APPARATUS FOR DETERMINING CONCENTRATION OF DRIVER, SYSTEM HAVING THE SAME, AND METHOD THEREOF
First Claim
1. An apparatus for determining a concentration of a driver, the apparatus comprising:
- a region-of-interest definition processor configured to define a region-of-interest based on traffic-related information on front image information of a vehicle running;
a driver eye-gaze detection processor configured to detect a plurality of eye-gaze points from driver image information of a driver in accordance with an eye-gaze movement of the driver;
a driver concentration information calculation processor configured to calculate concentration information of each of the eye-gaze points;
an image coordinate system processor configured to convert the region-of-interest to an image coordinate system and convert positions of the eye-gaze points to the image coordinate system; and
a concentration determination processor configured to determine a concentration of the driver on the image coordinate system based on the concentration information.

13. A system for determining a concentration of a driver, the system comprising:
-
an image acquisition device configured to acquire a vehicle front image and a driver facial image; a driver concentration determination processor configured to detect an eye-gaze movement of the driver from the driver facial image, calculate concentration information with respect to each eye-gaze point of the driver, and determine the concentration of the driver based on the concentration information; and an output configured to output a concentration guide warning alarm to the driver when the concentration of the driver is determined to be smaller than a reference value by the driver concentration determination processor. - View Dependent Claims (14, 15, 16, 17)

18. A method for determining a concentration of a driver, the method comprising steps of:
-
defining a region-of-interest based on traffic-related information on front image information of a vehicle running; detecting a plurality of eye-gaze points from driver image information of a driver in accordance with an eye-gaze movement of the driver; calculating concentration information of each of the eye-gaze points; converting the region-of-interest to an image coordinate system and converting positions of the eye-gaze points to the image coordinate system; and determining a concentration of the driver on the image coordinate system based on the concentration information. - View Dependent Claims (19, 20)
