英文摘要	三维扫描技术是集光电为一体的数字化成像技术，能获得立体器物的三维数字化模型。本文通过相位辅助的三维扫描技术对不同时期、不同类型的陶、瓷器构建三维数字化模型，进行几何尺寸的非接触测量、虚拟修复、考古学的类型学研究等。同时结合多光谱成像、LRS、OCT、XRF、体视显微镜的分析结果，构建文物的多源信息数字化模型，通过科学的手段对文物的研究和保护提供技术支持，为文物的数字化保护和数字博物馆的建立提供科学依据。 本文的主要内容包括以下方面： （1）基于国内外三维扫描技术在文物遗产保护方面的应用进行现状分析，探讨三维扫描技术在文物保护与研究领域的应用优势。并阐述了三维扫描技术的原理和技术。 （2）利用相位辅助三维扫描设备获取新石器时代晚期的仰韶文化彩陶碗的三维数字化模型，并进行几何尺寸的非接触测量；利用数字雕刻和绘画软件将彩陶碗三维数字化重建模型进行UV展开和虚拟修复；通过多光谱成像技术获取样品的反射率谱线，根据反射率谱线的变化趋势进行样品表面化学特征相似区域的区分。结合XRF和LRS确定所分析彩陶样品的主要化学成分特征和颜料物相组成。 （3）使用相位辅助的三维扫描仪对扬州汉代时期的原始瓷器物进行三维扫描成像和几何尺寸的非接触测量。利用几何尺寸信息的数值关系进行原始瓷的类型学研究，分析西汉不同时期原始瓷形态演变；并利用XRF分析原始瓷胎釉的化学元素组成，利用OCT对原始瓷的胎釉进行断面结构的分析，确定胎釉结合面、釉层结构在二维断面的形态特征、透光性、釉层的缺陷原因等。 （4）应用多光谱成像、超景深体视显微分析、OCT、XRF和LRS技术，对景德镇高仿鸡缸杯、明清彩瓷片的光谱特性、釉彩图案细节、断面结构、化学组成和物相结构进行面、点相结合的综合分析。并通过分析结果对比仿制鸡缸杯与明清彩瓷片之间的差异。; Three-dimensional scanning technology is a digital imaging technology, which can scan three-dimensional object and obtain its digital model. Use phase assisted 3D scanning technique to construct 3D digital model for different periods and types of pottery and porcelain and achieve non-contact measurements of geometric dimensions, virtual restoration, typological study of archaeology. Then, with the results of multispectral imaging, LRS, OCT, XRF, stero-microscopy, obtain the multi-source information digitization model of Cultural relics. It provides technical support for the research and protection of cultural relics through scientific means and provides scientific basis for the digital research of cultural relics and the establishment of digital museum. The main contents of this paper include the followings: (1) Analyse the current situation of the application of 3D scanning technology in heritage protection at home and abroad and discuss the application advantage of 3D scanning technology in the field of cultural relics conservation and research. Expound the principle and technology of 3D scanning technology. (2) Obtain the 3D digital model of the colored pottery bowl of Yangshao culture in the late Neolithic period by using phase assisted 3D scanning equipment and the non-contact measurement of the geometric dimension is carried out; Obtain the UV expansion and carry out virtual restoration of 3D reconstruction model of painted pottery bowl by digital engraving and painting software. Then, the reflectance spectra of the samples are obtained by multispectral imaging. And discriminate the similar areas of surface chemistry characteristics of samples according to the variation trend of the reflectance spectrum; Based on the results of XRF and LRS, the main chemical composition and pigment phase composition of the samples are determined; (3) 3D models of proto-porcelain in the Han Dynasty of Yangzhou are obtained by using phase assisted 3D scanners. And use digital models of proto-porcelain to do non-contact measurements of geometric dimension. The typology of proto-porcelain are studied by using special numerical comparison of geometric dimension information. Finally, analyse the evolution of proto-porcelain morphology in different periods of the Western Han Dynasty; Analyse the chemical composition of the body and glaze of proto-porcelain by XRF; Section structure of proto-porcelain is analyzed by OCT and determine bonding surface of the body and glaze, glaze structure, transmittance, causes of defects in glaze layer and so on. (4) With the application of multi-spectral imaging, stero-microscopy, OCT, XRF and LRS, the spectral characteristics, glaze pattern details, cross section structure, chemical composition and phase structure of Jingdezhen high imitation chicken cup，color porcelains in Ming and Qing Dynasty are comprehensive analysed by the combination of face and point. Then, the difference of imitation chicken cup and color porcelains in Ming and Qing Dynasty are compared by the analytic result.
