11. A calibration system for calibrating an optical sensor in a vehicle, comprising:
a projection surface;
a test station for a vehicle such that, when the vehicle is positioned in the test station the projection surface is positioned in front of the vehicle, such that an optical sensor positioned in the vehicle has a view of the projection surface;
a control unit electrically connectable to the optical sensor and external to the vehicle, the control unit configured to:
determine a position of the optical sensor with respect to the projection surface;
select an image or video to be displayed;
display the image or video on the projection surface;
adapt the image or video displayed on the projection surface based on the size of the projection surface and the position of the optical sensor;
adjust a spatial position of the projection surface with respect to the position of the optical sensor based on the adapted image or video after displaying the adapted image or video; and
calibrate the optical sensor by adjusting a position of an optical axis of the optical sensor based on the image or video.
