A method for verifying a character to be displayed on a screen , compared to a reference character , the character to be displayed and the reference character each comprising at least several characteristic points to be displayed on the screen , the method being characterized in that it comprises the following steps: a) determining a barycenter (G1) of the characteristic points of the character to be displayed , b) computing geometric coordinates of each characteristic point of the character to be displayed in a coordinate system centered on the determined barycenter (G1), and c) computing a deviation (E) between the character to be displayed and the reference character , as a function of the computed geometric coordinates for the character to be displayed and predetermined geometric coordinates for the reference character , said predetermined geometric coordinates being geometric coordinates of the characteristic points of the reference character in a coordinate system centered on a barycenter (G2) of its characteristic points , the character to be displayed being considered correct only if the computed deviation (E) is below the predetermined threshold (S), the character to be displayed and the reference character each comprising at least one segment to be displayed on the screen , the characteristic points of said character corresponding to end of the at least one segment . the character to be displayed and the reference character each comprising at least several characteristic points to be displayed on the screen , the method being characterized in that it comprises the following steps: a) determining a barycenter (G1) of the characteristic points of the character to be displayed , b) computing geometric coordinates of each characteristic point of the character to be displayed in a coordinate system centered on the determined barycenter (G1), and c) computing a deviation (E) between the character to be displayed and the reference character , as a function of the computed geometric coordinates for the character to be displayed and predetermined geometric coordinates for the reference character , said predetermined geometric coordinates being geometric coordinates of the characteristic points of the reference character in a coordinate system centered on a barycenter (G2) of its characteristic points , a) determining a barycenter (G1) of the characteristic points of the character to be displayed , b) computing geometric coordinates of each characteristic point of the character to be displayed in a coordinate system centered on the determined barycenter (G1), and c) computing a deviation (E) between the character to be displayed and the reference character , as a function of the computed geometric coordinates for the character to be displayed and predetermined geometric coordinates for the reference character , said predetermined geometric coordinates being geometric coordinates of the characteristic points of the reference character in a coordinate system centered on a barycenter (G2) of its characteristic points , the character to be displayed being considered correct only if the computed deviation (E) is below the predetermined threshold (S), the character to be displayed and the reference character each comprising at least one segment to be displayed on the screen , the characteristic points of said character corresponding to end of the at least one segment . <EOS>
