Claim Text:
1. A computer-implemented method for processing a distorted wide angle image with a barrel distortion, the method comprising the steps of: determining, on a basis of a mapping function representing a distortion of said distorted image, a reconstruction function representing a position of points of a reconstructed image as a function of a position of points of said distorted image and a scale coefficient, determining a plurality of different viewing angles, for each viewing angle of the plurality of different viewing angles generating a reconstructed image comprising the points of said distorted image comprised within, said viewing angle and reconstructed using said reconstruction function with a different scale coefficient for each of said reconstructed images; wherein each of said reconstructed images has its central point corresponding to the same point of said distorted image; identifying coordinates of an object on one of said reconstructed images as a function of coordinates of that object on another one of said reconstructed images and a quotient of scale coefficients of the reconstruction functions used for generating that reconstructed images.
