摘要
以德州仪器(TI)推出的多媒体图像处理器TMS320DM643作为核心单元,设计了一个单通道的视频采集分析存储系统。基于此系统提出了将PERCLOS测量方法在DSP上实现的方法,并给出了程序流程。设计此系统的目的是为了减少因疲劳驾驶而产生的交通事故的发生率。实验得出,文中提出的方法克服了传统的驾驶员疲劳检测系统需要在驾驶员身上安装测量装置或者需要驾驶员周期性重复某项动作的弊端。该系统疲劳检测准确率较高,可用于火车、长途客货车驾驶员防瞌睡,降低交通事故发生率。
In this paper, a single- channel video collection, analysis and memory system is deigned, multimedia image prccessor TMS320SM643 as its core. The method that the PERCLOS measurement realized on DSP is introduced ,and the procedure flow is given. The destination is to reduce the incidence. The drawback of traditional driver＇s fatigue detection system which need to install measuring device and repeat periodical movement on driver is overcome . Experimantal results show that the fatigue detection rate in this system is high, and it can prevent driver of train and long - distance vehicle from dozing in order to reduce the incidence of traffic accidents.
