摘要
本文介绍了一种基于红外光源得到的明暗瞳孔图像做差的人眼检测及跟踪方法,应用于疲劳驾驶检测系统。利用DSP芯片来控制红外光源,获取实时图像。采用差分图像进行人眼瞳孔图像的定位检测,利用卡尔曼滤波法跟踪人眼,以适时检测眼睛的开闭状态。该方法具有准确、快速、全天候且对驾驶员无干扰等优点。
A method applied in eye pupil detection and tracking is introduced based on the difference of light pupil images and dark pupil images by infrared light.The digital signal processor(DSP) is used for real-time image acquisition and controlling the IR light source.This method adopts the differential image to locate and detect pupil.Kalman filter is implemented to track the eyes in order to detect the state of the eyes.The system is accurate,fast,all-weather and noninvasive.
