基于意象认知模型的汽车草图设计技术研究

产品意象认知模型阐明了消费者情感需求与产品造型之间的关系.运用专家访谈、影响汽车外观造型特征的眼部跟踪观察实验、影响产品意象认知的造型特征提取实验、关键造型特征与产品意象认知关系之量化实验等多实验的方法，建立了基于特征匹配的产品意象认知模型.基于该意象认知模型，开发了汽车草图设计原型系统，消费者只要输入意象词汇，就可以得到一组具有该意象的草图设计方案；设计师在计算机中描绘简单的造型特征，系统就可以自动给出该草图相应的意象.

Research on automobile sketch design based on image cognition model

Product image cognitive model clarifier the relation between customers' emotional needs and product form.This is the first time to use the multi-experiment method to create the product image cognition model based on feature-matching,such as experts visit,eye track observing experiments influencing the car's appearance features,the features extraction experiments influencing product image cognition,the quantitative relation experiments between key formal features and product image cognition.The computer-aided automobile sketch design system based on image cognition model was implemented.Through this system,customers could input the image words to get the related conceptual design sketches.Designers could make a sketch of simple formal features in the computers and the system would automatically bring forward the image corresponding to the sketch.
