edented ef? ciency, accessibility, and reliability. ROVs serve as valuable tools for data collection, observation, and monitoring in underwater environments, signi? cantly en- hancing the accuracy and reliability of modeling processes.

They improve the quality and quantity of data available for modeling, fostering better understanding, analysis, and man- agement of underwater environments and structures.

Different imaging sensors on ROVs, including monocular and stereo cameras, sonar, and laser scanners, capture photo- grammetry data, enabling the creation of detailed digital twins and highly accurate maps in both 2D and 3D, even in turbid water conditions.
