  • Method and system for automatically landing containers on a landing target using a container crane
    Patent number: 9611126
    Abstract: A method for automatically landing a container on a landing target using a container crane is disclosed. The container crane includes a trolley and spreader for holding and lifting the container and a crane control system for controlling movements of the container crane. A distance from the container to the landing target is measured and the container is moved towards the landing target dependent on the measured distance. A plurality of images of the landing target is made using at least one camera mounted on the spreader. The images are processed to identify one or more landing features in the images of the landing target. Distances from the container to the landing target are calculated based on a measurement of distance between the container and the landing features in the images.
