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