【摘要】：随着技术的迅速发展和市场竞争的愈发激烈,产品设计和开发的方式各不相同,仅仅符合产品使用功能远不能满足消费者的需求,能够了解消费者的产品喜好以及帮助他们建立更加愉悦的产品造型是设计师和制造商面临的新挑战。对此,产品的造型在调动消费者情感上占据了非常重要的地位。关于产品造型及意象的研究,也受到了国内外学者的普遍关注。本研究以意象产品形态出发,分析了消费者对于产品造型形态所形成的感性意象,运用球面调和映射的分析方法,提出了一种丰富产品形态的新方法。本研究一共包含三个阶段：第一,运用感性工学方法提取样本及感性意象,并利用主成分分析法建立消费者感性意象与产品三维形态之间的关联程度,创建样本意象尺度分布图,确定实验样本形态；第二,采用三维工程软件对确定的样本进行三维模型的建立,对其进行三角网格划分,提取网格化模型的表面数据结构,运用球面调和映射的分析方法对网格化的三维模型表面进行球面参数化,使之生成球面嵌入体模型,并对球面参数化数据进行提取；第三,运用得到的球面嵌入体模型,建立两种不同产品三维形态表面上各个点的对应关系,利用线性插值方法得到更多的融合产品形态,设计计算机图形用户界面对融合产品的三维形态进行展示,分析融合产品形态所包含的意象,对本研究的创新点进行论证。选取两个不同形态的汽车车身模型为实例进行研究,结果表明该方法对于产品形态的融合具有很好的适用性,在计算机辅助产品形态造型设计中将具有良好的应用前景。
[Abstract]:With the rapid development of technology and the increasingly fierce market competition, the ways of product design and development are different. It is a new challenge for designers and manufacturers to understand consumers' product preferences and help them to establish more pleasant product modeling, which can only meet the needs of consumers. In this regard, the product modeling in the mobilization of consumer emotion occupies a very important position. The research on product modeling and image has also been widely concerned by scholars at home and abroad. Based on the image product form, this paper analyzes the perceptual image formed by consumers' product modeling form, and puts forward a new method to enrich the product form by using the analysis method of spherical harmonic mapping. This study consists of three stages: first, the perceptual engineering method is used to extract samples and perceptual images, and the principal component analysis is used to establish the correlation degree between consumer perceptual images and three-dimensional morphology of products, and the scale distribution map of sample images is created to determine the experimental sample morphology. Secondly, the 3D model of the determined sample is established by using 3D engineering software, and the surface data structure of the gridding model is extracted, and the spherical inlay model is generated by using the spherical harmonic mapping analysis method to generate the spherical inlay model and extract the spherical parametric data. Thirdly, the corresponding relationship of each point on the surface of two different products is established by using the spherical embedded body model, more fusion product forms are obtained by using linear interpolation method, the computer graphic user interface is designed to display the three-dimensional shape of the fusion product, the images contained in the fusion product form are analyzed, and the innovation points of this study are demonstrated. Two automobile body models with different shapes are selected as examples to study. The results show that this method has good applicability to the fusion of product morphology and will have a good application prospect in computer aided product shape modeling design.
