How you scan matters as much as what you scan.

This EngD project will develop autonomous underwater inspection systems for assessing the structural integrity of submerged assets such as submarines, ship hulls, offshore structures and marine infrastructure using non-destructive testing (NDT).

While underwater unmanned vehicles (UUVs) can increasingly map and survey assets, reliable detection of cracks, corrosion and other hidden defects still depends on high-quality sensing under difficult, highly variable conditions. The vehicle's control history partly determines the information content of the NDT signal, so structural inference must be conditioned on sensing actions, contact state and motion uncertainty.

By combining the control of the system with the structural assessment, the project creates control-aware active perception methods that allow an autonomous platform to decide not only what to inspect, but also how to position itself to obtain the most informative measurements. This results in safer maritime operations, reduced inspection cost and improved resilience of critical underwater infrastructure.
