Abstract

This contribution compares two approaches for the geometric calibration of an optical coherence tomography (OCT) which forms part of a medical navigation system. For this purpose, a one step and a multi step calibration is performed with a self-produced 3D reference structure and a high-accurate 6 degrees of freedom (DoF) parallel robot, respectively. These 3D landmark-based geometric calibrations are based on the identification of a parameterized grey-box OCT model. We show in experimental results that both methods reduce systematic errors by more than one order of magnitude.
