解构.重构思维下的仿生产品参数化生成研究

目的 在解构.重构思维下探索产品形态创新方法，发掘产品形态仿生设计的方案多样性。方法 阐述了解构.重构思维的理论应用、参数化设计方法应用流程。以自然花朵为实例研究，在搜集的牛津102与17花朵数据集中筛选出158张样本图片;首先通过Grabcut、Sobel、Canny等相关轮廓算法得出花朵平面轮廓，将特征轮廓进行解构分类后参数化表征;其次利用Rhino-Grasshopper软件重构花朵抽象三维模型，利用产品结构约束重构仿生产品;最后以灯具为例，调整参数后得到有花朵形态特征的产品形态重构群，得到基础仿生灯具模型，结构约束后得到仿生灯具三维模型。结论 该方法进一步探索了计算机辅助产品设计研究，实例表明自然花朵通过此方法可以生成大量具有创新性的形态初步模型，提高设计效率。

Parametric Generation of Biomimetic Products under Deconstruction and Reconstruction Thinking

three-dimensional model of the flower, and the bionic product was reconstructed by the structural constraint. With the lamp as an example, after adjustment of parameters, the product form reconstruction group with flower form characteristics was obtained, and the basic bionic lamp model was gotten. After the structural constraint, the 3D model of bionic lamp was obtained. This method further explores the research of computer-aided product design, and the example shows that natural flowers can generate a large number of innovative preliminary models for form through this method, which improves design efficiency.
