Abstract (en)
[origin: WO2010133966A1] The device comprises a measuring track (17) through which an object (1) is driven or moved, a laser (2) having a telecentric lens/Fresnel lens (3) for producing a perpendicular beam curtain (4) extending transversely to the measuring track (17). Furthermore, a camera (6) is arranged with an offset to the laser (2) in the longitudinal direction of the measuring track (17), likewise having a telecentric lens/Fresnel lens (7) placed in front. All light points of the laser light line (5) incident on the floor of the measuring track that are reflected undisturbed on the floor of the measuring track (17) are detected at an acute angle from the beam curtain (4) using said camera. Furthermore, means for detecting and recording the speed of the object (1) moved on the measuring track (17) through the beam curtain (4) are provided so that a distance-time diagram can be created. From the data thus obtained, the floor contour of the object can be determined, in other words, the shadow of the object on the floor resulting from the vertically incident light. The maximum height of the object is also determined using a light barrier arrangement.
