光學式鞋楦3D模型構建與特徵資料量測

Abstract

鞋楦量測是鞋楦經設計與製造之後，最重要的確認工作項目．傳統的 鞋楦量測工作，都是以人工方式量測完成，其過程完全是憑藉個人的經驗 與熟練程度，來決定鞋楦量測的品質．因此本文提出利用高科技設備來對 鞋楦進行自動化量測檢驗的工作．本研究利用雷射線式三次元掃瞄機，掃 瞄取得鞋楦模型資料，並發展多個演算法，由掃瞄所得之資料中，自動擷 取出鞋楦重要組合部份的形態資料，所擷取出的鞋楦特徵資料又以數字化 ，圖線化的方式彙總，利用電腦圖學的技術顯現於電腦螢幕上，方便資料 的比對與參考．本文所發展的鞋楦3D模型構建與特徵資料量測系統，已在 PC/486系統以Ｃ語言模擬實作完成，實驗結果相當令人滿意． The shoe last measurement is an important work to assure the quality of design and manufacturing. Traditionally , the measurement is done byexperienced technician . In this paper , a new measurement method isproposed using hight technological equipment . A high speed and highprecision 3D scanner is used to obtain the shoe last data . The associatedfeature values of the shoe last can then be derived by a set of algorithms . The extracted shoe last feature values and shoe last model are shown on themonitor by using computer graphics techniques . This will be convenient forcomparison and reference . The proposed 3D shoe last construction and feature measurement system has been implement on PC/486 in C language . Experimental results show that the proposed system is very feasible and effective .
