License Plate Detection (LPR) for .NET MAUI recognition processor
Recognizes license plates of many European countries together with vehicle types.
Supported vehicle types:
- Car
- Motorbike
- Tractor
- Truck
Supported countries:
A, B, BG, CH, CZ, D, DK, E, EST, F, FIN, FL, GB, GR, H, HR, I, IRL, L, LT, LV, NL, P, PL, RO, S, SK, SLO
Features
- New multi-model algorithm for improved recognition accuracy (>98%)
- Different model qualities selectable for performance optimization and better adaptation to the used hardware platform
- Vehicle detection can be switched off for higher performance
- Models can be integrated directly into your deployment or automatically downloaded at runtime
- Background download of models before recognition is supported (recognition fails if models are missing)
Recognition Modes (new in 2.1.0)
The detection can be configured in different modes depending on application requirements:
- Country-based plate → then vehicle type (vehicle type is detected only if a plate was recognized).
- Country-based plate only (no vehicle type detection).
- Vehicle type only.
- Vehicle type first → then country-based plate (plate search only inside detected vehicles).
- "No country" plate → then vehicle type (plate detection without country validation).
- "No country" plate only (no vehicle type detection).
- Vehicle type first → then "no country" plate (plate search only inside detected vehicles).
The new "No Country" plate detection allows reliable recognition of most license plates, even if the country is not explicitly trained.
Limitation: No country validation of recognized plates.
Model Download
The following models can only be used together with the CapCognition license plate detection library.
They are not permitted for use in other libraries.
Platform Support
- iOS (minimum target framework: iOS 13)
- Android (minimum target framework: Android 9)
Trial Version
This library can be used as a trial version.
- The trial version is limited to a certain number of recognitions per application start.
- After the limit is reached, the application must be restarted.
- The trial version is intended for development and testing only, not for production use.
- For production use, a license must be purchased.
