脚型三维测量与特征参数自动提取

3 D measurement and feature parameters automatic extraction of foot

脚型自动测量的目的是提取与制鞋相关的特征参数,并用这些特征参数指导鞋楦的设计,制造出合脚的鞋.使用脚型三维扫描仪,获得了脚的三维数字模型.详细描述了主要特征参数的定义,提出了在未做标记的情况下特征参数的提取方法,结合实际脚型测量给出了测量结果.特征参数的自动提取可为个体化鞋楦的设计和量脚制鞋提供必要的数据支持.

The purpose of 3D measurement of foot is to extract feature parameters related with shoe manufacture and guide last design and manufacture for a pair of fit shoes.The 3D shape of foot is measured by 3D foot scanner.The main feature parameters are investigated in detail and a method to extract feature parameters for the foot without tag is presented.Extracted result is obtained with the real foot measurement.Automatic extraction of feature parameters can provide data support for individual last design and customization shoe manufacture.
