METHOD OF OBJECT LOCATION IN AIRBORNE IMAGERY USING RECURSIVE QUAD SPACE IMAGE PROCESSING

摘要

A method and computer workstation to determine the location in the ground space of a selected point in a digital image of the earth obtained by an airborne camera The image is associated with data indicating the geo-location coordinates for the points in the ground space corresponding to the image The method includes the steps of performing independently and in parallel a recursive partitioning of the image space and the ground space into successively smaller quadrants until a pixel coordinate in the image assigned to the selected point is within a predetermined limit of the center of a final recursively partitioned quadrant in the image space The method further includes a step of calculating a geo-location of the point in the ground space corresponding to the selected point in the image space The methods are also applied for determining geo-location from oblique reconnaissance imagery.
