| 摘要 |
The invention relates to a method for measuring tracks in relation to a measuring plan of the track which contains the actual position of the track, in relation to an absolute coordinate system. A measuring platform ( 2 ) is guided along the track ( 1 ), whereon an inertia platform ( 6 ) is arranged, which is initialised, respectively, calibrated to the beginning of the measurement and is aligned in relation to the coordinate system. The inertia platform ( 6 ) detects the respective positions of the measuring platform ( 2 ) in relation to the coordinate system during the journey of the measuring platform ( 2 ). Positional data of the inertia platform ( 6 ) is periodically examined based on fixed points ( 9; 9 ') which are arranged in the vicinity of the track and deviations in relation to the coordinate system are corrected by novel calibration, respectively, alignment.
