Method and apparatus for calibrating a camera system

A method of calibrating a camera system (220), comprising: - arranging (102) of the camera system in a calibration position; - projecting (104) a calibration plate (331) in a plane in front of an image sensor of the camera system; and - calibrating (106) of the camera system based on a predetermined algorithm using the projected into the plane calibration board, characterized, in that the calibration plate (331) is projected to an intended Verbauposition of the camera system (220) is adjusted, wherein it is a projected installation position of the camera system (220) in a vehicle, during calibration (106) of the camera system (220) the projected installation position of the camera system (220) is taken into account in the vehicle.
