| Abstract: |
| The work aims to carry out the image styling and form coupling optimization design for the prototype form of the product, so as to make the product prototype design in line with the consumer's perceptual cognition and emotional needs. Firstly, the prototype experiment was carried out based on product prototype theory. Then, the form blending algorithm of NURBS curve with minimum distance was adopted to fuse and homogenize the product prototype and image prototype. Next, the spectrum analy-sis method was applied to quantify the form characteristics of the product. The form coupling degree was calculated by cosine sim-ilarity, and the form coupling mechanism was analyzed by combining consumer's image evaluation value and form preference de-gree. Finally, the genetic algorithm was used to establish an optimization design system to optimize the product prototype form un-der the target image. The coupling optimization of product prototype form design under the target image was realized, and the re-fined form of consumer emotion cognition was obtained. This method can optimize the product image prototype reasonably and ef-fectively, and realize the detailed design of product form. |
