基于交互式遗传算法的产品配色设计

Color Mapping Design from Image to 3D Product Model

研究从平面图像到产品三维模型的配色方案自动映射机制。利用色彩合并与主色提取等技术从平面图像中获取配色方案,并据此构建产品配色方案解空间。在考虑色彩数量、比重和随机创意等因素的前提下,把配色方案从平面图像映射到三维产品模型表面,并将方案群以视觉化形态展示,供设计师选择。通过交互式遗传算法寻找最优方案,程序从设计师选择的方案编码中分析计算出隐含的设计师意象信息,并用以构建适应度评价函数推进方案的优化。在产品外观色彩设计中对设计方法进行验证,实现配色方案的自动化提取、映射和优化设计。

Automatic mapping mechanism of color scheme from plane image to product 3D product model is researched. Color scheme is obtained from plane image by using color merging and main color extracting techniques, and based on this, product color scheme solution space is constructed. Under the premise of considering the factors such as color number, proportion, and random originality, the color scheme is mapped from the plane image to the surface of 3D product model, and the color schemes are demonstrated in visual way for the designer to choose. Interactive genetic algorithm is used to seek for the optimal scheme. From the scheme codes chosen by the designer, the program analyzes and calculates the implicit information about designer＇s imagery, and uses it to construct the fitness evaluation function so as to push forward the optimization of scheme. Verification of the design method is carried out in the design of exterior colors of product, in which the automatic extraction of color scheme, mapping and design optimization are realized.
