Research on the Style of Product Shape Based on NURBS Curve

摘要

To further study on the relationship between users' perception of style image and product shape features, a research method of product feature image based on the NURBS curve was proposed. The experimental study was conducted with the example of goblet. Firstly, the key control points impacting the shape features were extracted and a plurality of products 3D models were constructed. Secondly, five representative products and three key images were selected by the methods of hierarchical clustering and factor analysis. Then, the Kansei Engineering evaluation system of goblet was established, with which the subjects conducted Semantic Differential experiment for a thirty-three products with different shapes, and the data were analyzed by multiple regression analysis as well. Finally, the mapping model between the control points and Kansei images was constructed and its reliability was verified. This mapping model accurately reflected the relationship between the various control points and different style images, this research method can be applied to the modelling design of other products, which can help the designers grasp the product style accurately. This paper would play an important guiding role on product development and creative design.
