🌊 When the seabed looks featureless, how do you ensure you collect the right data to build a reliable 3D model?
Last week, we showed how Tritonia Scientific’s modified ROV followed an autopiloted survey pattern over a rocky reef with approximately 7 metres of elevation change.
This second video highlights a different challenge from the same environmental survey at an active fish farm on Scotland’s west coast: a largely featureless seabed.
Here, autopiloting was essential to maintaining a precise, repeatable survey pattern and collecting the overlapping imagery required for reliable 3D photogrammetric model generation.
As with the rocky reef survey, the ROV operated at a controlled speed of 0.25 m/s, maintaining a target altitude of 1 metre above the seabed and, importantly, horizontal positioning so accurate as to enable precise parallel survey lines that are fundamental to achieving 100% coverage.
🎥 The animated ROV follows the actual flight pattern flown during the survey, and the seabed shown is the actual 3D model generated from the collected imagery.
Across eight plots and more than 3,100 m² of seabed, automated missions enabled systematic, planned coverage, helping minimise gaps and provide the consistent image overlap needed for continuous digital models. The other survey areas presented seabed conditions between the two contrasting extremes shown in our videos.
The resulting models are hosted on Hydrophis, Tritonia’s underwater data management platform, where users can explore and measure the seabed directly.
This work is part of four years of R&D, supported by HIE, the Sustainable Aquaculture Innovation Cluster (SAIC), CivTech, the UK Seafood Innovation Fund (SIF), FHF and Innovate UK, alongside the practical support and collaboration of salmon producers.
Different seabed conditions. The same principle: systematic surveying and consistent data collection are fundamental to reliable 3D modelling.
