Information from the China National Intellectual Property Administration shows that ABB Switzerland Ltd. has filed a patent titled “Method, Controller, Positioning Device and Computer Program for Determining the Position of a Container in a Container Slot of a Container Ship,” with publication number CN121225456A, filed in June 2025.

The patent describes a machine learning and computer vision-based method for determining the precise position of containers on container ships, aiming to improve automation and accuracy in port and vessel cargo handling operations.

According to the filing, the method involves receiving image data from at least one camera installed on the structure of a crane. The crane structure extends at least partially above the container slot area on the vessel. The captured image data includes a first image and at least a second image, each showing the region of the container slot where the container is placed.

A machine learning algorithm then processes the multi-view image data to determine the exact position of the container within the designated slot on the ship.

By combining visual sensing with AI-based analysis, the technology is designed to enhance positioning accuracy, improve operational efficiency, and support the development of smarter and more automated port logistics systems.
