Embodiment Construction

[0023] exist figure 1 A device 1 for classifying motor vehicles 2 on a roadway 3 is shown in . The device 1 has a sensor 4 operating according to the light section method, which is mounted on a bridge 5 spanning the roadway 3 and is connected to an evaluation device 6 . The sensor 4 comprises on the one hand a light pattern projector 7 which projects a light pattern 9 onto the roadway 3 from a first position (here the upper support 8 of the bridge support 5); and the sensor on the other hand Comprising a camera 10 which captures an image 12 of the projected light pattern 9 from a second position (here the lower support 11 of the bridge support 5), as exemplified in figure 2 and 3 as shown in . The evaluation device 6 determines the surface contour of the vehicle 2 from the distortion of the light pattern 9 in the image 12 (such as this distortion occurs due to the surface topography of the vehicle 2 from the viewing angle of the camera 8 which is different from the directi...

Abstract

Device (1) for classifying objects (2), in particular vehicles, on a roadway (3), with a sensor (4), which operates according to the light-section procedure and is directed onto the roadway (3) to detect the surface contour of an object (2), and an evaluation unit (6) connected to the sensor (5) that classifies the object (2) on the basis of the detected surface contour.

Description

technical field [0001] The invention relates to a device and a method for classifying objects, in particular motor vehicles, on a roadway. Background technique [0002] The classification of objects on the roadway is of great importance for road toll systems or parking toll systems in order to be able to implement a class-dependent tariff pattern. Vehicles are currently classified using very different structures, such as induction rings embedded in the roadway, light barriers on the edge of the roadway or radar scanners or laser scanners installed above the roadway. The first configuration is only able to detect the dimensions of the vehicle, while the latter, although capable of detecting the entire surface contour of the vehicle as a 3D topography, is however technically complex and correspondingly expensive. Contents of the invention [0003] The object of the present invention is to create a method and a device for classifying objects which are simpler and less expens...
