Claim One:
1. An apparatus for adjusting and/or calibrating a multi-camera module having a plurality of cameras, the apparatus comprising: an optical arrangement for creating first virtual test structures at an infinite distance and second test structures at a finite distance, wherein the optical arrangement comprises at least one collimator, which is configured to create the first virtual test structures at the infinite distance by imaging of a first graticule, and wherein the test structures are simultaneously detectable with the cameras of the multi-camera module; a processing unit for evaluating a picture of the first and second test structures captured with the multi-camera module, wherein the processing unit is configured to calculate an alignment of the cameras of the multi-camera module relative to each other from the captured picture, wherein the picture captured with the multi-camera module comprises an individual image per camera, and wherein each individual image displays the first and/or the second test structures and the processing unit is further configured to calculate an alignment of the cameras relative to each other by comparing positions of the test structures in an individual image of a camera with positions of the corresponding test structures in an individual image of a further camera and calculating deviations; and an adjusting and/or calibrating unit, which is configured to align said cameras relative to each other based on data relating to the alignment of the cameras of the multi-camera module and thereby adjust and/or calibrate the multi-camera module.
