| Abstract | EROS, IKONOS and Quickbird are the three civilian satellites, which presently provide panchromatic images with the highest spatial resolution: 2-m, 1-m and 0.6-m, respectively. They also have off-nadir
viewing up-to-60º in any azimuth depending on the sensor, which enables stereo images (along and across track) to be acquired. However, the image acquisition system produces different geometric distortions, which need to be accurately corrected. The
paper reviews the image distortions and the different 3D models (non-parametric and parametric) for the geometric processing with their applicability to high-resolution images depending on the type of images and their pre-processing level. Results
are then presented with stereo images for the three sensors using different 3D models. In general, the 3D parametric models achieve more consistent results. |
