Abstract:
1. A method for adjusting or calibrating a vehicle surroundings sensor, comprising the following steps: fastening at least one measuring unit by means of fastening adapters to a running rail in a position between a front wheel and a rear wheel of the vehicle, wherein the at least one measuring unit includes at least two measuring cameras with reverse viewing direction, whereby at least one measuring camera has a forward viewing direction and at least one camera has a backward viewing direction, wherein the at least one measuring unit includes cross referencing for determining a position of one of the at least one measuring unit relative to a position of another one of the at least one measuring unit, wherein said cross referencing comprises cross-reference cameras that are directed in a transverse direction of the vehicle and detect optical features that are oppositely disposed on the at least one measuring unit; attaching at least one target pair to rear wheels of a motor vehicle; recording the target pair using said at least one measuring unit and determining the vehicle axis from the recording; placing at least one target in a known position relative to a vehicle surroundings sensor adjustment or calibration element; recording the target placed on the vehicle surroundings sensor adjustment or calibration element using the at least one measuring unit 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 or calibrating the vehicle surroundings sensor relative to the vehicle axis.
