Correcting large lens radial distortion using epipolar constraint

It is necessary to correct lens distortion for building 3D models from multiple 2D images. Lens distortion is usually dominated by radial components, and especially dominated by the first radial distortion term that is called large lens radial distortion. In this work, we propose a method for correcting large lens radial distortion based on epipolar constraint. It requires nothing but a number of image point correspondences from two views, while the distortion center is assumed to be at the image center. Experimental results show that the robustness and correction accuracy of the proposed method outperform those of the previous methods.
