Abstract
A visual line detection device according to an embodiment includes a detection unit, an acquisition unit, a determination unit, a calculation unit, and a calibration unit. The detection unit detects a visual line direction of a driver in a vehicle. The acquisition unit acquires a running state of the vehicle. The determination unit determines whether or not the running state acquired by the acquisition unit is a gazing state where the driver is gazing at a particular position. The calculation unit calculates a representative value for a detection result of the detection unit in a case where the determination unit determines that the running state is the gazing state. The calibration unit executes calibration for detection of the visual line direction by the detection unit in such a manner that the representative value calculated by the calculation unit is a reference thereof.
