智能三维虚拟试衣模特仿真系统设计* 摘要:针对服装物理仿真通常计算量庞大、在低端硬件平台或交互式环境进行高质量模拟的挑战,将人工生 命思想引入服装纹理生成,基于混合虚拟现实技术研究开发了智能三维虚拟试衣模特仿真系统。通过在三维空 间中构建与真实人体类似的三维虚拟模特作为消费者的试穿替身,同时设计实现了场景屏风功能,这样不但便 于根据着装场合自由切换服装纹理,而且可以让消费者通过这一虚拟平台更为直观、自由地观察着装效果为了 使三维试衣系统更为智能化,还建立了服装搭配合适度智能评价系统。 关键词:虚拟试衣模特;人工生命;混合虚拟现实技术 引言 近几年,虚拟服装是虚拟现实和计算机图形学领域的研究 热点之一,国外的服装电子商务发展较早,不少服装网站已能 提供产品的三维视图、购买历史记录、虚拟试衣间及配套设施 等多种服务。例如著名的试衣网站MyVirtuaMl odel就提供了 进行人体测量的网上试衣服务[1];德国弗劳恩霍夫学会的科 学家与其他科研小组共同开发出一套试衣系统[2]。 相对于国外试衣系统,国内相关研究也取得了一定的进 展。近期代表性的研究包括:文献[3]介绍了虚拟服装的发展 历史和现状,并着重了介绍当前各个研究机构的研究工作;文 献[4]通过分析服装虚拟仿真的基本步骤,给出了改进的质 点—弹簧模型和服装真实感模拟方程,并对动态系统进行了求 解;文献[5]对虚拟人动画中的三维服装仿真技术进行了研 究,包括虚拟人体建模、角色动画、布料物理模拟以及可变形体 碰撞检测与响应,总体目标是构建一个完整的三维服装仿真环 境,并且围绕系统实时性能完成高效算法的开发。纵观虚拟服装的研究现状,主要集中在四个方面: a)参数 化人体形态建模问题; b)三维服装动态展示提供角色动画持问题; c)布料物理建模的计算效率和真实感问题; d)实时交 互性问题。服装物理仿真通常计算量庞大,如何在低端硬件平 台或交互式环境(如普通PC或视频游戏)进行高质量模拟是 一个新的挑战[6]。本文将人工生命思想引入进服装纹理生 成,基于混合虚拟现实技术研究开发了智能三维虚拟试衣模特 仿真系统,通过在三维空间中构建与真实人体类似的三维虚拟 模特作为消费者的试穿替身,同时设计实现了场景屏风功能, 可让消费者通过这一虚拟平台更为直观、自由地观察着装 效果。 1 系统总体设计 1·1 系统框架结构 网络虚拟服装协同设计系统的总体框架结构如图1所示。 整个系统包括模型生成、场景设置、人工纹理、3D渲染四个部 分。其中,模型生成包括三维建模、模型参数选择、导入模型三 个部分;场景设置包括场景导入和光照选择两个部分。系统首 先进行三维人体的建模,并根据模型特征的不同保存多个副 本;然后根据用户的参数选择从中选择合适的模型导入系统 中;之后系统根据用户的选择设置好场景;最后, 3D渲染将人 体模型和试衣场景显示在屏幕上。 2 系统流程 根据系统框架,程序被分成三个模块来实现。模型导入模 块首先接收用户输入控制模块传来的选择参数,然后根据选择 参数分析并导入Maya生成相应的模型文件( x文件),在系统 中创建相应的模型对象。场景生成模块首先接收用户输入控 制模块传来的参数,之后生成特定的场景图片。最后,系统将 模型导入模块生成的模型对象和场景生成模块生成的场景对 象一起显示出来。系统设计流程如图2所示。

Abstract :The non-material cultural heritage is passed in various national peoples from generation to generation,and regarded as constituent of each traditional culture manifestation of their cultural heritage , as well as traditional culture manifestation related material object and The non-material cultural heritage is an important componentthe of traditional culture , and it is various national peoples’ wisdom The protection to the non-material cultural heritage satisfies the dissemination of bringing honor to and inheriting our country glorious history The present non-material cultural heritage guard mode tradition is unitary,and seems insufficient to the non-material cultural heritage's Introducing the high tech method into the non-material cultural heritage's protection is a nice protective device to rich non-material cultural heritage ,to raise the non-material cultural heritage protection level, and to inherit the non-material cultural heritage On the foundation of previously researches,this article has conducted the research to the high tech in the non-material cultural heritage's application with existing high tech It has elaborated on the application prospects of traditional film and television technology, the digital multimedia technologies, the movement capture technology, the three dimensional animation technology, the 3D film and television technology, the 180-degree movies, the virtual reality technology, the modern process technology and the landscape regeneration technology in the protection of non-material cultural And this article has carried on a discussion on the high tech application to the protection of the Wuyuan main non-material cultural heritage——anhui opera, the exorcism dance, the she xian inkstone and three carves Key words: High tech; Non-material cultural heritage; Protection; Application ; Wuyuan
