Title Point-of-gaze detection device, point-of-gaze detecting method, personal parameter calculating device, personal parameter calculating method, program, and computer-readable recording medium
Abstract A point-of-gaze detection device according to the present invention detects a point-of-gaze of a subject toward a surrounding environment.
The device includes: an eyeball image obtaining means configured to obtain an eyeball image of the subject; a reflection point estimating means configured to estimate a first reflection point, at which incoming light in an optical axis direction of an eyeball of the subject is reflected, from the eyeball image; a corrected reflection point calculating means configured to calculate a corrected reflection point as a corrected first reflection point by correcting the first reflection point on the basis of a personal parameter indicative of a difference between a gaze direction of the subject and the optical axis direction of the eyeball; and a point-of-gaze detecting means configured to detect the point-of-gaze on the basis of light at the corrected reflection point and light in the surrounding environment.
