3D模型的使用越来越受欢迎，因为它们对计算机图形应用程序很重要。近年来，为了系统地处理三维模型数据库，人们对三维模型相似检索技术进行了深入的研究。该技术从3D模型中提取形状描述符，并使用这些描述符作为比较形状相似性的索引。已经提出了各种形状描述符来改进形状相似性搜索结果。大多数相似性搜索技术侧重于对数据库中每个单独的3D模型进行比较。然而，我们的相似性搜索技术不仅可以比较每个单独的3D模型，还可以比较部分形状的相似性。部分形状匹配技术通过(1)找到3D模型的相似部分，(2)找到包含相似部分的3D模型，(3)自动统计相似部分的数目来扩展用户的查询请求。我们实现了一个实验性的三维模型数据库部分形状匹配搜索系统，初步实验表明，该系统成功地检索到了相似的三维模型零件。
The use of 3D models is gaining popularity since they are important for computer graphics applications. Recently, similarity retrieval techniques for 3D models have been investigated intensively for handling databases of 3D models systematically. The techniques extract shape descriptors from 3D models and use these descriptors for indices for comparing shape similarities. Various shape descriptors have been proposed for improving shape similarity search results. Most similarity search techniques focus on comparisons of each individual 3D model from databases. However, our similarity search technique can compare not only each individual 3D model, but also partial shape similarities. The partial shape matching technique extends the user’s query request by (1) finding similar parts of 3D models, (2) finding 3D models which contain similar parts, and (3) counting the number of similar portions automatically. We have implemented an experimental partial shape-matching search system for 3D model databases, and preliminary experiments show that the system successfully retrieves similar 3D model parts efficiently.
