製鞋業為台灣重要的傳統產業,雖然近幾十年以來不斷有自動化的技術導入到鞋子的生產過程,然而一雙成品鞋仍需經過兩百多個人的手,才能完成。甚至在最重要的鞋面部的設計,需靠有經驗的技師才能完成鞋子的設計。在本論文中,我們實現一套從3D鞋楦模型轉換至2D鞋面布樣轉換系統,提升製鞋技術的自動化。本論文所提出的自動化設備包含:三維掃描平台及四軸裁切機,所提出的系統流程為使用三維掃描平台擷取鞋楦不同角度的3D表面點雲資料,在將多個表面點雲進行對位融合出一個完整三維點雲鞋楦模型。再透過人工選點選取鞋楦模型上的鞋面布分割參考點,並將鞋面布切割,攤平成2D鞋面布圖樣,為了能獲得全尺寸的鞋面布圖樣,針對每一部分依標準尺碼的三維資訊與二維資訊進行分段級放得到全尺寸的鞋楦模型及鞋面布樣板,所提出的系統也整合入一排版演算法,針對鞋面布進行固定面積排版,再由切割機控制程式依排版結果規畫路徑,根據鞋面輪廓進行移動規劃,完成切割。
Shoe making is an important traditional industry in Taiwan. Although automation technology has been introduced into the shoe production process in recent decades, a pair of finished shoes still needs more than 200 hands to complete. Even in the most important shoe face design, it needs experienced technicians to complete the design of shoes. In this paper, we implement a set of conversion system from 3D shoe last model to 2D shoe upper cloth sample, which improves the automation of shoe making technology. The automation equipment proposed in this paper includes three-dimensional scanning platform and four axis cutting machine. The proposed system process is to use the three-dimensional scanning platform to capture the 3D surface point cloud data of shoe last from different angles, and then integrate multiple surface point clouds to form a complete three-dimensional point cloud shoe last model. In order to obtain the full-size vamp pattern, the full-size shoe last model and upper cloth template are obtained by segmenting each part according to the 3D and 2D information of standard size. The proposed system is also integrated into a layout calculation According to the layout results, the cutting machine control program plans the path according to the typesetting results, and carries out the movement planning according to the upper contour to complete the cutting.
