虚拟试鞋关键技术研究与实现

Research and Implementation of Key Technology of Virtual Shoe Test

为了解决消费者线上购鞋时因无法试穿导致的鞋不合脚问题,结合数据库及计算机图形学相关知识,对虚拟试鞋关键技术进行了研究与实现。首先,构建数据库,用以存储鞋、鞋楦及脚模型数据,对各类数据进行安全有效的管理;其次,从合脚性以及透气性两方面对鞋靴舒适度评估进行了研究,提出了一种提基于部分OBB包围盒与平面拟合相结合的数据提取算法,使得合脚性的评估更加准确;最后,以脚底面为基准,结合OpenGL图形库与鼠标控制,实现了交互式试鞋。为虚拟试鞋的实现提供理论支持。

In order to solve the problem of uncomfortably wearing shoes caused by no trial wear in the process of online shopping for shoes by consumers,the key technologies of virtual test shoes are studied and realized based on the knowledge of database and computer graphics.First of all,build a database to store shoe,shoe last and foot model data,all kinds of data for safe and effective management;secondly,the comfort evaluation of shoes and boots is studied from the aspects of foot fit and air permeability in this paper,and a data extraction algorithm based on the combination of partial OBB bounding box and plane fitting is proposed to make the foot fit evaluation more accurate.Finally,based on the bottom of the foot,combined with OpenGL graphics library and mouse control,the interactive shoe test is realized,which provides theoretical support for the realization of virtual shoe test.
