In this paper, a vehicle location and video surveillance system is given to help passenger service center supervise long-distance vehicles. Based on ARM Linux OS and ARM processor, the system collects video data through the USB camera and obtains location information from the GPS receiver. Then the collected data are compressed and coded through H. 264 to form a standard format suitable for network transmission. Finally, the data are sent to the monitoring service center through 3G wireless transmission module based on 3G technology. And thus the staff in the monitoring service center can see clear and fluent video images and know where the car is.%为了加强客运服务中心对长途车辆在客运过程的监管,提出了基于ARM Linux的3G无线车载视频监控系统.该系统基于ARM Linux嵌入式系统与ARM处理器,通过USB摄像头采集车内视频数据,由GPS定位模块获取车辆的位置数据,然后将采集的数据经过H.264压缩成适合网络传输的形式.最终通过3G无线发射模块经过具有宽带传输能力的3G移动通信网络传输给监控服务中心,监控服务中心可以看到车内清晰流畅的视频画面以及车辆所在位置.
