A measuring station system for calibrating a reference system for vehicle measurement has at least one image recording device, a calibration device having multiple calibration device reference features, and a calibration frame having at least three support points which are designed for accommodating a reference system carrier for the reference system to be calibrated. The calibration frame has at least three calibration frame reference features. The positions of the support points and of the calibration frame reference features in a shared coordinate system are known.

System and method for calibrating reference system for vehicle measurement

A calibration frame for calibrating a reference system for vehicle measurement has setting elements, which enable a precise spatial orientation of the calibration frame, and multiple defined points of support, which are designed to accommodate a reference system carrier. In one specific embodiment, the points of support are designed in such a way that the reference system carrier is situatable on the points of support in at least two different orientations. In a second specific embodiment, a leveling element is provided which indicates the spatial orientation of the calibration frame in relation to the earth's gravitation field.

Method and device for calibrating a reference system for vehicle measurement

A method for calibrating a vehicle surroundings sensor () includes the steps of attaching at least one target pair () to the rear wheels () of a motor vehicle (); recording the target pair () using at least one measuring unit () and determining the vehicle axis () from the recording; placing a target () in a known position relative to a vehicle surroundings sensor adjustment or calibration element (); fastening at least one measuring unit () by means of fastening adapters () to a running rail (); recording the target () placed on the vehicle surroundings sensor adjustment and determining the angular position of the vehicle surroundings sensor adjustment or calibration element () relative to the vehicle axis (); aligning the vehicle surroundings sensor adjustment or calibration element () relative to the vehicle axis (); and adjusting the vehicle surroundings sensor () relative to the vehicle axis ().

Method for adjusting or calibrating a vehicle surrounding sensor, and a vehicle surrounding sensor adjustment or calibration system

A method and a device are provided for the optical axle alignment of wheels of a motor vehicle. At the wheels that are to be aligned, targets are mounted, having optically recordable marks, the targets being recordable by measuring units that have stereo camera devices. In a referencing process, using a referencing device that is integrated into the measuring units, a measuring position reference system is established for the measuring units. In a calibration process, in which a local 3D coordinate system is established using at least three marks of the target, the determination of a reference plane is carried out, using a significant mark of the target. Finally, using the reference plane, a vehicle longitudinal center plane is ascertained, while taking into account the measuring location reference system. In a subsequent measuring process, an image is recorded of at least three indeterminate marks taken during the calibration process, and their spatial position is ascertained in the local 3D coordinate system by the evaluation unit.
