Method for determining a driver's vigilance level

摘要

The present invention relates to a method for determining a state of alertness of a driver in a vehicle (1) from a predetermined image analysis algorithm. The method notably comprises a step of executing the predetermined algorithm on said sequence of images generated in order to detect a series comprising at least one movement of the driver's head (2), a step of determining the speed and / or the amplitude of each identified movement as well as the dynamic and static periods of the driver's head, a step of detecting the dynamic and static periods of the driver's head and of measuring the frequency and duration of each period and a step of determining a state of alertness of the driver (2) from the speed and / or the amplitude determined for each movement identified and the frequency and duration of each period detected.
