【摘要】 服装CAD技术是计算机科学技术在服装设计领域的重要应用。我国加入WTO后，中小型服装企业面临更多的机遇与挑战，竞争激烈，设计人员队伍流动大，影响服装品牌的建立。上海市科委项目——“服装加工公共服务平台”目的就是实现一个集设计、加工和服务于一体的统一资源信息共享平台，为中小型企业提供信息服务和网络化的智能款式设计。本文研究网络化环境下的面向非专业人员的智能服装款式设计系统。主要设计了系统的体系结构，对系统后台数据库设计和远程数据获取模块进行了详细分析，并给出了具体实现。 本文工作主要包括以下内容： 分析国内外服装CAD软件的现状和发展趋势，指出了服装款式设计CAD软件发展还不成熟的事实。结合国内服装生产市场现状，提出了开发网络化环境下的智能服装款式设计系统的必要性。 根据服装款式设计特点，将款式分割成若干部件，使款式设计过程简化为若干部件的拼接组合过程。采用三次B样条曲线和反算三次B样条曲线来构造款式部件的外轮廓；定义部件关键点支持部件的拼接；对构成智能款式设计的两大模块—款式输入模块和智能拼接模块，给出了设计要求和实现效果。 分析系统数据结构特点，提出了四层的款式部件数据库，把款式、部件、线、点四个层次密切联系。采用Oracle数据库平台，从需求分析到数据库实施，详细分析了数据库对象的创建，备份恢复和性能优化方案，使数据库结构更加合理，同时性能达到最佳。 面对款式设计的网络化要求，提出了两种实现远程数据获取的方法：基于Http方式，采用XML作为远程数据交换的格式，利用JSP构建服务器，在客户端使用ITC获取远程数据用MSXML解析，达到远程数据的正确获取和格式转换；基于SOAP和WebServices方式，利用WebServices提供远程方法调用来获取款式部件信息，在客户端采用SOAPToolkit获取数据后用MSXML解析，达到远程数据获取的目的。 服装加工公共服务平台项目的研究有利于推进中小型服装企业设计——加工——营销快速反应机制的发展。本课题的研究使在线化的智能款式设计成为可智能服装款式设计系统的数据库实现和远程数据获取能。本文提出的“基于部件拼接的智能款式设计”思路具有一定的创新性，后台大型数据库的设计管理和远程数据获取的多种实施手段，为网络化款式设计提供了基础。因此，本课题的开发具有一定的理论指导意义和实际应用价值。更多还原

【Abstract】 Fashion CAD technology is an important application of computer science and technology in fashion design realm. Since the entry of WTO of our country, middle or small scale fashion enterprise has encountered more opportunities and challenges. The fierce competition and the frequent fluxion of designers influence the establishment of fashion brand. The Shanghai Science and Technology committee’s project-fashion design and processing public service platform aims at providing a uniform resource and information sharable platform that is integrated with design, processing and service, at the same time, it will provide information service and intelligent style design based on Internet This essay focuses on the intelligent style design oriented to non-professional designers based on Internet It designs the structure of the system, and analyzes the background database design and remote data access module, the realization also been given.The main work of the essay contains:Through analyzing the current status and developing trend of fashion CAD software both domestic and abroad, it points out that the truth that fashion CAD software is far from mature. Combined with the domestic fashion production market status, it concludes it is essential to develop an intelligent fashion style design system based on Internet.According to the attributes of fashion design, fashion style can be divided into several fashion parts. The process of style design can be simplified as the combination of fashion parts. B-3 spline and reversed B-3 spline is adopted to construct the outer figure of fashion parts. The key points are also defined to support the rigging of fashion parts. The two main modules-style input module and the intelligent rigging module are also described in details.By analyzing the attributes of the system’s data structure, it puts forwards the four-layered fashion style parts database, which links style, part, line, point together.Using Oracle as the database platform, it introduces the construction of all database objects, including the backup, restore and performance tuning solutions. So it will make the structure reasonable and the performance optimal.To reply the Internet demand of style design, it draws two methods of remote data access: One is based on Http, the data format is XML, the web server is constructed by JSP, the ITC can obtain the data and parse it by MSXML, so that it can reach the appropriate data access and format conversion. The other is based On SOAP and WebServices, the WebServices can provide remote procedure call to obtain the fashion parts information. In the client, SOAP Toolkit can obtain the data and process itThe research of fashion design and processing public service platform will help to accelerate the fashion enterprise design- processing-sales quick response mechanism. It also make the on line intelligent fashion style design possible. The method of intelligent fashion style design is innovative. The configuration and management of large background database and the multiple methods of remote data access will put a solid foundation for fashion style based on Internet. So it has both the theoretical and practical value.更多还原
