Heterogeneous Video Surveillance System Integrated Key Technologies To Achieve

With the rapid development of advanced computer technologies and multimedia technologies, Video Monitoring System (VMS), which is nowadays treated as one of the most intuitionistic ways to public security and resource allocation has been achieved popularization and spread. Meanwhile, a large number of organizations and enterprises are lack of the overall planning during the implementation of video monitoring system. In addition, there are numerous manufacturers and brands are complicated and standards of technological integration are also deficiency. All these reasons bring to the coexistence of many isomerous video monitoring systems. Video resources sharing have become one of the crucial technological issues contribute to the integration of isomerous video monitoring systems as well as the integration between video monitoring systems and video conference systems. Aiming at this problem, this thesis has analyzed the weakness of traditional video conference system integration models and technology applications from the aspect of extensibility and stability, and then comes up with the solutions of isomerous video monitoring system integration on the basis of virtual video collection device middleware along with relative researches of the critical technologies.Having done adequate research on interfaces of WDM driver models and DirectShow framework, the thesis has proposed an integration solution of isomerous video monitoring systems on the basis of video forwarding middleware technologies with more extensibility and stability. Then, the thesis has carried out relative researches on the implementation of virtual video middleware. The middleware put forward by this thesis included virtual video collection devices, function of video data processing and assistant controlling of monitoring. Virtual video collection devices are mainly responsible for the two-way interfaces, one of which transmitting data into them and the other one to offer standard interfaces for video data transmitting to video conference systems. Function of video data processing can make the obtaining, processing and transmitting of data produced by monitoring systems with different structure realized. Assistant controlling of monitoring may contribute to the remote controlling of rotation between video sources, PTZ controlling and shooting of videos. The application of the thesis achievement in typical projects indicates that the system integration solutions and technologies do have effectiveness and advantages.
