Abstract
A system for measuring the position of a hand-held tool relative to a body in six degrees of freedom employs a camera attached via a mechanical linkage to the tool so that the camera moves together with the proximal portion of the tool and has a field of view including the distal end of the tool. A processing system processes images from the camera to determine a position of at least part of the tool. By employing optically identifiable fiducial reference points defined on the external surface of the body, a projection of the tool tip position onto a plane containing the target can be derived and displayed together with the target position, thereby facilitating guiding the tool to the target.
