License Plate Recognition Service

The ALPR (Automatic License Plate Recognition) Engine Setting allows users to choose between two OCR (Optical Character Recognition) engines for license plate detection and recognition tasks

To access the service, go to APLR Service in the Setting page.

ALPR Engine Options​

  • ANS OCR Detector: Optimized for high-accuracy recognition of Vietnamese license plates.
  • Built-in OCR Detector: A more general-purpose engine suitable for international or non-standard plates.

Setting Parameters​

  • Detector Threshold: Adjusts the confidence level for plate detection. A lower value may detect more plates but may include false positives.
  • OCR Threshold: Sets the confidence level required for the OCR engine to confirm a recognized character. Higher values ensure greater accuracy but might miss unclear plates.
