Abstract
A camera pose (position and orientation) estimation procedure is developed for application in navigated surgery. The procedure computes the camera’s position and orientation relative to a surface model of the patient’s face that is priorly acquired. Correspondences between tracked feature points in the camera video stream and three-dimensional points in the patient surface model allow constant computation of the camera’s position and orientation. With this transformation the camera is used as a measurement tool in navigated surgery and represents one of the core components in a novel surgical navigation system called Visual Navigation, an alternative to conventional optical and electromagnetic tracking systems.
