摘　　要：基于内容的月球影像检索面向月球探测计划获取的大量遥感数据,根据影像视觉内容,提供一种方便而高效的检索方式。为提高其检索效率,在对基于内容的月球影像检索过程进行分析的基础上,运用Petri网完成过程建模与并行化分析。提出一种基于内容的月球影像检索并行框架,并据此部署实验系统,将嫦娥月球影像等实际数据集投入其中进行检索实验。结果表明,基于内容的月球影像检索并行框架能够有效提升查询检索效率。Content-based lunar image retrieval provides a convenient and efficient way for accessing relevant lunar exploration images by their visual contents. To increase the efficiency, the process of content - based lunar image retrieval was analyzed and modeled using Petri nets, and a parallel mechanism was designed based on the model. A parallel architecture was then proposed for the content based retrieval of lunar exploration images. According to the architecture, an experimental system was implemented. Experiments upon real datasets including Chang＇ e lunar exploration images confirm that the proposed parallel architecture can effectively improve the constructive and retrieval efficiency.
