Researchers have developed a new method for autonomous underwater vehicles (AUVs) to search for and track subsea cables, which are crucial for global communications but vulnerable to damage. The system uses uncertain prior cable route maps and a graph-based optimization approach that continuously updates the cable's route based on visual observations. Physics-based catenary models constrain the search space, improving efficiency, while a real-time semi-supervised classifier detects the cable. This method was successfully demonstrated in field trials, enabling the AUV to locate a cable despite initial map errors and inspect a significant portion of it, even recovering from tracking loss.
