CALIBRATION DEVICE, METHOD AND SYSTEM FOR A CONTAINER CRANE

摘要

A device, method and system for automatic calibration of a container crane, said container crane being controlled by a system comprising a first sensor (LPS) and/or a second sensor (TPS). In one aspect the invention discloses a calibration rig (1) arranged in a fixed position and comprising a plurality of markers, each arranged at a known and fixed position and distance relative to one another. The markers may comprise a first marker with a first visual appearance, or active marker (5) and/or a second marker with a second visual appearance, or passive marker (6). The active marker is preferably a illumination source, such as an IR source. A method for calibrating a container crane using the calibration device and a container control system comprising the calibration device and one or more computer programs are also described.
