嵌入式视频监控系统充分利用 ARM 技术和网络的科技成果，实现远程监控、体积小巧、功能稳定的监控产品。开发一套基于嵌入式 ARM 的远程视频监控系统，系统采用 USB 摄像头作为前端图像采集传感器，图像数据通过 USB总线传出给 CPU 做处理，在此基础上实现图像的背景减除算法的应用通过编写 USB 摄像头底层驱动来实现图像的传输，通过 V4L2接口获取视频图像，将获取的图像经过滤波灰度转换后加以背景减除，实现运动目标的入侵检测了。通过实验测试，检测系统在其运行的24小时内对运动物体的检测效果良好。%Embedded screen monitoring system makes full use scientific and technological achievements of the ARM technology and networks ,remote monitoring ,compact ,stable monitoring product .a set of remote screen monitoring system is developed based on embedded ARM ,the system uses the USB camera as the front image acquisition sensor ,the image data to the CPU via the USB bus came to do processing ,image background subtraction algorithm based on this application by writing USB camera driver to achieve the underlying image transmission ,access to screen images via V4L2 interface image acquired after filtering through gradation conversion to background subtraction ,intrusion detection of a moving target . Through experimental test ,the detection system within 24 hours of its operation good moving object detection results .
