Abstract

For DEM estimation with stereo pair of images, a tie point matching is necessary between the two images, Nadir and Off-nadir viewing images. MTF degradations for both Nadir and Off-nadir viewing images are different so that matching accuracy is degraded in accordance with increasing of the off-nadir viewing angle. This proposed paper will discuss a MTF degradation due to atmospheric effect by means of an inverse Monte Carlo simulation together with an associated matching accuracy degradation. Further, a degradation on DEM estimation is also discussed.
