1. A method for determining correspondences between a first image and a second image, comprising the steps of: obtaining a first image and a second image of a real environment; identifying a warping function between the first image and the second image; determining parameters of the warping function between the first and second images based on an image registration method; determining a third image by applying the warping function to the first image using the parameters; matching the third image and the second image to determine a matching result; and determining correspondences between the first and second images using the matching result and the warping function with the parameters.
