Review of Visual Control Technology for Undersea Vehicles

Visual control is a control method that utilizes visual information for environmental and self-state awareness. In this paper, this technology was applied to control undersea vehicles, and relevant research progress, challenges, and trends in different application scenarios were analyzed. The current development and task scenarios of visual control technology for undersea vehicles were first introduced, mainly focusing on underwater image enhancement, target recognition, and pose estimation technologies. The current development of visual control technology for undersea vehicles was then summarized and analyzed based on three task scenarios: underwater visual dynamic positioning and target tracking, undersea vehicle docking, and underwater operational tasks such as target grasping. Finally, the challenges and development trends of visual control technology for undersea vehicles were outlined.
