Measurement of a track position is carried out in successive measurement sections (15), wherein the relative track position is registered in each case with the aid of a long chord (17), formed by a laser beam (16), which serves as reference line of a measuring system (9). During this, an angle enclosed by the two long chords (17) of two successive measurement sections (15) is measured in order to thereby obtain a spatial curve reproducing the actual position of the track.

La présente invention concerne un procédé de mesure de la géométrie d'une voie par tronçons de mesure successifs (15). À cet effet, pour enregistrer la géométrie relative de la voie, on s'aide d'une corde géométrique (17) matérialisée par un rayon laser (16), utilisée comme alignement de référence d'un système de mesure (9). En l'occurrence, on mesure l'angle formé entre deux cordes géométriques (17) de deux tronçons de mesure successifs (15), ce qui permet de déterminer une courbe tridimensionnelle reflétant la position réelle de la voie.
