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 plurality of 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 plurality of eye-gaze points to the image coordinate system; and
a concentration determination processor configured to;
determine the concentration of the driver on the image coordinate system based on the concentration information,calculate at least one or more of an average value of an eye-gaze movement speed, a dispersion value of the positions of the plurality of eye-gaze points, or an area value of the plurality of eye-gaze points from the concentration information of each of the plurality of eye-gaze points, anddecide a line connected between a first eye-gaze point and a last eye-gaze point in a monitoring unit pattern among the plurality of eye-gaze points as a reference line and calculate the dispersion value of the positions of the plurality of eye-gaze points using distances between the reference line and the plurality of eye-gaze points.
