工程图检索原型系统的研究与实现

Research & implementation of content-based engineering drawing retrieval

文中实现了一个工程图形检索原型系统DRS(Drawing Retrieval System),并且给出了相应的实验结果,包括整体相似性检索结果、局部相似性检索结果及基于本体的工程图形语义相似性检索结果,初步验证了文中的研究成果。实验结果表明,该系统具有良好的稳定性和有效性,能够有效促进企业产品设计和制造相关信息的重用。

A prototype system DRS （Drawing Retrieval System） is developed in this paper. Meanwhile, some tests including global retrieval, local retrieval, and semantic similarity retrieval based on ontology, and the applications of the retrieval results are conducted to validate research achievements. The experiment results show that the prototype system has favourable stability and effectiveness, and it can effectively facilitate the reuse of product design and machining information.
