Instrument calibration for a camera based surgical navigation system

In this abstract, we present a system for mounting a single-camera to arbitrary surgical instruments and calibrating its position relative to the instrument. The camera is used for surgical navigation and can be covered with sterile foil due to a connection mechanism to the mounting system with magnets. The calibration of the cameras' position relative to the instruments' tool center point is done by a checkerboard based calibration procedure and using defined pivot points.
