摘要 首先介绍了一个完整的3维模型检索系统的研究内容,然后对其中的关键技术3维模型特征提取方法中的统计特征提取方法、骨架提取方法、基于几何学的提取方法进行了分析比较。最后提出了3维模型检索技术今后需要研究的一些问题。 Firstly, the main content of an entire three dimensional model retrieval system is discussed. Then, it analyzes 3D model feature extraction methods respectively based on statistic characteristics, skeleton, geometry of object image. Finally, some problems need to be resolved in 3D model retrieval technology are summarized.
