The invention relates to a rapid rearrangement method of satellite stereoscopic image approximate epipolar lines based on projection trajectory, on the basis of the theory of projection trajectory, based on the approximate linearity and local linearity of the satellite image trajectory within an image range, straight line pairs are adopted to express each pair of homonymic epipolar curved lines in a simplifying way. The approximate epipolar line image is generated based on the method, and the method has the characteristics of simpleness, practicability and strong popularity. The experimental results of satellite stereoscopic images of various terrian conditions show that; the method can generate sub-pixel vertical parallax approximate epipolar line images under the condition that the orientation parameters of the image has high precision; currently, the method is successfully applied to stereoscopic updating of the satellite image and a DEM automatic generation software module and hashigh application value. The correctness, feasibility and popularity of the method are proved.
