# How can a tunnel owner or engineering team use computer vision to review tunnel inspection images?

Cameras on an inspection vehicle or cart capture the tunnel lining in a steady sweep, and the model marks spots that may need a closer look, such as cracks, water leaks, wet patches, staining, spalling, loose or missing panels and damaged lights or signs. Each mark is saved with the image and its spot along the tunnel, so the team can compare against the last pass and see what is new or growing. A licensed engineer decides on every mark, and all required inspections and reports stay in place.

## What this means in practice

- Cameras and lights on an inspection vehicle, rail cart or trolley capture the full tunnel lining in a steady sweep, ideally on the same route and settings each time.
- The model is trained on the owner own tunnel images. It marks spots that may need a closer look, such as cracks, water leaks, wet patches and staining, spalling or exposed rebar, loose or missing panels or tiles, and damaged lights, signs or cable trays.
- Each mark is saved with the image, the station or distance along the tunnel and the date, so the team can line it up with the last pass and see what is new or growing.
- A licensed engineer or qualified inspector reviews every mark and decides what needs a hands-on look, a repair or just watching. The model never signs off on anything, and every required inspection, rating and report stays in place.
- Start with one tunnel or one stretch, compare the marks with what the inspectors find on their own walk-through, and blur any people or plates caught in the images.

## 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.
