1. A computer implemented method for providing guidance to steer an endoscopic device towards one or more landmarks in a patient, the method comprising:
- determining a current position of a reference point on the endoscopic device relative to a reference frame;
determining a first vector from the current position of the reference point to a position of a first landmark relative to the reference frame;
transforming the first vector from the reference frame to an image reference frame that corresponds to the perspective of an image capturing device disposed at a tip of the endoscopic device; and
displaying a graphical representation of the transformed first vector along with and positioned relative to a current image captured by the image capturing device on a display screen so as to indicate a direction to steer the tip of the endoscopic device towards the first landmark.

Abstract
Landmark directional guidance is provided to an operator of an endoscopic device by displaying graphical representations of vectors adjacent a current image captured by an image capturing device disposed at a tip of the endoscopic device and being displayed at the time on a display screen, wherein the graphical representations of the vectors point in directions that the endoscope tip is to be steered in order to move towards associated landmarks such as anatomic structures in a patient.
