Computeraided optical digitization technique appears to be a powerful tool for the 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.
