Title: METHOD FOR TRACK POSITION MEASUREMENT USING A LASER SCANNER, DETECTING MACHINE FRAME DEFORMATION BY MEANS OF STRAIN GAUGES
Abstract:
A track position measurement system (9) for correcting track positions is composed of a machine frame (3) and a number of track position measuring devices (10) that acquire the position of the track (4). Said track position measuring devices (10) include laser scanners for non-contactingly scanning the track (4) and are connected to the machine frame (3), which is used as reference for the measurements, in such a way as to be invariable in relation to a vertical.
