3-DIMENSION COMPONENTS SHAPE RETRIEVAL AND INDEXING

Abstract

Abstract: Efficient case retrieval is a key factor in case-base design. A case retrieval algorithm is proposed which uses the volume ratio of 3-dimension component and its bounding box to extract feature values. It can deal with irregular shape components. The first step is pose normalization based on the analysis result of irregular component shape. Next to partition component for compute volume ratio and build similarity evaluation model. The retrieval result provides correlation feedback. At last an indexing scheme is proposed based on similarity evaluation model.

Key words: 3D component, Case retrieval, Integral, Volume ratio
