More Information
Summary:The invention discloses a sight tracking and fatigue early warning method, and belongs to the technical field of intelligent traffic. The method comprises the step of obtaining the information of the driver face through a mini-type camera, the step of controlling starting and stopping of a near axial infrared controllable light source and a far axis infrared controllable light source, the step of starting the near axial infrared controllable light source at the odd number frame, the step of starting the far axis infrared controllable light source at the even number frame, and the step of determining the position of the human eye pupils in a video sequence after the difference calculation according to the human eye pupil reflection characteristics. After the pupil positioning through the image difference frequency is carried out based on an infrared effect under infrared light, the sight projection position is reversely calculated according to the pupil center position and the feature recognition points of a v
