Abstract
Synthesis methods to create a stereo-mate of satellite imagery from an orthophoto have been developed in many previous studies. If these methods are applied in an urban area where there are many adjacent tall buildings, stereo viewing is inhibited by occlusion in the orthophoto and its stereo-mate. In high-resolution satellite imagery, the in-track view angle of the image is usually far from vertical; consequently, the occluded area near tall structures occupies a large area, and this severely affects stereo viewing. This study proposes a different approach to creating stereo-mates for high-resolution satellite imagery by projection of the digital surface model (DSM) draped by the original single image onto a fictitious satellite sensor model. The main benefit of this method is enhanced stereo viewing by arranging the fictitious sensor model to reduce occlusion area. The physical sensor model of the original image is previously derived by parallel projection model, and then the stereo-mate fictitious sensor model is determined from the physical sensor model.
