Paper Abstract

An automated method is proposed for terrain height estimation from SPOT stereo pair images. This method consists of two procedures: registration between stereo pair images and terrain height estimation. In the first stage, stereo pair images are roughly rectified from initially selected 4 ground control point (GCP) pairs. Automated process is used for generating GCP pairs in the second stage. For the derivation of epipolar constraint, images are registered by piece-wise Affine transformation (ATF) using these GCP pairs. Accurate rectification is made by dynamic programming (DP) matching process applied to pair of epipolar lines. Terrain height is obtained from corresponding points on the stereo pair images by using a triangulation technique. Mean height error of this method is evaluated as less than 30 m.
