Design And Implementation Of Law Enforcement Supervision Visual Management Platform

With the construction of high-definition digital video surveillance system, the mode of traditional video surveillance can not meet the requirements, monitoring system functionality is slowly developing from to find historical information in the past to real-time warning and monitoring, intelligent video surveillance technology is introduced. Intelligent, high-definition, digital, Internet and other technology used in the monitoring system, bring the explosive growth of data, how efficient transmission, storage and dig and use of these large-scale data is imminent.In this context, Hebei Provincial Public Security to regulate law enforcement during synchronous recording work, the province’s public security is establishing Law enforcement supervision visual management platform, which covers Law enforcement track tracking system and Law enforcement supervision audio and video management system, to achieve from data collection, storage, analysis, display full automation, the entire law enforcement process visualization supervision.Key issues for the Technology and Platform, the main work and innovations are as follows:1. Law enforcement track tracking system based on "high-definition digital recording systems interrogation" as the carrier, the whole process of handling cases involving audio, image data, the system uses adaptive target template track video segmentation algorithm, we completed the handling of automated management area video form a law enforcement track and improve work efficiency.2. Intelligent cloud storage subsystem using HDFS + video optimized file system can be more efficient implementation of continuous video stream data storing and reading, distributed discrete storage technologies, clustering support load balancing, N + M redundancy capabilities to provide high reliability and continuity of service storage system for video analysis of large data provided the conditions.3. Law enforcement supervision and audio and video management system focus the whole process of handling audio and video data management, statistical analysis work. Full text search subsystem according to certain policies, the integration of Solr, ActiveMQ, ZooKeeper three open-source products to meet the users of structured data in real time, fast, accurate query functional requirements, to provide intelligent decision support system for law enforcement investigators.
