3D Models and Digital Library
As one kind of the important media information format in the digital library, 3D models are becoming more and more necessary in the information system of the digital library. 3D data acquisition technology as well as the retrieval technology about 3D models is all the key issues for making use of digital library resource. In this paper, common methods for the three-dimensional data acquisition are shown at first. Then, we introduce the present condition of the retrieval technology, in which we also analyze the critical part such as feature extraction, similarity matching, and related results feedback. In addition, the digital watermark technology for protecting the copyright of the authores is introduced simply. At last, the future trend of the digital library and the 3D models is prospected.
