License Plate

New in version 3.17.

The License Plate Module can be used to scan license plates of different sizes and from different countries.

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

This means that the license plate does not have to be exactly in the cutout, and angles of up to ~40° vertically and ~50° horizontally are possible for scanning.

This section describes the parameters in detail.
If you are looking for a How-To on loading the License Plate Module on your platform, please refer to the following sections:
