1. A method for determining correspondences between a first and a second image, comprising the steps of: a) providing a first image and a second image of the real environment; b) defining a warping function between the first and second image; c) determining the parameters of the warping function between the first image and the second image by means of an image registration method; d) determining a third image by applying the warping function with the determined parameters to the first image; e) determining a matching result by matching the third image and the second image; and f) determining correspondences between the first and the second image using the matching result and the warping function with the determined parameters.
