ROV-INTEGRATED 3D CAPTURESubsea reality.
Delivered in 3D.
MariSoft combines purpose-built underwater stereo vision, in-housing calibration and structured image capture to produce photorealistic, true-scale 3D records of subsea assets.
Explore the workflow ↓
Inspection geometry reconstructed for direct subsea pipeline measurement.
/ 01 — DIGITAL ASSET RECORD
Capture once.
Inspect repeatedly.
Dense 3D reconstruction turns underwater imagery into an inspection surface that can be revisited onshore, viewed from new angles and used to support dimensional assessment without returning to the asset.
- Photorealistic geometry
- True-scale spatial context
- Remote visual review
- Measurement-ready outputs
Subsea structural geometry reconstructed from overlapping inspection imagery.
/ 02 — FROM CAMERA TO MODEL
- 01Capture
Acquire overlapping stereo and RGB imagery from an ROV-mounted, calibrated camera assembly.
- 02Calibrate
Apply housing-specific intrinsics, distortion coefficients and rigid camera transforms.
- 03Reconstruct
Resolve aligned imagery into dense, colour-rich geometry and true-scale asset context.
- 04Inspect
Review structures, components and areas of interest remotely from multiple viewpoints.
- 05Measure
Use the reconstructed model for dimensional assessment, comparison and survey deliverables.
/ 03 — UNDERWATER CALIBRATION
Calibrated as one optical system.
Water and housing viewports change effective projection geometry. MariSoft therefore calibrates the cameras inside their final operational housing, so the exported model captures the lenses, viewports, water interface and mechanical alignment together.
Submerge + stabilise
Fully wet the optical faces, clear trapped bubbles and stabilise the assembly in water.
Acquire target views
Capture a calibrated target across depth, tilt and the complete image area.
Solve intrinsics
Estimate focal length, principal point and the distortion model for every camera view.
Solve transforms
Calculate the rigid rotation and translation between the coordinated camera views.
Validate + export
Check stereo alignment and known distances, then deliver the production camera model.
/ 04 — CAPTURE SYSTEMS
Two architectures.
One coordinated workflow.
Select an integrated RGB-D configuration or a dual-GigE stereo assembly according to the vehicle, image pipeline and inspection objective.

/ 05 — ROV INTEGRATION
Designed around the inspection spread.
The camera assembly integrates into ROV operations so geometry-rich imagery can be acquired alongside the inspection campaign. Final placement, interfaces and capture profile are configured around vehicle access, standoff and the asset being surveyed.
/ 06 — RECONSTRUCTION OUTPUTS
Geometry with the visual detail to support engineering review.
Dense geometry and colour preserved across pipework, valves and structural features.
Inspection-ready visual context for focused remote review.
True-scale reconstruction for spatial understanding and assessment.
/ 07 — APPLICATIONS
Built for subsea inspection, metrology and verification.
