APPARATUS AND METHOD FOR RETRIEVING MODEL CONSIDERING DIFFERENCES OF LEVEL-OF-DETAIL BETWEEN QUERY AND RETRIEVAL TARGET MODELS

摘要

The present invention relates to an apparatus and a method for retrieving a model. More particularly, the present invention relates to an apparatus and a method for retrieving a model considering an accuracy difference between a query model and a retrieval target model. According to an embodiment of the present invention, the apparatus for retrieving a model comprises: an input unit for receiving a query model; a model simplification unit for simplifying at least one original model which is a retrieval target, and generating a simplified model; a similarity analysis unit for comparing a shape of the query model with that of the simplified model, and analyzing similarity between the query model and the simplified model; and an output unit for determining a retrieval model from the simplified model based on the similarity, and outputting the retrieval model.
