    Abstract: 針對同時具有銳利邊緣和平滑曲面的3D物體,傳統的結構光3D掃描的編碼方法通常不具有良好的適應性。本研究結合了空間鄰近與時序多工編碼,藉由時序相位與De Bruijn序列的整合,實現了一個高性能的3D掃描系統。此一系統具有較高的3D掃描精確度和執行效率。實驗結果顯示,對於複雜物體表面的3D掃描,我們的方法所得到的3D模型不僅輪廓精密度較高,而且當物體表面同時存在銳利與平滑曲面、陰影及反射所造成的表面雜訊,本系統均可順利重建三維輪廓,表現出良好的適應性。;The coding method adopted in a conventional structured light 3D scanner generally exhibits unfavorable adaptability when processing 3D objects with sharp edges and smooth curved surfaces. In this study, a high-performance 3D scanner system was developed by combining temporal multiplexing and spatial neighborhood coding methods and integrating timing phase with De Bruijn sequences. The proposed system can accurately and efficiently execute 3D scanning. The experimental results revealed that when scanning the surface of a complex object, the proposed system produced a 3D model with highly precise profiles. When scanning the surface of objects that features sharp edges and smooth curved surfaces and noise signals caused by shadows and reflections, the system proposed in this study can effectively rebuild the 3D profile of the object and thus demonstrates excellent adaptability.
