SYSTEM AND METHOD FOR PROVIDING A CONTOUR VIDEO WITH A 3D SURFACE IN A MEDICAL NAVIGATION SYSTEM

摘要

A medical navigation system for displaying a three dimensional (3D) surface video of a target is provided. The medical navigation system comprises a 3D imaging device, a camera, a display, and a controller electrically coupled to the 3D imaging device, the camera, and the display. The controller has a processor coupled to a memory. The controller is configured to perform calibration of input devices; acquire 3D depth data of the target from a signal generated by the 3D imaging device; construct a 3D surface contour of the target based on the 3D depth data; acquire a video stream of the target from a signal generated by the camera; generate a 3D surface video based on the 3D surface contour and the video stream; and display the 3D surface video on the display.
