摘要
针对当前室内安全系统智能化程度不高、硬件成本高等问题,研究基于ARM11,以S3C6410为微处理器,Linux为操作系统,设计一套智能室内安全视频监控系统。首先,通过分析系统需求,对系统整体框架进行设计,将系统分为视频采集端、服务器端、视频监控端三个部分。然后,根据系统整体框架,从嵌入式硬件平台、视频采集设备、二维舵机、网络设备对系统硬件进行配置;采用V4L2结构设计了系统采集端软件,采用网页在线控制方式实现了二维舵机驱动及控制,采用三帧差分法实现了移动目标识别和移动目标的监控,并基于时间的定位索引,增加了视频时间定位功能。最后,通过系统测试,验证了本系统的有效性。结果表明,本系统可稳定运行,可实现实时监控监测室内环境,满足实时监控需求,为室内环境的安全防范提供了保护措施。
Aiming at the problems of low intelligence and high hardware cost of the current indoor safety system,an intelligent indoor safety video monitoring system is designed based on ARM11,S3C6410 as microprocessor and Linux as operating system.Firstly,by analyzing the system requirements,the overall framework of the system is designed,and the system is divided into three parts:video acquisition end,server end and video monitoring end.Then,according to the overall framework of the system,the system hardware is configured from embedded hardware platform,video acquisition equipment,two-dimensional steering gear and network equipment;The system acquisition software is designed with v4l2 structure,the two-dimensional steering gear drive and control are realized by web page online control,the moving target monitoring of moving target recognition is realized by three frame difference method,and the video time positioning function is added based on the time positioning index.Finally,through the system test,the effectiveness of the system is verified.The results show that the system can run stably,realize real-time monitoring of indoor environment,meet the needs of real-time monitoring,and provide protection measures for the safety of indoor environment.
