摘　　要：针对公路客运车辆运行中存在的事故多发问题,设计了一种能够实时警示和记录驾驶员违章驾驶行为的客运车辆运行状态图像监控系统。该系统采用SEED-VPM642高速视频图像处理DSP作为图像处理平台,利用CCD图像传感器进行前方道路图像的采集,MC9S12DG128单片机完成车辆行驶状态参数的采集处理及声光预警。实验结果表明,该系统工作可靠性高、价格成本低,具有广泛的应用前景。For the problems of traffic safety of the highway passenger vehicle, a passenger vehicle driving state image monitoring system is designed, which can warn real-time and record drivers＇ illegal driving behaviors. Adopting SEED-VPM642 high-speed video image processing DSP as the platform, this system used CCD image sensor for image acquisition in front of the road and MC9S12DG128 MCU to complete the acquisition and processing parameters of vehicle operation and sound and light warning. The experimental results show that high reliability work and low cost price of this system has broad application prospects.
