A reflexive eye movement evaluation device is provided for a vehicle, and includes: a reflexive eye movement estimating unit that receives a vehicle exterior video including a visual target of a subject and a vehicle interior video including the subject, the vehicle exterior video and the vehicle interior video being captured by an imaging unit, measures a visual target movement of the subject using the vehicle as a fixed coordinate system from the vehicle exterior video, measures a head movement of the subject from the vehicle interior video, and estimates a reflexive eye movement of the subject; an eye movement measuring unit that measures an eye movement of the subject from the vehicle interior video; and an evaluation value calculating unit that calculates an evaluation value for the reflexive eye movement from the estimated reflexive eye movement and the measured eye movement.

Reflexive eye movement evaluation device, reflexive eye movement evaluation system, and reflexive eye movement evaluation method

An attentiveness determination device includes an image processing unit, a pupil distance calculation unit, a heterophoria detection unit, and an attentiveness determination unit. The image processing unit outputs first reference coordinates, second reference coordinates, first pupil coordinates, and second pupil coordinates. The pupil distance calculation unit calculates at least one position component of the first pupil coordinates with respect to the first reference coordinates and at least one position component of the second pupil coordinates with respect to the second reference coordinates. The heterophoria detection unit outputs a heterophoria detection result indicating a state of a first eyeball and a second eyeball. The attentiveness determination unit determines attentiveness of a person according to the heterophoria detection result.

An eye tracking device according to the present disclosed technology includes: an image acquiring unit that acquires an image of a subject; an arithmetic processing unit that performs image processing; and a line-of-sight angle calculating unit that calculates a line-of-sight direction vector on the basis of a result of the image processing. The arithmetic processing unit includes: a real image arithmetic processing unit that performs arithmetic processing on a real image in an image space; and a three-dimensional model superimposition processing unit that performs superimposition processing on the image space using a three-dimensional face model. The three-dimensional model superimposition processing unit includes a three-dimensional model correcting unit that corrects the three-dimensional face model in order to eliminate an error caused by the superimposition processing.
