摘　　要：为了实时分析驾驶员的驾驶行为以及提高行驶过程的安全性,本文对车载行驶安全监控系统的必要性、特点、功能及其总体结构进行了分析和论证。针对图像采集、处理、分析与控制需求,基于数字图像处理技术,设计了车载行驶安全监控系统硬件构成,该系统中央处理单元采用TMS320DM642嵌入式DSP芯片;根据汽车行驶特点,进行了软件工作流程设计。实验证明该系统达到了预期的目的。Aiming at real - time tracking of driving behaviors and improving safety, the paper analyzes and discusses the necessity, characteristics, architecture and function of onboard image - based on driving safety monitoring system. Directed against image collection, processing and understanding, based on digital signals processing technique, the paper also puts forward hardware design of onboard image - based on driving safety monitoring system, in which TMS320DM642, a kind of embedded DSP chips is used as a central processing unit. Software flow is also designed according to the driving traits. Experimental results prove that the system works well.
