Design And Implementation Of Video Investigation Auxiliary System For Public Security Organs Based On SSH

For a long time,a large number of video images provided by video surveillance system have been an important basis for the investigation of cases in public security organs,and video detection technology has also become an important means for public security organs to carry out investigation work.However,with the explosive growth of video data,public security organs need to get useful information through video fast processing,so the dependence on video monitoring system is becoming more and more obvious,but the system is short of video analysis and fast retrieval function,and can not meet the practical application needs.In this context,this topic integrates the technical advantages of the mainstream video monitoring system,analyzes their technical short board,quotes the system framework and development technology of the front,in order to build a set of video detection auxiliary system supporting distributed processing and practical application,and determines the following two design objectives:one,can It provides technical support for the video research of public security cases;secondly,it realizes the distributed storage management of massive video images based on the Hadoop framework and the Oracle relational database.In this study,first,the functional requirements and performance requirements of the public security organs for video detection auxiliary system are clarified,and a requirement scheme is formulated.The basic design principles and design objectives are established to provide guidance for the follow-up system design.Then,according to the results of the requirements analysis,the Hadoop framework and Lucene are designed.The overall architecture of the system,the selection of SSH architecture and the design of the system system based on MVC thought,divided the main functional modules,and then based on the data and data types and other indicators,a mixed data storage scheme based on the Hadoop framework and the Oracle database was formulated.At the same time,the database subsystem has completed the realization of the core function of the system.Finally,this paper designs a variety of use cases to carry out a comprehensive test of the developed video detection auxiliary system.The test results prove that the system basically meets the functional requirements of the design scheme,and shows excellent performance,especially in the video distributed system.It has advantages in processing and massive data retrieval,and can be deployed,installed and put into use.
