ABSTRACT = {Real-time and effective monitoring of a driver’s physiological parameters and psychological states can provide early warnings and help avoid traffic accidents. In this paper, we propose a non-contact real-time monitoring algorithm for physiological parameters of drivers under ambient light conditions. First, video sequences of the driver’s head are obtained by an ordinary USB camera and the AdaBoost algorithm is used to locate the driver’s facial region. Second, a face expression recognition algorithm based on an improved convolutional neural network (CNN) is proposed to recognize the driver’s facial expression. The forehead region is divided into three RGB channels as the region of interest (ROI), and the ICA algorithm is used to separate the ROI into three independent components. After that, the most significant component is selected for calculation of the heart rate and respiratory rate of the driver. Comparing the experimental results with the indications of finger clip devices, the proposed algorithm can monitor a driver’s physiological parameters in real time in a non-contact way that will not interfere with normal driving. The results of facial expression recognition can help verify the monitoring results of physiological parameters, and therefore, more accurately evaluate drivers’ physical condition.},
