System and method of calibrating an optical sensor mounted on board of a vehicle

A method of calibrating a vehicle optical sensor, comprising:

• positioning a vehicle in a test station and proximate a projection surface, the vehicle having an optical sensor, the projection surface in view of the optical sensor;
• determining a position of the optical sensor with respect to the projection surface using a control unit that is external to the vehicle;
• selecting an image to be displayed;
• displaying the image from the projection surface;
• adapting the image displayed from the projection surface to dimensions of the projection surface, using the control unit, based on a size of the projection surface and the position of the optical sensor;
• spatially adjusting the projection surface with respect to the position of the optical sensor;
• and
• calibrating the optical sensor by adjusting a position of an optical axis of the optical sensor based on the image.

A calibration system for calibrating an optical sensor in a vehicle, comprising:

• a projection surface;
• a test station for a 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 to be displayed;
• display the image on the projection surface;
• adapt the image displayed on the projection screen to dimensions of the projection screen based on the size of the projection surface and the position of the optical sensor;
• spatially adjust the projection surface with respect to the position of the optical sensor;
• and
• calibrate the optical sensor by adjusting a position of an optical axis of the optical sensor based on the image.

A control unit for calibrating an optical sensor in a vehicle, the control unit positionable external to the vehicle, the control unit configured to:

• determine a position of the optical sensor that is with respect to a projection surface that is external to the vehicle;
• select an image to be displayed;
• display the image from the projection surface;
• adapt the image displayed from the projection screen to dimensions of the projection screen based on the size of the projection surface and the position of the optical sensor;
• spatially adjust the projection surface with respect to the position of the optical sensor;
• and
• calibrate the optical sensor by adjusting a position of an optical axis of the optical sensor based on the image.
