GAZE DIRECTION DETECTION DEVICE, AND GAZE DIRECTION DETECTION METHOD

摘要

A gaze direction detection device according to the present technology includes a detector for detecting a gaze of a driver over a predetermined period of time, a determiner for outputting second gaze information indicating that the driver is gazing, from first gaze information detected by the detector, a generator for generating a gaze distribution from the second gaze information output by the determiner, and a corrector for correcting the first gaze information detected by the detector, where the corrector calculates a center of a reference distribution that is set in advance and a center of the gaze distribution generated by the generator, and causes the center of the reference distribution and the center of the gaze distribution to overlap each other, and then calculates a correction parameter based on a difference between the reference distribution and the gaze distribution, and corrects the first gaze information with the correction parameter.

1. A gaze direction detection device comprising:
a detector for detecting a gaze of a driver over a predetermined period of time; a determiner for outputting second gaze information indicating that the driver is gazing, from first gaze information detected by the detector; a generator for generating a gaze distribution from the second gaze information output by the determiner; and a corrector for correcting the first gaze information detected by the detector, wherein the corrector calculates a center of a reference distribution that is set in advance and a center of the gaze distribution generated by the generator, and causes the center of the reference distribution and the center of the gaze distribution to overlap each other, and then calculates a correction parameter based on a difference between the reference distribution and the gaze distribution, and corrects the first gaze information with the correction parameter.
