城市图像监控与预警系统是集安全防范、计算机应用、网络通信、视频压缩传输、访问控制等高新技术为一体的庞大系统;城市图像监控和预警系统的建设提升了城市管理水平。但是,如何监控和分析这些大量的视频数据,从中及时发现有用的知识,提高信息利用率,及时预警,则是迫切需要解决的问题。采用数据挖掘技术分析视频数据,追踪潜在信息,并对某些区域进行重点监控,可以大大减少其工作量,及时报警,提高预警分析能力。
The city image monitoring and early warning system is a huge system integrating security, computer application, network communication, video compression and transmission, access control and other high and new technologies. The construction of urban image monitoring and early warning system enhances the urban management level. However, how to monitor and analyze such a large amount of video data, find out the useful knowledge from time to time, improve the utilization rate of information and give early warning are the urgent problems to be solved. The use of data mining technology to analyze video data, track potential information, and focus on monitoring certain areas can greatly reduce the workload, timely alarm, improve early warning analysis capabilities.
