Determining the Position of Head and Shoulders in Neurological Practice with the use of Cameras

Abstract

The posture of the head and shoulders can be influenced negatively by many diseases of the nervous system, visual and vestibular systems. We have designed a system and a set of procedures for evaluating the inclination (roll), flexion (pitch) and rotation (yaw) of the head and the inclination (roll) and rotation (yaw) of the shoulders. A new computational algorithm allows non-invasive and non-contact head and shoulder position measurement using two cameras mounted opposite each other, and the displacement of the optical axis of the cameras is also corrected.
