4-4 Reading and Verifying Character Strings
Character String Recognition
Character recognition is used to read characters in input images as character information based on font
information that is registered in the Sensor in advance. The characters that were read can be output to an
external device. You can also verify the character string that was read to see if it matches a character string that
was registered in advance or the read result from a Bar Code, 2D-code, or 2D-code (DPM) inspection item that
was executed before the current inspection item.
