摘　　要：计算机辅助光学三维数字化技术作为一种有力的工具,可应用于文物三维原真信息的获取、存储和修复.本文提出一种获取可移动文物高准确度彩色三维数字成像法,包括基于光束平差的标定技术和相位辅助的主动三维成像技术.报道了可移动文物三维成像与建模的方法构建和实现过程,并利用该方法对典型薄壁结构的青铜器进行实验研究,验证了所提出真实感三维成像方法的有效性,建立了一种用于可移动文物三维成像的仪器原型.Computer-aided optical digitization techmque appears to ,~ a pu generation, storage, and retrieval of three-dimensional digital information of cultural heritage, and therefore leading to a new generation of technology for digital preservation. In this paper, an efficient approach was presented for generating photorealistic three-dimensional image and model of movable cultural heritage. A dedicated color optical digitizer was also presented based on a strategy of modified fringe projection profilometry. The approach provided an efficient way to digitize and reconstruct photorealistic three-dimensional images and digital models of movable cultural heritage. Experiment results using bronze wares with thin-wall shape structures and complicated topologies as well as color attributes were given to demonstrate the feasibility of proposed method for digital preservation.
