The main properties of the license plate recognition pipeline are configured here.
Performance (both accuracy and speed) is higher if license plate recognition is limited to the part of
the image in which the vehicle is likely to be found. Vehicle Detection, Motion Detection or Virtual
Loop can provide such a frame, and users can define a manual frame also. Moreover, the
preliminary license data provided by the Preselection stage contains a license plate frame which can
be used at the ANPR stage.
In devices equipped with two image sensors, you can set up a secondary source functioning as
either Overview or ANPR. In ANPR mode, the system will attempt to find a license plate in the
secondary image.
