面向高级定制的个性化虚拟服装展示

Personalized virtual fashion show for haute couture

虚拟服装展示为线下服装订货会和时装秀提供了线上解决方案,打破了空间的局限性,为企业和用户提供更方便、有效的服装试穿新方式。针对现有的大多数虚拟试衣系统存在体形尺寸和展示效果单一、无法满足高级定制用户个性化精细要求的问题,研发了一个基于服装自适应变形的个性化虚拟服装展示系统。首先,建立基于人体体形参数的三维人体重建框架;然后,采用混合蒙皮算法建立人体模型顶点和三维服装顶点的联系;最后,对对偶四元数进行插值,实现人体变形驱动服装变形,完成服装的自适应调整。并基于Unity平台开发了一款面向高级定制的虚拟服装展示系统,以检验相关算法的应用效果。

Virtual garment display provides an online solution for offline apparel ordering meetings and fashion shows,alleviating the limitations of space and providing a convenient and effective new way for companies and users to try on clothes.To address the problem that most of the existing virtual clothing fitting systems are unable to generate personalized clothing effect of the customers due to the preset uniform body size and display effect,a personalized virtual clothing demonstration system with automatic garment adaption is developed.Our approach is mainly divided into three steps:first,a three-dimensional human body reconstruction framework based on human body size parameters is set up.Then the relationship between the mannequin vertex and the three-dimensional garment vertex is established using mesh skinning.Automatic garment adaption is finally realized by driving the garment deformation according to human body deformation using dual quaternion interpolation.A VR-based system for clothing display is developed for general users using Unity 3D to validate the presented method.
