Design of drowsiness, heart beat detection system and alertness indicator for driver safety

In the present scenario, the automobile usage rate is increasing. Consequently, the number of accidents is also increasing. According to research, the majority of the accidents are due to driver's carelessness. The main objective of this paper is to present a technology that reduces the accidents caused due to human abnormalities. This is done by monitoring the driver's head movements in order to detect drowsiness and heart beat rate by employing image processing techniques. Drowsiness detection is accomplished by head motion detection using frame difference algorithm and heart rate detection is carried out using R-peak detection algorithm. If any abnormalities are found during detection, an alert is given to the driver through a buzzer for the safety of the driver along with the passengers. As a preliminary approach, we are simulating the process using MATLAB.
