In order to determine the position of a fixed track point, the fixed track point is connected to a three-dimensional scanning aid (12), which has a shape that significantly deviates from a track environment and that spatially enlarges the fixed point (9). The track environment is permanently scanned by a rotating laser (5), which is continuously moved along the track, and registered as a point cloud. The characteristic form of the scanning aid (12) is determined from the point cloud by means of software, the location of the associated fixed point (9) in relation to the track (3) is automatically calculated, and possible correction values are registered as the difference between the target location and actual location of the track. |
