Abstract
This article presents a one step geometric calibration for an optical coherence tomography (OCT) which forms part of a medical navigation system. The 3D landmark-based geometric calibration with a self-produced 3D reference structure is based on the identification of a parameterized grey-box OCT model. We show in experimental results by comparing common measurement errors in the field of medical surgery before and after calibration, that the proposed methodology reduces systematic errors by more than one order of magnitude. Due to its simplicity, the calibration can be carried out directly before a surgical intervention enhancing the OCT accuracy.
