Comprehensive system for the evaluation of the attention level of a driver

摘要

Nowadays, monitoring the attention level of a driver is a useful tool for assuring a better degree of safety aboard motor vehicles. Recent literature reports different technologies that have been explored for evaluating various critical physical parameters of drivers. This paper presents an attempt to integrate different non-intrusive monitoring systems which include an eye-blink detection system which works by means of a camera and head-position monitoring system based on an ultrasonic transmitter/receiver network. The information retrieved by the comprehensive system will be of help either for the evaluation of the driver's condition or for boosting other devices often placed in the car such as an alcohol detection system which can pick up dangerous head positions. Two separate algorithms have been implemented and the experiment will be presented in order to validate the proposed systems and algorithms.
