碩士 === 國立中央大學 === 資訊工程學系 === 104 === 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.
