発明の名称 (英語) GAZE POINT DETECTION METHOD AND GAZE POINT DETECTION DEVICE コモンズ
発明の概要(英語) A gaze point detection device (1) is provided with two stereo cameras (2a, 2b) for capturing a face image of a subject (A), light sources (3a, 3b) provided on the outside of apertures (9a, 9b) of the stereo cameras (2a, 2b), control circuits (4, 5, 6), and an image processor (7). The image processor (7) calculates, on the basis of the face image, a vector (r) to a pupil from a cornea reflection point of the subject (A) in a plane perpendicular to a reference line of the stereo cameras (2a, 2b). The image processor (7) uses a function (f1) to calculate an angle (.theta.) of a line of sight of the subject (A) with respect to each of the reference lines and on the basis of the vector (r). The image processor (7) detects the gaze point (Q) of the subject (A) on a display screen by correcting the function (f1) and calculating the directions of the lines of sight calculated for the two stereo cameras (2a, 2b), in such a way that the directions of the lines of sight become close.
