3. Configurate the height of license plate character and the accepted
confidence level.
Through setting maximum and minimum character height that can
help LPR engine to limit on reading the height of license plate
character that you set, and ignore unwanted information. Usually
the character height of license plate around 25 to 80 pixels can be
recognized.
Minimum confidence (tpc) is minimum reliability in the reading of a
license plate to consider it valid. Reliability is a parameter returned
by the engine for recognizing license plates (value of 1-100, where
100 is the most reliable).
We recommend to keep using default character height settings (25
and 80 pixels) and if needed you can try to adjust confidence level
first.
