Abstract

A method of enhancing positioning of a moving vehicle based on visual identification of visual objects, comprising obtaining from a location sensor a global positioning and a movement vector of a moving vehicle, capturing one or more images using one or more imaging devices mounted on the moving vehicle to depict at least partial view of a surroundings of the moving vehicle, analyzing the image(s) to identify one or more visual objects having a known geographical position obtained according to the global positioning from a visual data record associated with a navigation map, analyzing the image(s) to calculate a relative positioning of the moving vehicle with respect to the identified visual object(s), calculating an enhanced positioning of the moving vehicle based on the relative positioning and applying the enhanced positioning to a navigation system of the moving vehicle.

A computer implemented method of enhancing a navigation map by supplementing the map with visual data of a plurality of objects, comprising:

analyzing at least one image to identify a first object included in the plurality of objects depicted in the at least one image;
determining a geographical position of the first object based on a geographical position of a reference point of the at least one image and a position of the first object in the at least one image relative to the reference point, wherein the reference point is a center of the at least one image or a corner of the at least one image;
updating a map with a visual data record comprising at least one visual attribute of the first object and the geographical position of the first object;
and
storing the updated map with the visual data record in a database.
