comfortable match rules in the constraints of the characteristic points

characteristic nodes and the characteristic sizes. Finally

it structures the shoe-lasts characteristic frame

and finishes the design of customized shoe-last through adding characteristic curves and subdividing the surface mesh of shoe-last. With this system

a mens leather shoe with comfort and beauty can be customized in less than 480 s. This system is practical

and can increase greatly the utilization of redesign for customized shoe-lasts.
