Abstract

A surgical navigation system is provided. The surgical navigation system comprises a camera system comprising at least one camera. The camera system is capable of capturing images of light that is filtered through at least three different polarization angles. The surgical navigation system further comprises a processor having access to three dimensional image data of a surgical object. The processor is configured to determine first surface normals from the three dimensional image data of the surgical object. The processor is further configured to determine second surface normals from at least three images captured by the camera system of the surgical object under different polarization angles. The processor is configured to align the first surface normals with the second surface normals. Furthermore, a method for operating a surgical navigation system is provided.
