开发了一种嵌入式数字图像监控系统,采用基于背景差的前景分割运算和基于帧间差的动态背景更新算法对监控场景进行前景分割,提取运动目标信息,完成异常判断后,通过网络将异常信息及关键图像序列传送到监控客户端。该文介绍了嵌入式设备的硬件电路、驱动软件和应用程序设计,并给出了网络客户端程序的实现方法。
An embedded digital image monitoring system is developed. The foreground segmentation algorithm based on background difference and the dynamic background update algorithm based on interframe difference are used to segment the foreground of the monitoring scene and extract the moving target information. After the abnormality is judged, the abnormality Information and key image sequences are transmitted to the monitoring client. This paper introduces the hardware circuit, driver software and application design of embedded device, and gives the realization method of network client program.
