The patent US12054363B2 describes an innovative crane system designed for onshore, offshore, and ship applications, utilizing optical targets and advanced tracking technology. The system includes one or more optical targets placed on objects, a target tracking device mounted on the crane or vessel, and a controller that processes data from the tracking device. The tracking device features a camera that captures images of the optical targets, enabling the controller to calculate relative distances and motions between the targets and the crane or vessel. This functionality allows for precise control of the crane's hook or the vessel's navigation towards the targets, enhancing operational efficiency and safety.

Additionally, the system incorporates RFID technology, with readers and tags that facilitate communication between the controller and the optical targets. The tracking device is designed to scan a specified angular range to ensure the targets remain within its field of view, providing alerts if they move outside this range. The optical targets can have distinct tag patterns, allowing for differentiation between multiple targets on various objects. This patent outlines a comprehensive approach to improving crane and vessel operations through advanced tracking and control mechanisms, which could significantly impact industries reliant on heavy lifting and precise positioning.
