Claim 7:
8. A navigation system comprising:
a control circuit configured to:
determine a geographic location, of a vehicle, when a global positioning location is blocked by an obstruction, wherein the geographic location is determined by an in-vehicle location sensor,
extract an image line from a surrounding image by using an artificial intelligence model, wherein the surrounding image is from an in-vehicle image sensor,
transform an image coordinate of the image line to a world coordinate of a proximity map of a high definition (HD) map local storage based on the geographic location,
extract a map line from the HD map local storage based on the world coordinate,
determine a pose relationship between the image line and the map line, wherein the image line and the map line are paired and classified as either horizontal or vertical, and
generate a map-related location for the vehicle based on both the geographic location and the pose relationship; and

an interface circuit configured to communicate the map-related location for display on a user interface.
