DETERMINATION APPARATUS AND DETERMINATION METHOD

摘要

A determination apparatus includes: a memory memorizing a three-dimensional face model in which a three-dimensional face shape and eye positions of a test subject, and change information mapping each state of change in eye shape to each shape parameter are registered; a matching unit matching a picked-up image of a driver picked up by an image pickup device with the three-dimensional face shape to specify the eye position; a shape parameter determination unit changing the shape parameter to specify a shape parameter corresponding to the eye state in the picked-up image; an eye-opening degree calculating unit calculating an eye-opening degree indicating a state of opening of the eye in the picked-up image; and a determination unit determining a state of a face and an eye of the driver on the basis of the eye-opening degree and the specified shape parameter.

1. A determination apparatus comprising:
a memory configured to memorize a three-dimensional face model in which a three-dimensional face shape of a test subject, eye positions of the test subject, and change information that maps each state of change in eye shape to each shape parameter are registered; a matching unit configured to match a picked-up image of a driver picked up by an image pickup device with the three-dimensional face shape to specify the eye position; a shape parameter determination unit configured to change the shape parameter to specify a shape parameter corresponding to the eye state in the picked-up image; an eye-opening degree calculating unit configured to calculate an eye-opening degree indicating the state of opening of the eye in the picked-up image; and a determination unit configured to determine the state of driver's face and eye on the basis of the eye-opening degree and the specified shape parameter.
