SYSTEM FOR ASSOCIATING PRE-RECORDED IMAGES WITH ROUTING INFORMATION IN A NAVIGATION SYSTEM
First Claim
1. An automated method of using pre-recorded images as part of a computerized navigational system to acquaint a user with intersections and other points of interest along a selected route, comprising:
- selecting a set of landmark images from a multiplicity of pre-recorded images; and
processing the selected landmark images with header information to associate the selected landmark images to a set of spatial nodes based on a plurality of pre-defined routing runs such that the automated navigation system can separately process the selected route and the set of landmark images by using the header information associated with the set of landmark images.

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.

3. An automated navigation system that displays selected ones of pre-recorded images to acquaint a person with intersections and other points of interest along a selected route, comprising:
-
an image database containing a set of landmark images selected from a multiplicity of pre-recorded images, the set of landmark images including header information processed to associate the landmark images to a set of spatial nodes based on a plurality of pre-defined routing runs;
a routing database;
means for generating a desired routing run using the routing database means for displaying images associated with the routing run by separately processing the image database based upon the header information associated with the set of landmark images contained in the image database.

5. A method of using pre-recorded images as part of an automated navigational system to acquaint a user with approaching intersections and other points of interest, comprising:
-
creating a set of routing runs correlating to a path or road segment to be traveled, whereby a transition point from one run to another is defined by a spatial node;
selecting a set of images corresponding to landmarks along the roadway system from a multiplicity of pre-recorded images;
processing the set of selected images to generate header information to associate the images with the spatial nodes based on the routing runs;
recording the processed images and the header information in an image database. - View Dependent Claims (6, 7, 8, 9, 10, 11)
