Track measuring vehicle and method for measuring the compliance of a track

Abstract

The invention relates to a track measuring vehicle (1) for measuring the compliance of a track (7), comprising a machine frame (3) supported on rail bogies (4) and movable on the track (7), and a measuring carrier (13) spaced at a longitudinal distance from the respective rail bogie (4), on which a distance sensor (14) for measuring a vertical distance (a1) of the unloaded track (7) is arranged. An optical marker (16) is arranged on at least one rail bogie (4), the measuring carrier (13) being coupled to a camera (15) whose recording area (17) is directed towards the optical marker (16), and an evaluation unit (18) for determining a track depression (9) based on the combined processing of data from the distance sensor (14) and data from the camera (15) is provided.Thus, the track depression (9) at the respective track location is determined from the determined relative positions of the rail bogie (4) and the measuring carrier (13).
