Camera-based heart rate monitoring in highly dynamic light conditions

Recent advances in biomedical engineering have shown that heart rate can be monitored remotely using regular RGB cameras by analyzing minute skin color changes caused by periodic blood flow. In this paper an infrared-based alternative for light-robust camera-based heart rate measurements suitable for automotive applications is presented. The results obtained by this system show high accuracy (RMSE <; 1BPM under discolight) and a correlation score above 0.99 when compared with a reference measurement method. The proposed system enables new applications in the automotive field, especially since heart rate measurement can be integrated with other camera-based driver monitoring solutions like eye tracking.
