Abstract
The present application relates to an image processing apparatus and a method for matching and combining two map images with at least some overlap area. In some embodiments, color features of a first map image data and a second map image data are extracted and areas of matching color are determined. Border features in areas of matching color in the image data for the first and second maps may be extracted and map areas common to the first map image data and the second map image data may be determined based on the areas of matching color and the border features. Feature points of map areas common to the first and second maps may be extracted and the first map image data and the second map image data may be combined using common feature points.
