摘要：
According to the demands of different layers, the solid models shape descriptor, dilation based multiresolutional skeleton (DBMS) graph was generated based on local dilation. Then based on DBMS graph, the matching of multi-subgraph in the same level was researched and multiresolutional similarity assessment of DBMS graphs was given to complete multiresolutional matching efficiently and accurately. Experiments show that the algorithm has good precision/recall and can give satisfied retrieval results for users of different design stages efficiently.
