Calibration and registration of an endoscope are important steps while using the endoscope for any augmented reality applications or for the recovery of 3D information from it during surgical procedures. Traditionally calibration and registration are done simultaneously just before surgery. In this paper we present a novel registration technique, following offline calibration, which is simple, fast and concurs with the ergonomics of an operating room. We are developing a new hybrid navigation system for the purpose of navigation in ventral spine surgeries where in the endoscope is calibrated once in several surgeries, but, it is registered by the proposed novel technique before every surgical procedure.
