More Information
Summary:Image data processing apparatus, including means for computing and accounting for lens distortion given two or more images of a scene and no other information. In particular, the image data processing apparatus of the invention produces one or more estimated lens distortion parameters for insertion in an epipolar constraint equation, the apparatus being arranged to adjust point correspondences between two or more captured images such that they lie on substantially the same epipolar curve.
