Abstract: The automobile is taken as an example, the basis of the automatic style computation technology - the automatic segmentation and recognition of the product shape characteristics is studied. From the perspective of style innovation, three key classes which are closely related to characteristics recognition are defined. Based on the key classes, the mapping between the key feature points set and the car assembly set, as well as the mapping between the car assembly set and the vehicle type set are defined. On this basis, a recognition model about automobile shape characteristics recognition and put forward a few recognition algorithm samples are given, including the key feature points extraction algorithm, the car assembly set segmentation algorithm and the vehicle type recognition algorithm. At last, a prototype system about the recognition method is introduced.

Key words: Automobile recognition, Innovation design, Key classes set, Product style
