基于3D草图的个性化鞋楦设计

目的 将基于3D草图的曲面重建方法应用于个性化鞋楦设计。方法 对个性化鞋楦设计方法进行研究，确定足楦设计标准，使用基于3D草图的逆向设计方法，在脚部模型上创建包含足型关键参数的鞋楦3D草图。根据3D草图选择合适的曲面创建工具生成鞋楦CAD模型。通过修改鞋楦3D草图，实现鞋楦模型的变形设计。结论 以Geomagic Design X为设计平台，根据足楦设计标准，实现了基于足部扫描模型的鞋楦3D草图提取和CAD模型创建。修改鞋楦3D草图中头势曲线，在草图约束驱动下得到新款式3D草图，创建了新鞋楦模型，实现了个性化鞋楦的创建和再设计。

Design of Personalized Shoe Last Based on 3D Sketch

The work aims to apply the surface reconstruction method based on 3D sketch in the personalized shoe last design. The personalized shoe last design method was studied, and the foot last design standard was determined. The reverse design method based on 3D sketch was used to create 3D sketch of shoe last containing key parameters of foot shape on foot model. According to the 3D sketch, the appropriate surface creation tool was selected to generate shoe last CAD model. By modifying the 3D sketch of shoe last, the deformation design of shoe last model was realized. Taking Geomagic Design X as the design platform and according to the foot last design standards, 3D sketch extraction and CAD model creation of shoe last based on foot scanning model are realized. By modifying the head curve of shoe last 3D sketch, a new style 3D sketch driven by sketch constraint is obtained, thus creating a new model of shoe last, and realizing the creation and redesign of personalized shoe last.
