1. Marker device for the measuring of wheel angles on vehicles with an electronic camera, in particular toe in, camber and thrust misalignment between wheels and body, comprising:

  • a supporting structure provided with fastening means enabling mounting on a vehicle perpendicular to the length axis of the vehicle and at each end being provided with at least three markers that are detectable by the camera, the three markers at each end being placed so that at least two have different positions relative to the length axis of the vehicle and at least two have different positions perpendicular to the length axis of the vehicle, the positions of the markers are well defined as to dimensions and configuration so that the marker device can serve as a base for parallelism and camera angles at a measuring of the wheel angles so that the measurements of the left and right side can be correlated.
