A landmark registration registers landmark points of navigation guidance information for performing a navigational guidance of a surgery procedure. The registration operation comprises a landmark point identification procedure and a landmark matching procedure. In particular, the present case is directed to automatically identifying three or more landmark points in an anatomy image by using a model according to shapes of a bone ridge depicted in the anatomy image. A graphical user interface enables interactively confirming locations of the three or more landmark points in the anatomy image. Given the identified three or more landmark points, the present case further describes interactively matching respective locations of the respective landmark points in the anatomy image with physical locations of a probe tip in anatomy according to deviation information of the probe tip. The automated identification and the interactive matching of landmark points enable generating navigational surgical guidance information with accuracy.
