    • A face horizontal direction measuring unit measures the angle of the face horizontal direction for a face image obtained by an imaging unit. By using information on the radius of the head and information on the shoulder position of the person obtained by the aforementioned measurement, a face vertical displacement measuring unit measures a face displacement in the vertical direction not affected by a head posture. According to the obtained displacement, the face angle in the vertical direction is decided. By using the obtained face direction, the angle of the gaze in the horizontal direction and the eyeball radius are measured. Further, a gaze vertical displacement measuring unit is provided for which measuring the pupil center position against the eyeball center position as the gaze displacement in the vertical direction. This displacement amount is used to measure the gaze angle in the vertical direction.
    • 面部水平方向测量单元测量由成像单元获得的面部图像的脸部水平方向的角度。 通过使用关于头部的半​​径的信息和通过上述测量得到的人的肩位置的信息,面部垂直位移测量单元测量不受头部姿势影响的垂直方向的面部位移。 根据获得的位移,决定垂直方向的面角。 通过使用所获得的面部方向,测量注视在水平方向上的角度和眼球半径。 此外,提供了一种注视垂直位移测量单元,其用于测量瞳孔中心位置抵靠眼球中心位置作为垂直方向上的视线位移。 该位移量用于测量垂直方向上的视线角度。
