【摘要】：云锦作为世界非物质文化遗产,以其精湛工艺和精美设计闻名世界。由于云锦织造工艺复杂且大量采用金线和孔雀羽毛等昂贵材料,导致传统设计的打样周期过长、效率低下和成本过高,利用数字化展示技术能有效地解决这一问题。而当前织物数字化展示技术只是纺织CAD的附加功能,不能从设计者的角度有效提高织物的设计效率。本课题对云锦织物数字化展示技术进行了研究,基于web平台并结合二维模拟及三维场景模拟技术,实现了可靠的数字化展示,减少试样次数,从而提高了云锦的设计效率。云锦织物数字化展示系统分为如下三个模块:1)通过云锦图像采集、组织区域自定位、组织预处理和改进的K-means聚类算法,得到云锦组织结构分离图;2)提出了基于云锦织物组织结构和颜色索引模式的织物模拟方法,抛弃了传统纱线建模的织物模拟的方法,使用Phong光照模型,利用图像插值的纹理映射技术和亮度融合算法,使云锦织物二维模拟效果更加具有真实感;3)采用基于WebGL三维场景模拟技术,通过Three.js库实现外部模型加载、场景控制、纹理材质贴图、光照模型添加,模型压缩优化和浏览器的渲染,实现了云锦织物的三维场景模拟。该展示系统采用基于HTML5的网站式交互,给用户提供了优秀的人机交互和视觉感,也便于后期工程师的维护和改进。本系统已经投入运行使用,有效地降低了云锦产品的推广和销售成本,能给企业带来可观的经济效益。
[Abstract]:As a world intangible cultural heritage, Yunjin is famous all over the world for its exquisite craftsmanship and exquisite design. Because of the complexity of brocade weaving technology and the large use of expensive materials such as gold thread and peacock feather, the traditional design has long proofing cycle, low efficiency and high cost. This problem can be effectively solved by using digital display technology. At present, the technology of fabric digital display is only the additional function of textile CAD, and it can not effectively improve the design efficiency of fabric from the point of view of designer. In this paper, the digital display technology of brocade fabric is studied. Based on web platform and combined with 2D simulation and 3D scene simulation technology, reliable digital display is realized, the number of samples is reduced, and the design efficiency of brocade is improved. The digital display system of brocade fabric is divided into the following three modules: 1) through the image collection of brocade, the self-localization of the organization area, the pre-processing of the organization and the improved K-means clustering algorithm, The fabric simulation method based on the pattern of fabric structure and color index is put forward. The method of fabric simulation based on traditional yarn modeling is abandoned and Phong illumination model is used. The texture mapping technique of image interpolation and brightness fusion algorithm are used to make the two-dimensional simulation effect of Yunjin fabric more realistic. The 3D scene simulation technology based on WebGL is used to realize external model loading and scene control through Three.js library. Texture mapping, illumination model adding, model compression optimization and browser rendering, the 3D scene simulation of brocade fabric is realized. The display system uses HTML5 based website interaction, which provides users with excellent human-computer interaction and visual sense. It is also convenient for later engineers to maintain and improve. The system has been put into operation, effectively reducing the promotion and sales costs of Yunjin products, and can bring considerable economic benefits to enterprises.
