Paper Abstract

Methods for correcting scanned remote sensing images for distortions due to undesirable aircraft motion are presented. The methods are intended for correcting distortions due to yaw and roll of the aircraft during image acquisition. The aircraft motion is estimated by analyzing the distortion of the scanned image. The correction of the distorted image is then based on the estimated motion. The correction is based only on the distorted image itself, and there is no need for any additional side information. This makes the methods presented well suited for correction of existing data, but the methods can also be used in real time correction during image acquisition. The effectiveness of the correction methods is demonstrated by examples using both real data, and synthetic data with known distortions.
