Measuring confidence
LiveHigh confidence means two independent signals agree.
The reading service maps the printed fields of the registration document, including engine number, colour, fuel type, seat count, weights and usage purpose. The panel form uses only the ones a vehicle record needs. A format rule is a hard signal: a value that breaks it is wrong however sure the model is. Model confidence is a softer signal, and its threshold is set from measurement. The label is a measurement; a person gives the approval.
- A chassis number must have the correct length and contain no I, O or Q.
- Plates must match the Turkish plate format, and the document serial must follow its own letter and digit pattern.
- Identity and tax numbers must pass their checksums, and dates must be real calendar dates.
- In tests on real registrations, the QR code corrected serial letters that the text reader had returned wrongly with high confidence.
- The model is a text-recognition model fine-tuned on Turkish vehicle registrations. It replaced an earlier general-purpose attempt.
