4.8.10
Minimum confidence
Each letter is recognized with a probability; it describes the similarity between its patterns,
as well as read letter. You can adjust the minimum characters confidence [%] to reject
letters with low match.
Figure 44 Minimum character recognition adjustments
Using this feature with font packages (document, industrial, etc.) containing multiple
fonts has lower confidence reliability, via comparison with multiple variants of the same
character. A decrease of confidence can also occur with similar characters such as "O"
and "0" (zero).
4.8.11
Reading type
OCR
OCR reads a text string and is capable to read poor quality and damaged text. Use the
OCR type, when you only need to read the text string sample.
OCV
The OCV (optical character verification) reads a text string, as well as comparing the
previously taught-in text with the text found on the object.
Use the OCV type, when the text string sample is already known, and to validate the
legibility of the text.
4.8.12
Expected text counter
Keep value
The expected text value will be the same.
Increment
After one iteration (trigger pulse) the expected text value will be increased by one (+1),
respectively.
Decrement
After one iteration (trigger pulse) the expected text value will be decreased by one (-1),
respectively.
