摘要：Systems, devices, features, and methods for constructing a graphic model of ageographic object, such as a road sign or features thereof, from an image, such as, for
example, to develop a navigation database are disclosed. For example, one methodcomprises receiving a plurality of images of regions, such as of roads or paths. An imageof the plurality of images is identified. A process to determine scale-invariantcomponents of a geographic object in the identified image may be performed. Otherprocesses, such as generating a dictionary to facilitate optical character recognition maybe performed. A graphic model of the geographic object is generated based on thescale-invariant components and/or the optical character recognition. The generatedgraphic model may be associated with a navigation or map database.
