中文摘要：

随着视频监控系统的普及和推广,资源共享已经成为异构视频监控系统集成中亟待解决的关键技术问题之一。而传统视频系统集成模型和技术在应用中存在着扩展性和稳定性方面的不足,针对此问题提出了基于节点自治的系统集成模型及技术。通过定义模型中不同角色节点的服务,既屏蔽了系统间的异构性又保持原系统的独立性;通过对视频服务节点设计的自描述服务增加了系统的可扩展性。典型工程应用结果表明了该系统集成模型及技术的有效性和优越性。

英文摘要：

With an ever-increasing usage of video surveillance systems,the demands for resource sharing become a topical subject.However,it is always troublesome to extend and stabilize such systems.Aiming at above shortcomings,a model based on the node autonomy was proposed.Defining and using service nodes,not only the heterogeneity of the systems was solved,and the independence of each system was enhanced as well.Also,in terms of self-describing service of video nodes,the extensibility of the model was obviously increased.Confirmed by numerical applications as reported,the results indicate the feasibility and advantages of the proposed method.
