Abstract
A system for surveying a track includes two outer measuring devices and a central measuring device disposed therebetween, relative to the longitudinal direction of the track. Each measuring device has a specific position relative to the track in order to detect geometric track parameters. One outer measuring device includes a camera with a recording area in which a measuring object of the other outer measuring device and a measuring object of the central measuring device are disposed. The camera is connected to an evaluation device for pattern recognition. All of the position parameters of the track required for precise lining and levelling of the track are thus recorded by a single camera. A method of operating the system is also provided.
