A device is proposed for measuring tracks, in particular for track laying machines, having two outer, one front and one rear, track-traveling measurement carriages (15, 21) and a middle track-traveling measurement carriage (22) arranged in between. To enable advantageous measurements, it is proposed that at least one position encoder (14, 20) pointing toward the middle measurement carriage (22) is associated with each of the outer measurement carriages (15,21), and at least two optical sensors (16, 17), in particular cameras, are arranged on the middle measurement carriage (22) on an optical axis (34) such that at least one optical sensor is oriented toward the rear measurement carriage (15) and at least one other optical sensor is oriented toward the front measurement carriage (21).
A device for measuring tracks for a track-laying machine having front and rear, track-traveling measurement carriages and a middle-track traveling measurement carriage arranged therebetween, said device comprising at least one position encoder pointing toward the middle measurement carriage and associated with each of the outer measurement carriages, and at least two optical sensors are arranged on the middle measurement carriage on an optical axis such that at least one optical sensor is oriented toward the rear measurement carriage and at least one other optical sensor is oriented toward the front measurement carriage.
