NAVIGATIONAL AID HAVING IMPROVED PROCESSING OF DISPLAY DATA

摘要

The present invention relates to the processing of display data on a screen for a navigational aid between a current position point (POCS) and a destination point (DEST). The display on the screen comprises at least one 3-D representation of a panorama facing the position point. The invention provides for: a step of comparing a distance from the current position point with at least one threshold distance (DS1; DS2), and a step of processing display data, according to said comparison, in order to control a command of the display on the screen with at least, respectively from the bottom to the top of the screen: a first 3-D representation, according to a perspective defined with a first angle of view in relation to a selected plane, of a panorama separated from the current position point by a distance that is less than said threshold distance (DS1; DS2); and a second representation, according to a perspective defined with a second angle of view in relation to said selected plane, of a panorama separated from the current position point by a distance that is greater than said threshold distance (DS1; DS2), the first angle being smaller than the second angle.
