Abstract:
1. A navigation method to be implemented by a navigation apparatus that is capable of image-capturing and that has a display device, said navigation method comprising the steps of: a) obtaining current location information associated with the navigation apparatus, and location information of a reference target along a planned route that is being traversed; b) capturing real-time navigation images of the planned route according to an image-capture configuration parameter, wherein the image-capture configuration parameter specifies the focal length at which the navigation images are captured by the navigation apparatus; c) obtaining a display screen position associated with the reference target with reference to the current location information, the target location information, and the image-capture configuration parameter; and d) showing on the display device the navigation images together with a mark corresponding in position to the display screen position; wherein: the location information includes coordinates and altitude of the reference target; the current location information includes coordinates, altitude, and navigation bearing of the navigation apparatus; and in step c), the display screen position is obtained from the image-capture configuration parameter, the navigation bearing, a difference in the coordinates included in the location information and the current location information, and a difference in the altitudes included in the location information and the current location information.
