Underwater Camera That Sees 2-3x Further in Murky Water With 3D Video

environmentTestedTRL 5

Imagine trying to take photos underwater but the water is so murky you can barely see a metre ahead — that's what divers and underwater robots deal with every day. UTOFIA built a special camera system that uses laser pulses and clever timing to cut through the murk, seeing 2 to 3 times further than normal underwater cameras while also capturing everything in 3D video. Think of it like giving underwater vehicles a pair of superhero eyes that work in the worst visibility conditions. It fills the gap between regular video cameras (clear but short range) and sonar (long range but blurry).

The business problem

What needed solving

Underwater operations in ports, fish farms, and offshore sites are severely limited by poor visibility — conventional cameras lose effectiveness in turbid water, while sonar gives range but not image detail. Companies end up choosing between expensive, blurry sonar surveys or short-range video that misses most of the picture. This gap costs money through incomplete inspections, inaccurate stock counts, and missed hazards.

The solution

What was built

A compact range-gated underwater imaging system that extends visibility 2-3x beyond conventional cameras while providing real-time 3D video. The consortium delivered a functional prototype with test report, plus 8 total deliverables covering system integration and demonstration.

Business applications

Who can put this to work

Aquaculture & Fisheries

SME

Target: Fish farming companies and fisheries stock assessment firms

If you are an aquaculture operator struggling to monitor fish stocks in turbid coastal pens — this project developed a compact underwater imaging system that sees 2 to 3 times further than conventional cameras while delivering real-time 3D video. That means accurate biomass estimation and health monitoring without pulling nets or relying on imprecise sonar counts. The system was built to handle exactly the low-visibility conditions common in fish farm enclosures.

Port & Harbour Security

enterprise

Target: Port authorities and maritime security contractors

If you are a port authority dealing with underwater threat detection and litter accumulation in murky harbour waters — this project built a range-gated imaging system that extends visibility 2 to 3 times beyond standard underwater cameras. It provides video-rate 3D data, letting security teams inspect hulls, pilings, and harbour floors faster and more reliably. The system was demonstrated as a functional prototype tested across 7 countries.

Offshore & Marine Survey

mid-size

Target: Seabed mapping and offshore inspection companies

If you are a marine survey company limited by poor underwater visibility during seabed mapping or infrastructure inspection — this project developed a cost-effective imaging system that triples the working range of conventional video while adding 3D depth information. Instead of choosing between expensive sonar surveys or limited-range video, you get high-resolution 3D video at ranges previously only achievable by sonar. The prototype was built and functionally tested by a consortium of 8 partners.

Frequently asked

Quick answers

What would a system like this cost compared to current solutions?

Based on available project data, UTOFIA was designed to be 'compact and cost-effective' compared to existing underwater imaging and sonar systems. The project received EUR 5,716,971 in EU funding across 8 partners to develop the technology. Specific unit pricing is not disclosed in the project data.

Can this scale to industrial deployment for large-area surveys?

The system was designed to provide video-rate 3D imaging, which means it can capture data continuously during underwater operations rather than frame-by-frame. With a demonstrated imaging range extension of 2 to 3 times over conventional systems, it covers significantly more area per dive or ROV deployment. The prototype was functionally tested but commercial-scale production details are not in the project data.

What is the IP situation — can we license this technology?

The project was coordinated by SINTEF AS in Norway, a major research organization. With 3 industry partners and 2 SMEs in the consortium, IP arrangements likely exist between partners. Contact the coordinator for licensing terms and technology access.

How does this compare to existing sonar and camera systems?

UTOFIA fills the gap between short-range, high-resolution conventional video and long-range, low-resolution sonar. It extends imaging range by a factor of 2 to 3 over conventional cameras while maintaining video-rate 3D output. This means you get sonar-like range with camera-like image quality.

What specific applications has this been validated for?

The project targeted four application domains: marine life monitoring, harbour and ocean litter detection, fisheries and aquaculture stock assessment, and seabed mapping. A functional prototype was built and tested, confirmed by the deliverable 'System integration — prototype with functional test report'.

Is this ready to deploy or still in research phase?

A working prototype was built and functionally tested during the project period (2015-2018). The project produced 8 deliverables including a demonstrated prototype. However, there is no evidence of commercial deployment, so the technology likely needs further engineering for market-ready products.

Consortium

Who built it

The UTOFIA consortium brings together 8 partners from 7 countries (DE, DK, ES, FR, IT, NO, UK), coordinated by SINTEF AS — one of Europe's largest independent research organizations based in Norway. The mix of 4 research institutes and 3 industry partners (including 2 SMEs) at a 38% industry ratio shows a research-heavy team with meaningful commercial input. The broad geographic spread across major maritime nations suggests the technology was tested against diverse underwater conditions. For a business buyer, SINTEF's involvement adds credibility, while the SME participation indicates the technology was designed with commercial viability in mind.
