20-3 Face Pose Estimation by 3D Position Detection of Pupils and Nostrils

Abstract

3D positions of pupils and nostrils were detected using infrared light sources and two stereo cameras. Nostril detection in the image was supported by our robust pupil detection technology. The experimental results showed that head direction detection was possible for a horizontal large angle of the head, ±45 deg, by estimating the undetected nostril position from the metrics data obtained from initial calibration procedure.
