How can a car wash or fleet wash bay use computer vision to check how clean vehicles come out?

Results are tagged with the time and wash package, so the site lead can see which brushes, nozzles or chemicals need attention when misses cluster. Blur faces through windows and blur plates before photos are stored. Staff review the flags, offer a rewash where needed and decide what to adjust.

# How can a car wash or fleet wash bay use computer vision to check how clean vehicles come out?

Cameras at the entry and the exit of the tunnel or bay take photos of each vehicle. A model trained on the operator own images marks spots that still look dirty, such as wheels, lower panels, rear windows and bug spots, and flags vehicles that come out wet or streaked. Comparing the entry and exit photos also keeps a simple record of how each vehicle looked before and after the wash, which helps staff answer questions about marks or damage. Results are tagged with the time and wash package, so the site lead can see which brushes, nozzles or chemicals need attention when misses cluster. Blur faces through windows and blur plates before photos are stored. Staff review the flags, offer a rewash where needed and decide what to adjust. The model does not replace equipment checks, staff walk-arounds or site rules, and people make every customer and maintenance call.

## What this means in practice

- Start with one tunnel or bay and both entry and exit cameras.
- Label photos from your own site for dirty spots, streaks and water left on.
- Blur faces and plates before photos are stored.
- Tag results with the time and wash package.
- Review clusters of misses to plan brush and nozzle checks.

## How Lid Vizion approaches it
