Map Feature Extraction Using Overhead View Images

Abstract:

The present invention relates to a method of generating an overhead view image of an area. More particularly, the present invention relates to a method of generating a contextual multi-image based overhead view image of an area using ground map data and field of view image data. Various embodiments of the present technology can include methods, systems and non-transitory computer readable media and computer programs configured to determine one or more images of a generated overhead view of the geographical area, wherein the generated overhead view is generated from aggregated pixel values determined from correlated pixel values in each of a plurality of images of a geographical area; identify one or more semantic map features as being present in the one or more images of the overhead perspective of the geographic area; extract the one or more semantic map features of the geographical area from the one or more images of the substantially overhead perspective of the geographical area; and translate the extracted semantic map features to a semantic map layer of a geometric map associated with the geographical area.
