为重建馆藏青铜器香薰三维模型和研究其制造工艺，利用高精度计算机断层扫描系统进行数字成像（DR）和锥束扫描（CT）两种方式扫描香熏，获得其灰度图像，经过图形图像处理，获取表面轮廓三维数据。表面定义和提取后，将数据输入逆向工程软件系统，重建香熏的三维CAD模型。结果表明，获得的点云数据密集均匀，未见扫描盲区；发现香熏存在焊孔和变形；逆向三维重建的香熏CAD模型具有良好的几何相似性。研究提示，高精度计算机断层扫描方法空间分辨率高，精确度高，可以作为一种获取青铜器三维数据的可靠方法。

A high resolution computer tomography system employing Digital Radiography （DR） and Cone - beam Tomography （CT） was used to construct three - dimensional （3D） models of a bronze incense burner in the museum collection, with the aim of understanding its technique of manufacture. Surface 3 D information was collect- ed after obtaining greyscale images and graphics and image processing. This data was then processed in a reverse engineering software system and used to construct a 3D computer- aided design （CAD） model. Analysis of the model shows that the data points are scattered evenly and that there were no blind areas. It is also found that the burner has welding holes and sites of deformation. The constructed 3D CAD model of the burner has very good geometric similarity to the original object. This study shows that high resolution computed tomography has high spacial resolution and precision, and is a reliable method for obtaining 3D structural data on bronzes.
