Overview
OCR2-PAK is an enhancement to the CVIM2 that provides Optical Character
Recognition (OCR) and Optical Character Verification (OCV). After
OCR2-PAK is installed, OCR is listed as an option in the Tool Types panel.
An OCR Tool can be used in two ways:
•
OCR mode reads characters within the tool’s processing window. It does
not use a match string to verify what text is present.
•
OCV mode reads characters within the tool’s processing window, and
compares the text read to a match string entered by the user.
Both OCR and OCV have standard and strict operating modes. These modes
determine how the OCR2 package handles printed characters that correlate
with two or more different taught characters.
