Cross-sensor image registration, orthorectification, and geopositioning of imagery are well-known problems whose solutions are difficult, if not impossible, to automate. Registration of radar to optical imagery typically requires a manual solution, as does the registration of imagery over rugged terrain or urban areas, where foreshortening and layover(More)
Small unmanned air vehicles (UAVs) provide an economical means of imaging large areas of terrain at far lower cost than satellites. Applications range from precision agriculture to disaster response and power line maintenance. Because small UAVs fly at low altitudes of approximately 100 meters, their cameras have only a limited field of view and must take(More)
Wide area motion imagery sensors utilize multiple cameras on a single aerial platform to monitor very large geographic areas in real time. The images must be stabilized and georegistered before they can be combined with other geospatial datasets, but their wide fields of view and oblique viewing angles make it difficult to align them accurately with a(More)
