Part-based comparison and retrieval of 3D models

本研究的目的是开发一种基于零件的三维模型检索算法。基于零件的3D模型检索算法返回其零件(S)类似于查询的整个3D模型。为此，我们发展了必要的构件技术，即(1)局部形状特征，(2)局部特征比较方法，(3)局部特征集比较方法，(4)基于部件的查询合成和表示方法。我们还开发了一个基准数据库，用于评估基于零件的3D模型检索算法的性能。

Objective of this research is to develop an algorithm for part-based 3D model retrieval. A part-based 3D model retrieval algorithm returns a whole 3D model whose part(s) resembles to a query. Toward the goal, we have developed necessary component technologies, that are, (1) local shape features, (2) methods to compare local features, (3) methods to compare set of local features, and (4) method to compose and present a part-based query. We also developed a benchmark database for evaluating performance of part-based 3D model retrieval algorithms.
