Abstract

A method for aligning a measuring device installed alongside a roadway at an unknown installation height, the measuring device including a laser scanner, a camera and a display. A camera image generated by the camera is inserted into the display and superimposed by a road model, formed from a multiplicity of straight lines running towards an intersection point. The measuring device is subsequently rotated and tilted, as a result of which the camera image is rotated and shifted on the display, until the images of the roadway margins and edges running parallel thereto are in alignment at the intersection point.
