IMAGE CORRECTION PROCESSING METHOD

摘要

: The present invention relates to distortion models consisting of two forward and backward reciprocating planes that let a corrected image correspond to an uncorrected image for each scanning direction. The models are constituted to let an uncorrected satellite image, scanned by a reciprocating scanning sensor, with scanning overlap or scanning underlap correspond to a corrected image after distortion correction by means of a continuous mapping function on a 1:1 basis. It is determined whether each point on the corrected image is a point on an overlapping scan or on an underlapping scan or on a normal scan from the existence of a real point on the distortion models.
