arXiv:2605.24195v1 Announce Type: cross Abstract: Sonar is often the only modality suitable for high-resolution imaging underwater due to light attenuation and turbidity. Forward-looking imaging sonar provides measurements over range and horizontal angle but collapses vertical structure into a flat image, creating ambiguities that make 3D recovery challenging. A common use case for imaging sonar is underwater terrain mapping (bathymetry), yet current methods require many views, expensive multi-sensor setups, or significant training data, which limits use and adaptability to new environments.

Advances in AI, specifically differentiable rendering, are reaching a maturity that allows for novel applications in challenging sensing environments like underwater imaging.
This development could significantly enhance autonomous underwater vehicle capabilities and remote sensing, critical for defence, resource exploration, and environmental monitoring.
The ability to perform high-resolution 3D seafloor recovery from single-view sonar data reduces the cost and complexity of underwater mapping, making it more accessible and efficient.
