Description
Summary:Epipolar rectification aims at resampling stereoscopic images so that conjugate points are located along the same horizontal x-axis. For most stereoscopic digital surface model production algorithms, this rectification is a necessary preprocessing task because it allows reducing the 2D matching to a 1D matching problem. Most epipolar rectification algorithms exist in literature and are mainly for a given type of sensor (frame camera or push-broom sensor). In this paper, we present a generic method for epipolar rectification. This means that the method is applicable for both frame and push-broom cameras. The only difference lies in the projection function used to generate epipolar curves.
