摘要
针对云制造环境下各行业资源难以统一描述、资源云池内可用资源更新滞后、资源匹配计划执行力度弱等问题,提出一种显形表达资源动态变化的层次环境视频语义模型。该模型通过面向变化的三域(特征域-行为过程域-结果域)定义环境视频语义的层次结构和数据的层次表达,在各层次语义描述中将环境视频语义与视频内容语义有机结合,支持多地环境视频数据的关联表示,为后续云制造环境下资源匹配的动态实时、高效及可靠奠定了基础。
Aiming at the problems that the difficult unified description of resources, the lag of available resources in the resource cloud pool and the weak implementation of resource matching plan of various industries in the cloud manufacturing environment, a hierarchical environmental video semantic model for visually expressing resource dynamic changes was proposed. The model defined the hierarchical structure of environment video semantics and the hierarchical expression of data through the change-oriented three domains(characteristic domain-behavior process domain-result domain), and organically combined the environmental video semantics with video content semantics in each hierarchical semantic description. The association representation of multi-environmental video data laid the foundation for the dynamic, real-time, efficient and reliable resource matching in the subsequent cloud manufacturing environment.
