Abstract
Systems and methods are disclosed for an automated touchless registration of patient anatomy for surgical navigation systems. An example method includes: acquiring a plurality of images of the patient; determining relevant objects from a plurality of poses; and processing the received images through a photogrammetry module. The photogrammetry module may provide camera calibration and facilitate camera registration. As such, manual movement or robotic movement capabilities of the camera head, and digital visualization capabilities of a digital surgical microscope disclosed herein can be extended to allow near-automated or fully automated touchless registration for traditional surgical navigation.
