Beschreibung
Zusammenfassung:	A method of measuring a height of a vehicle on a road comprises recording with a vehicle classification sensor a 3D representation of the vehicle passing the section and recording with a camera a 2D image of at least an upper portion of the vehicle and a background; determining an edge profile between the upper portion and the background establishing a fan of rays each extending from the elevated point and through a different one of multiple points along the edge profile; shifting the 3D representation in the coordinate system in height until it is tangent to said fan; and determining said height of the vehicle from the shifted 3D representation in the coordinate system. The disclosed subject matter further relates to an apparatus for performing this method.
