网上3D试衣系统技术研究

虚拟试衣系统是一种应用于服装电子商务的实时交互平台。为了满足虚拟试衣系统真实性、实时性、方便性等设计要求,该文采用服装操控技术为虚拟服装建立三维模型,并把其中的交互建模标记绑定到服装模型上,以此取代手工指定的标记,从而把原来需要人机交互的三维服装建模过程转化成一个后台计算过程。保留服装操控技术中的表面拖曳交互机制,作为用户对建模完成之后的虚拟服装的微调手段,并把原来需要人机交互指定的拖曳不动点信息固化到服装模型数据文件,以此提高虚拟试衣间实际应用中的方便性。在网上3D试衣系统的设计中,提出了布片无缝拼接算法以及二面角调整算法,并在实验中取得了较好的效果。

Research on Technique of Net-based 3D Fitting Room

Virtual fitting room is a realtime interactive platform used in electronic business affairs of garments.The technique of clothing manipulation upon the 3D virtual clothing modeling is applied to meet the realistical,realtime and convenient design demands of virtual fitting room.The manual marks are replaced with the prearranged information binding to the clothing model,so that the 3D clothing modeling interactive process is changed into a background computing process.The surface dragging interactive process of clothing manipulation is remained as a method of little adjustment to the virtual clothing after modeling.The immobile vertexes formerly pointed via an interactive process are solidified into clothing model data files,so that the convenience of virtual fitting room is improved.An algorithm of integral linking of cloth slices and an algorithm of dihedral angel adjustment are advanced during the implementation of net-based 3D fitting room system,and they are proved by satisfactory results of experiments.
