Abstract: A surgical system and method for markerless intraoperative navigation is provided. The system can includes a structured light system that can be utilized to intraoperatively sense three-dimensional surface geometry. The computer system is configured to segment a depth image to obtain surface geometry data of an anatomical structure embodied within the depth image, register the surface geometry data of the anatomical structure to a model, and update the surgical plan according to the registered surface geometry data. The surgical system is an endoscopic surgical system.

Abstract: A system for an endoscope includes a camera head coupled to an optical channel. The system also includes a light port coupled to the endoscope and configured to receive a first light ray, wherein the first light ray travels through a first optical path along an optical axis of the optical channel. The system also includes a depth measurement module coupled to the endoscope, wherein the depth measurement module is configured to transmit a second light ray through a second optical path along the optical axis. The system also includes an image sensor coupled to the camera head and configured to receive a first set of images pertaining to the first light ray and a second set of images pertaining to the second light ray. The system also includes a processing device configured to use the first and second sets of images to generate one or more 3-D images.
