Abstract
A method for loading a container on a landing target on a land vehicle using a container crane including a trolley and a spreader for holding and lifting the container. The method is performed in a container crane control system and includes the steps of: obtaining two-dimensional images of the landing target from a first pair of cameras arranged on the spreader; performing feature extraction based on the two-dimensional images to identify key features of the landing target; generating a point cloud based on the feature extraction, wherein each point in the point cloud contains coordinates in three dimensions; and controlling movement of the container to the landing target based on the point cloud and the identified key features of the landing target.

A method for loading a container on a landing target on a land vehicle using a container crane including a trolley and a spreader for holding and lifting the container, the method being performed in a container crane control system and comprising the steps of:
- obtaining two-dimensional images of the landing target from a first pair of cameras arranged on the spreader;
- performing feature extraction based on the two-dimensional images to identify key features of the landing target;
- generating a point cloud based on the feature extraction, wherein each point in the point cloud contains coordinates in three dimensions;
- and
- controlling movement of the container to the landing target based on the point cloud and the identified key features of the landing target.
A container crane control system for loading a container on a landing target on a land vehicle using a container crane including a trolley and a spreader for holding and lifting the container, the container crane control system comprising:
- a processor);
- and
- a memory storing instructions that, when executed by the processor, cause the container crane control system to:
- obtain two-dimensional images of the landing target from a first pair of cameras arranged on the spreader;
- perform feature extraction based on the two-dimensional images to identify key features of the landing target;
- generate a point cloud based on the feature extraction, wherein each point in the point cloud contains coordinates in three dimensions;
- and
- control movement of the container to the landing target based on the point cloud and the identified key features of the landing target.
A computer program for loading a container on a landing target on a land vehicle using a container crane including a trolley and a spreader for holding and lifting the container, the computer program comprising computer program code which, when run on a container crane control system causes the container crane control system to:
- obtain two-dimensional images of the landing target from a first pair of cameras arranged on the spreader;
- perform feature extraction based on the two-dimensional images to identify key features of the landing target;
- generate a point cloud based on the feature extraction, wherein each point in the point cloud contains coordinates in three dimensions;
- and
- control movement of the container to the landing target based on the point cloud and the identified key features of the landing target.
A computer program product comprising a computer program including a computer program which, when run on a container crane control system, causes the container crane control system to:
- obtain two-dimensional images of the landing target from a first pair of cameras arranged on the spreader;
- perform feature extraction based on the two-dimensional images to identify key features of the landing target;
- generate a point cloud based on the feature extraction, wherein each point in the point cloud contains coordinates in three dimensions;
- control movement of the container to the landing target based on the point cloud and the identified key features of the landing target;
- and
- a computer readable means on which the computer program is stored.
