Abstract

A vehicle navigation system uses prerecorded intersection images to more quickly and efficiently acquaint the driver with approaching intersections and other points of interest as part of a navigation system. The pre-recorded images are recorded, selected and processed with header information that associates the selected landmark images of approaching intersections and other points of interest to spatial nodes based on runs defined by routing information in the navigation system. The runs defined by the routing information correlate to a path or road segment to be traveled with the spatial nodes defining a transition point from one run to another, such as a roadway intersection where a turn is required to follow the routing information. Preferably, a multiplicity of recorded images are analyzed from a road segment to select a set of images that correspond to a plurality of distances from an approaching intersection, for example, where the selected images include a view of relevant visual information, such as road sign images, associated with the intersection.
