个性化三维虚拟试衣系统研究

为满足用户对虚拟试衣的个性化需求和提高虚拟试衣体验,提出一种包括自动化蒙皮、基于单张图片人脸三维自动重建、人体参数化变形以及服装模型穿透处理等模块的个性化虚拟试衣系统。设计了自动化蒙皮算法,解决已有虚拟试衣服装模型制作成本高的问题;通过基于单张图片的三维人脸自动重建和人体参数化变形,满足消费者个性化需求;运用基于自动透明贴图计算的服装穿透处理方法,改进系统试衣效果。实验表明,所提出的系统能够以较低的构建与运行成本实现较好的试衣效果,提供良好的个性化虚拟试衣体验。

Research on Personalized 3D Virtual Try-on System

In order to satisfy the user’s personalized demands and improve the virtual try-on experience, a personalized virtual try-on system is proposed, which includes auto-skinning, 3D face reconstruction based on a single image, parametric deformation of human body and penetration processing of garment model. Firstly, auto-skinning algorithm is designed with the aim to reduce the cost of making garment models for the existing virtual try-on systems. Secondly, individual needs of the customers can be met with a single image based automatic 3D face reconstruction and parametric deformation of human body. What’s more, on the basis of automatic calculation of transparent textures, cloth penetration is solved to improve fitting effects of the system. According to the experiments, the virtual try-on system introduced in this paper is able to achieve better fitting effects with lower construction and operation costs, in which case good personalized experience of virtual try-on is provided.
