METHOD OF RECOGNIZING AN OBJECT IN AN IMAGE USING iMaG AUTOMATED GEOREGSTRATION SYSTEM GENERATED MULTI-ORBIT SATELLITE IMAGERY WITH A CADSTRAL DATA BASED IMAGERY BASE

摘要

A method of generating a Virtual Geospatial Information System (VGIS) database for recognizing an object in an image. At least two images are input to the system, one of the images being a base image for scene registration. At least one orthoimage is generated with corresponding digital elevation model (DEM) data in a Virtual Earth Coordinate (VEC) System domain. The at least one orthoimage is registered to produce a registered image set. Georegistered imagery with scene content signatures is output for automated scene content analysis and automated change detection. In another embodiment, the method of generating a VGIS database for recognizing an object in an image includes the steps of: inputting at least two images, one of the images being a base image for scene registration; registering the at least one image in the virtual Earth or no-coordinate domain to produce a reduced drift geo-aligned image set; and outputting the geo-aligned imagery comprising at least one item chosen from a set of items consisting of: scene content signatures; signature libraries of the base images and the registered image set; georegistration variance score map; georegistration drift score database; and change detection.
