摘　　要： 随着数字图像算法和网络技术的发展,智能化和网络化已成为视觉监控的发展方向。针对网络智能视觉监控的需求,设计了基于BF533的嵌入式监控系统。采用了μC/OS-Ⅱ实时操作系统,使用差分算法和边缘跟踪算法作为核心算法。提供了网络接口并移植了TCP/IP协议,可以通过局域网向PC主机实时传送BMP图片和运动目标的位置等信息,并能提供Internet用户的实时图片浏览服务。系统能良好地跟踪运动目标并传送图片。 Along with the development of digital image arithmetic and Internet technology, intelligentization and networking become the developing goals of vision surveillance. Aiming at the demands of Internet intelligent vision surveillance, the embedded surveillance system based on BF533 is designed. In the system, btC/OS-]/ real-time operating system was adopted and the differential algorithm and edge-tracking algorithm are used as the kernel arithmetic. It provided network interface and transplanted TCP/IP protocol, so the BMP pictures and information of mov- ing targets were transferred to host PC via local area network in real-time basis. In addition, it could offer browsing service for real-time pictures to Internet users. The system is able to track moving targets very well and transmit pictures effectively.
