Epipolar Resampling of High Resolution Satellite Images Using Rational Polynomial Coefficients

Abstract:   (4417 Views)
An ongoing challenge in high-resolution satellite image (HRSI) processing has beenthe establishment of accurate epipolar geometry over the entire HRSI image area, which is a pivotal step of any stereo-image processing, including 3D topographic mapping. However, thepush broom camera which is used by most high-resolution satellites does not produce straight epipolar lines. Furthermore, in contrast to the well-known frame cameras, the epipolar curve pair does not exist for the entire stereo image area. Theseproperties make it difficult to establish the epipolar geometry of a push broom camera, resulting in a limited accuracy of the epipolar image resampling. In this study, a new method of epipolar curve pair determination and epipolar image resampling of space bornepush broom imagery, based on the popular RPC (Rational Polynomial Coefficients), is proposed
