VISUAL LINE DIRECTION DETECTION METHOD OR APPARATUS FOR VEHICLE DRIVER

摘要

PROBLEM TO BE SOLVED: To provide a highly reliable visual line vector detection method or apparatus performing correction of the measured result of a visual line direction (visual line vector) with an individual difference taken into consideration.

SOLUTION: The method of obtaining the visual line direction of a vehicle driver comprises the steps of: obtaining the measured value of the visual line angle in a vertical direction within prescribed time of the driver; obtaining the median of the measured value; obtaining a difference amount between the median of the vehicle driver and the median of a standard driver; applying the correction of the difference amount to the median of the visual line angle in the vertical direction of the vehicle driver; and determining the visual line vector of the vehicle driver on the basis of the corrected median.
