The markers may include a first marker with a first visual appearance, or active marker and/or a second marker with a second visual appearance, or passive marker. The active marker is preferably an illumination source, such as an IR source. A method for calibrating a container crane using the calibration device and a container control system including the calibration device and one or more computer programs are also described.
