License Plate

Scan capability overview

Example License Plate

The License Plate Plugin can be used to scan license plates of different sizes and from different European countries and territories, the United States and Africa.

It includes license plate localization, perspective transformation and scanning of the license plate number - including possible country/territory information in an EU or similar badge.

License plates need to be fully visible inside the cutout and angles of up to ~40° vertically and ~50° horizontally are possible for scanning.
