Judgement By Recognition Rate - Panasonic IMAGECHECKER PV230 Manual

2.6.6 Judgement by recognition rate

It judges whether or not the recognition rate of the character judged as
OK by the specified character string or the calendar date is higher
than the specified minimum value. If the rate is not higher than the
specified minimum value, the character is judged as NG, and "?" is
output for the judged character.
This is a function to simply inspect the quality using the recognition
rate calculated with correlation or subtraction after character
recognition.
The following methods are available for setting the minimum recognition rate; Set the same minimum value
for all character strings (Not perform individual judgement), set per recognized character (Per judgement
character) and set per dictionary label.
•
No individual judgement:
Judges all characters of character strings using the same
criterion for recognition rate.
•
Per Judgement Char.:
Specify the minimum recognition rate per recognized
character number. It is used to set different criteria for the
recognition rate according to the position in the character
string even for the same character (label).
•
Per Dictionary Label:
Specify the minimum recognition rate per dictionary label.
The criteria for the recognition rate are the same for the
same character (label) regardless of the position.
When "Recognition rate method" has been set to an item other than "No", the error code 180 is displayed if
executing an inspection after reading dictionary (learning data only), and the Err signal turns on. For the
details of reading dictionary data (learning data only), refer to 4.4 Reading SD Dictionary with External
Device.
The same criterion regardless of
character numbers or dictionary
labels.
Although the characters are the
same, criteria differ according to
recognized positions.
When the characters (labels) are
the same, the criteria are the
same.
