[0002] In the fields of marine engineering, water environment survey, large-scale water conservancy project facility monitoring, etc., underwater mobile platform monitoring systems and methods play a key role:

[0003] The criticality of underwater mobile platform positioning: Marine engineering and water environment surveys often require complex tasks to be performed underwater, such as installing and maintaining submarine cables, pipelines, sensors, monitoring equipment, etc. Accurate underwater platform positioning is a key prerequisite for performing these tasks. In addition, large-scale water conservancy engineering facilities, such as dams, hydropower stations, and port facilities, also require maintenance and monitoring of underwater structures, which also requires accurate underwater platform positioning.

[0004] Underwater environment challenges: The underwater environment is full of challenges, including high water pressure, salinity changes, ocean currents, corrosion, etc. These factors place strict demands on the long-term reliability of underwater equipment and the accuracy of positioning systems. Especially in the monitoring of large-scale water conservancy engineering facilities, these environmental factors may cause equipment damage or inaccurate monitoring data.

[0005] The need for precision underwater installation: In marine and hydraulic engineering, equipment and structures need to be precisely installed to ensure their normal operation. This includes ensuring that components such as pipes and cables are correctly connected and positioned, and ensuring that underwater monitoring equipment can accurately record data. Precision installation is essential to prevent leaks, maintain safety, and ensure the long-term reliability of engineering facilities.

[0006] However, the existing technologies have some deficiencies in these areas:

[0007] Inaccurate positioning of underwater mobile platforms: Traditional positioning methods for underwater mobile platforms are usually limited by the unavailability of GPS signals, resulting in reduced positioning accuracy of underwater targets. This poses a challenge for tasks that require high-precision positioning, such as seabed resource exploration and underwater building monitoring.

[0008] Complexity of underwater environment: The underwater environment is complex and full of various obstacles, such as reefs, seaweed, sunken ships, etc. It is difficult for existing systems to effectively plan paths to avoid these obstacles, which may cause equipment damage or mission failure.

[0009] Difficulty in underwater target recognition and classification: In underwater environments, the recognition and classification of underwater targets is a challenging task. Traditional methods often rely on manual intervention or use limited sensors, making it difficult to achieve real-time target recognition and classification.

[0010] Long-term monitoring and tracking challenges: Some applications require long-term monitoring and tracking of underwater targets, such as ecosystem research or large-scale water conservancy project facility monitoring. The power management and data logging capabilities of existing systems may not be sufficient to support long-term operation.
