Marine Technology

Autonomous underwater 2D and 3D mapping.

One vehicle, one stereo pair — no pilots, no acoustic array. The mission flies itself and returns a metric map of whatever is down there: reefs, shipwrecks, pipelines, underwater infrastructure.

Mission views

Seen from the mission.

Two views of the same run — the vehicle over the survey area, and the mapping target from above.

Mission console

The whole stack. One console.

Simulator, autopilot and the mission itself — started, watched and stopped from one screen. What you see is what runs the vehicle.

One system, many missions

Built for the reef. Ready for everything else.

Coral restoration is our flagship application — the same vehicle, sensors and pipeline map any underwater subject at survey grade.

01

Coral restoration

Survey-grade baselines to prove what is recovering — and what needs replanting.

02

Shipwreck mapping

Full 2D and 3D records of wrecks for research, heritage and safety.

03

Subsea pipelines & cables

Repeatable inspection runs without diving teams or acoustic arrays.

04

Underwater infrastructure

Monitoring for ports, offshore assets and critical undersea works.

The problem — coral first

We are losing reefs faster than we can map them.

Hard coral cover fell from 30.2 % in 1980–2009 to 27.3 % in 2020–2024. In 2024 it dropped 8.9 % in a single year — the largest one-year loss on record. Restoration is decades behind the loss, and most of it is still done by hand.

The bottleneck is not intent — it is evidence. Median restoration monitoring lasts about 12 months, far shorter than coral maturity. Without repeatable, metre-scale mapping, nobody can prove which sites are recovering — and restoration budgets keep paying for guesswork.

How it works

From reef to orthomosaic.

01 · Capture

Stereo 20 Hz + IMU

No acoustic array, no topside gear, no extra vessel — the entire survey kit rides with the vehicle.

02 · Localise

Onboard localisation

The vehicle's own sensing turns motion into a 20 Hz pose stream — under 0.5 % error in simulation, without survey-grade gear.
03 · Reconstruct

2D orthomosaic + 3D model

Full-resolution stills at each waypoint become a 2D orthomosaic and a 3D model. One dive, two deliverables: metrics for science, maps for decisions.

Outputs

Maps in 2D and 3D.

Every mission pays twice: a live pose stream for navigation, and a permanent record of the seabed — delivered in 2D and 3D.

Why this approach

Survey-grade accuracy, without survey-grade hardware.

MethodHardware costNotes
Acoustic USBL / SBL~ US$10,5202–4 Hz update rate; needs a topside transducer and vessel logistics.
Doppler Velocity Log (DVL)~ US$8,710Precise, heavy, bulky — and about 31× the cost of the stereo kit (Liu et al. 2024).
DeepVertex (DVX) Stereo Camera~ US$280Passive, light, and a fraction of the cost — needs camera–IMU calibration and seabed texture.

Status

Simulation done. Pool test next.

The full pipeline is validated in simulation. The next milestone is a controlled pool run — 10 × 10 m area, 6 m depth — and a pressure-chamber check before open water.
