摘要
提出一套基于嵌入式的数字视频监控系统,在高性能双核芯片OMAP5910(ARM核和DSP核)的基础上,以Internet为支撑,以V4L为基础,对USB接口的摄像头采集的数据进行处理,在OMAP5910和Linux2.6.14上实现了USB蓝牙驱动,并介绍了Linux2.6下蓝牙通信的实现过程,即实现视频的采集并送至监控中心,同时将视频图像做运动检测,如果检测到有人入侵,就通过蓝牙传送至家庭内PC,并同时启动GPRS短信功能报警系统,实现远程监控。
A digital video surveillance system based on embedded Linux is presented in this paper. The basis of this system is the high-performance OMAP5910 dual-core chips （ARM core and DSP core） and V4L . Supported by the Internet, the system processed the data acquired by the camera on the USB interface .It also achieved Bluetooth USB drive in the OMAP5910 and Linux2.6.14. This paper introduced the process of bluetooth communications in the Linux2.6.14. That is to say, to realize the collection of the video and sent it to the monitor center, at the same time have the video images to do motion detection. As long as the system Detected the invasion ,it would transmit this information to the home PC via Bluetooth . In the meanwhile GPRS messaging alarm system be lanched for the remote monitoring.
