A Method for Content-Based 3D Model Retrieval by 2D Projection Views

An effective approach for 3D model retrieval is to represent models by a set of projection views . In this paper, we propose a flexible framework for view-based 3D model retrieval. The framework provides users the ability to configure three components: the number of views, the type of views, and the 2D shape descriptors used to distinguish views. Because the three components are closely related to the performance of a view-based 3D model retrieval system and usually application-dependent, it is necessary to make them configurable. To achieve this goal, the framework employs a new view polyhedron positioning algorithm and provides an adaptable interface to its 3D shape feature extraction module. We build a demo 3D model retrieval system based on the framework. Experiment shows that the performance of the demo system is satisfactory.
