摘要
我国历史悠久,文化遗产众多。时光飞逝,文物因受到自然或者人为等因素的影响,损毁严重,因此很有必要对文物采取保护措施,即对文物进行三维数字化处理。针对文物三维建模问题,查阅了大量资料,通过文物三维信息采集技术的不同对文物三维建模方法进行了阐述。文中主要论述了基于三维激光扫描技术、二维影像技术包括无人机摄影测量与近景摄影测量、3D打印技术、电子计算机断层扫描(ComputedTomography,CT)技术进行文物三维重建的方法,对比分析各方法的优缺点,为文物三维建模的研究和实践提供参考。
China has a long history and many cultural heritages.Time flies,cultural relics are seriously damaged by natural or man-made factors,so it is necessary to take conservation measures for cultural relics,i.e.,to digitize them in three dimensions.For the problem of three-dimensional modeling of cultural relics,a large amount of information has been reviewed,and the threedimensional modeling method of cultural relics has been elaborated through the different techniques of three-dimensional information acquisition of cultural relics.The paper mainly discusses the methods of 3D reconstruction of cultural relics based on 3D laser scanning technology,2D imaging technology including UAV photogrammetry and close-up photogrammetry,3D printing technology,and electronic computer tomography Computed Tomography(CT)technology,and compares and analyzes the advantages and disadvantages of each method to provide reference for the research and practice of 3D modeling of cultural relics.
