In the head pose detection system based on 3D positions of the pupils and nostrils which are detected using two stereo-calibrated video cameras and near-infrared light sources, the nostril detection supports the pupil detection as well as the head pose detection. However, the shadows of the nose due to the illumination of the light sources tend to cause the false detection of the nostrils. In order to improve the nostril detection, the present paper proposes a geometrical method using the 3D domain determined as the nostril existable range relative to two pupils considering the horizontal and vertical eyeball rotation. The experimental results show the improvement of the nostril detection.
