摘要
基于嵌入式技术的无线视频监控以其灵活性、高集成性、便捷性等诸多优点将取代传统的有线视频监控。基于目前视频监控的实际需求,结合嵌入式技术、图像处理技术,以及图像传输技术,设计并实现了一种可靠性高、性能优良、成本低的嵌入式视频采集及编码系统。它是视频监控的前端,是无线视频监控系统的一个子系统。该系统选用S3C6410微处理器作为核心板的控制器,采用USB接口的摄像头进行采集,。根据系统的功能要求,开发了ZC301摄像头和MFC的设备驱动程序,并采用内存映射方式和双缓冲思想编写了基于V4L的视频采集程序。,利用MFC驱动中的API函数,。测试表明,设计的系统视频采集效率高、图像连续性好、运行稳定。
本课题结合嵌入式技术和视频通信技术,该系统综合运用了RFID技术、传感器技术、ZigBee无线通信、计算机网络等多种技术,实现了对视频的无线采集、环境感知、人员感知、以及对视频的存储、播放和监控等功能,达到了更实际更方便的对视频进行处理,真正实现了视频监控系统的智能化和交互化的控制功能。
