The invention relates to a method for making a three-dimensional reproduction of a relief surface, which method comprises the following steps: scanning the surface at least twice by means of a scanner to be connected to a computer, the first scan being carried out under different conditions than the second scan, comparing the scans with each other by means of the computer in order to obtain a digital three-dimensional image of the surface relief, forming a mould by means of a processing machine on the basis of said digital three-dimensional image of the surface relief, making the three-dimensional reproduction of the surface by means of said mould.
