# How can a ship operator or yard use computer vision to review hull video from divers or underwater drones?

Train a model on the operator own hull video and photos so it can mark frames that likely show heavy fouling, coating damage, corrosion, dents, damaged anodes or blocked sea chest grates. Each mark carries the time in the video and, where the footage has it, the position on the hull, so a qualified surveyor or engineer can watch the clip and decide what it means. The model only helps people find the frames worth a look; it never decides seaworthiness, class or repair needs, and all diving and drone work follows the existing safety rules.

## What this means in practice

- Collect past hull videos and photos that surveyors have already reviewed, across different water clarity and lighting
- Label the conditions the inspection program tracks, plus clean hull sections for comparison
- Run new footage through the model and list flagged frames by time and hull area
- Have a qualified surveyor or engineer review each flagged frame and record the finding
- Add reviewed frames back into training so the model fits the fleet, coatings and local waters

## How Lid Vizion approaches it

We start with the business decision and operating context, define ownership and measurable milestones, then use configuration, integrations, automation, or custom software only where each earns its place.
