PROBLEM TO BE SOLVED: To provide a sight line measurement device capable of measuring a wide range of sight line.SOLUTION: A sight line measurement device comprises: means for acquiring a corneal curvature radius (R) of right and left eyeballs, and a distance (K) between a corneal curvature center and a pupil center, from two light source reflection lights reflected on the pupils and the corneal surfaces of the right and left eyeballs of an observer, by using two sets of cameras for photographing the eyeballs of the observer and a light source; means for calculating an optical axis by calculating a corneal curvature center position and a pupil center position, based on the detected two light source reflection lights, the corneal curvature radius (R) obtained by calculation beforehand, and the distance (K), when two light source reflection lights are detected in one camera means, and the light source reflection light is not detected in the other camera means; and means for calculating a gazing point based on the optical axis calculated in the right and left eyeballs, respectively.SELECTED DRAWING: Figure 6

    【課題】広範囲の視線を計測できる視線計測装置を提供する。【解決手段】観測者の眼球を撮影するための2組のカメラと光源を用いて、観測者の左右の眼球の瞳孔と角膜表面で反射する各2つの光源反射光から、左右の眼球の角膜曲率半径(R)と、角膜曲率中心と瞳孔中心との距離(K)を取得する手段と、一方のカメラ手段には2つの光源反射光が検出され、他方のカメラ手段には光源反射光が検出されない場合には、検出された2つの光源反射光、予め算出した角膜曲率半径(R)および距離(K)に基づいて、角膜曲率中心位置と瞳孔中心位置を算出して光軸を算出する手段と、左右の眼球においてそれぞれ算出された光軸に基づいて注視点を算出する手段を備える。【選択図】図6
