3D CAD Model Retrieval Using 2D Representative Views

A novel 3D CAD model retrieval method using 2D representative views is proposed for the reuse of CAD models. Initially, a set of 2D projected views is generated from multiple viewpoints which are evenly distributed on the viewing sphere of a CAD model. Then, the Apriori algorithm is employed to select the representative views from the set. The similarity between 3D models is determined by the likeness of their corresponding 2D representative views. The experimental results show the effectiveness of the proposed method.
