Research On Technology Of Content-Based 3D Model Retrieval

Recent development of computer graphics and 3D modeling has led to a rapid increase of 3D models. At the meantime, 3D models are used in more and more fields. People often want to use a tool to help them find desirable 3D models from internet or model databases efficiently and accurately. So researching and developing of the 3D model retrieval system with good performance has become a hot research topic.The research work in this dissertation is mainly about some technology in content-based 3D model retrieval, such as feature extraction, relevance feedback and so on.Firstly, we expound the main content of 3D model retrieval and its great importance, summarize and analyze some relevant technology and enumerate some typical 3D model retrieval system.Secondly, we do some research on voxelization-based feature...
