Driver physiological monitoring in vehicle is of great importance to provide a comfortable driving environment and prevent road accidents. In recent years, the development of non-contact techniques for such monitoring has been drawing research interests. In this paper, we present a non-contact video-based driver physiological monitoring framework to robustly acquire driver's heart rate and heart rate variability analysis using a simple consumer-level webcam. More specifically, a real-time facial feature detector as well as a joint blind source separation method is used to capture the driver's facial blood volume pulse signal. Experimental results from both laboratory and actual road driving conditions demonstrate that the proposed non-contact framework is promising HR and HRV monitoring, even with the existence of unstable light source variation.
