摘要:

为推动鞋楦设计的快速化、个性化、多样化发展,提出并实现了一种基于旋转变换的鞋楦变翘曲面重构CAD技术。交互选定两变换截面,通过旋转变换将鞋楦前翘高、后翘高等参数值变换到个性化设计需求值;对变换后的鞋楦进行均化处理,实现两变换截面处的鞋楦曲面平滑过渡;对楦底腰窝部中轴线进行微调并将微调量映射到鞋楦模型上来设计与变换后鞋楦相匹配的鞋楦腰窝段。利用提出的曲面重构过程在MATLAB软件平台上设计了参数化和可视化交互式两种方法进行鞋楦变翘设计的CAD模块,其界面具有操作简单方便、易于实时编辑的特点。通过对算法实现结果的高斯曲率和体积进行分析,rhf 验证了重构后鞋楦模型能很好地保持原鞋楦的合脚性及曲面光顺性特征。

Abstract:

A surface reconstruction method of shoe last deformation was proposed and implemented to promote the rapidness, personalization and diversity of shoe last design. The shoe last toe spring, heel height and wedge angle were transformed into the required values of personalization design by rotating transformation based on the two transform sections of interaction selected processing; the homogenization processing was conducted to the transformed shoe last to realize the smooth transition of the shoe last surface in the two transformation sections; the waist region of the shoe last matched with the transformed shoe last was designed by the fine adjustment of the axle wire of the shoe last bottom waist region and mapping to the shoe last model. The proposed surface reconstruction process can realize the parameterized and visual interactive methods to carry on the CAD module of last design on MATLAB software platform, and the interface is simple and convenient to operation and easy to real-time editing. The reconstructed shoe last model was proved well keeping the original shoe last fit and surface fairing through the analyses of volume and Gauss curvature of the surface of the original and reconstructed shoe last.

Key words: shoe last, toe spring and heel height, surface reconstruction, rotating transformation, parametrized design, interactive design
