Abstract

An inexpensive, non-intrusive, vision-based, active fatigue monitoring system is presented. The system employs a single consumer webcam that is modified to operate in the near-IR range. An active IR LED system is developed to facilitate the quick localization of the eye pupils. Imaging software tracks the eye features by analyzing intensity areas and their changes in the vicinity of localization. To quantify the level of fatigue the algorithm measures the opening of the eyelid, PERCLOS. The software developed runs on the workstation and is designed to draw limited computational power, so as to not interfere with the user task. To overcome low-frame rate and improve real-time monitoring, a two-phase detection and tacking algorithm is implemented. The results presented show that the system successfully monitors the level of fatigue at a low rate of 8 fps. The system is well suited to monitor users in command centers, flight control centers, airport traffic dispatchers, military operation and command centers, etc., but the work can be extended to wearable devices and other environments.
