摘要
A method of recognizing an object in an image using multi-sensor integration through conditionally optimal geoscene generation and registration is provided. At least two images, one of which is a conditionally optimum, ortho-rectified base image, are input and used to generate a geoscene using at least two ground control points in a latitude-longitude geospatial domain. Georegistration of the geoscene produces a registered geoimage which may be output. A virtual geospatial information system database may be compiled from the georegistered images. A virtual transverse Mercator (VTM) projection is defined which allows processing images falling on both sides of the equator or across traditional UTM boundaries. An Affine transform is used for coordinate transformation in generating geoscenes. The georegistration process utilizes the union and the intersection of image pixels, and geolayering with interacting layers including geogrids and text layers, to define main body and background pixels to facilitate object recognition.
