System and method of surveying a track

A system for surveying a track, the system comprising:

• two outer measuring devices disposed outwardly relative to a longitudinal direction of the track;
• a central measuring device disposed between said two outer measuring devices;
• each of said measuring devices occupying a specific position relative to the track for detecting geometric track parameters;
• one of said two outer measuring devices including a camera with a recording area;
• another of said two outer measuring devices having a measuring object disposed in said recording area;
• said central measuring device having a measuring object disposed in said recording area;
• and
• an evaluation device connected to said camera for pattern recognition;
• and
• said evaluation device being a computer with a pattern recognition and image evaluation software configured for recognizing the measuring objects and determining the position of the measuring objects relative to one another and with respect to an image section of the camera during movement of the system along the track.
