摘　　要：针对汽车驾驶员疲劳驾驶检测的要求,设计了一种基于图像处理DSP芯片DM6437的疲劳驾驶视觉检测系统。通过DSP的GPIO口用软件控制摄像头轴上和轴外的两种不同波长的近红外光源(850nm/950nn)交替采集驾驶员图像,根据亮瞳效应两帧图像差分后粗定位人眼,用模板检测提取人眼的边界,根据PERCLOS值方法判断驾驶员是否疲劳。根据人眼的不同状态分别处理,用蜂鸣器作为报警系统提醒驾驶员。实验表明,该系统简单实用,而且能够全天候准确快速地判断驾驶员是否疲劳。To accomplish the request of driver fatigue detection,a driver fatigue detection system based on DM6437 is designed.The inner axis and outer axis IR light are controlled by GPIO peripheral.The two driver＇s images are acquired using inner axis and outer axis IR light in turn.According to bright eye effect,the eyes are detected from the difference of the two images.The fatigue degree of driver is determined by PERCLOS.The different conditions of eyes are processed respectively.Finally,the alarm is sounded when in fatigue condition.Experimental results show that the useful system can detect the driver＇s condition accurately and quickly at any time.Also,it will not disturb the driver＇s normal driving.
