This technique enhances the submarines' reliability by providing them with diverse sources of data that can compensate for each other's weaknesses. For example, combining sonar data with camera images helps submarines cope with low visibility underwater and detect objects that may be invisible to cameras alone. It's like giving submarines a more complete picture of their environment, helping them navigate safely and effectively.

Combining data from different sensor types seems to be mandatory in a complicated and changing environment as the one any submarine travels through. Cameras may provide color information and ability to determine the nature of close-by objects or animals, but sonar will allow the submarine to derive the correct path.

Multi-modal fusion is pivotal in enhancing the perception capabilities of autonomous submarines. By leveraging diverse sensor inputs, these systems can create a more comprehensive understanding of the underwater environment. This is particularly crucial in scenarios where one sensor type might be impaired due to environmental factors.
