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.
