Setting Up the Standard OCR Tool

The flow of basic setting operations for the Standard OCR tool is as follows.

 

  1. Add an OCR Tool to the image area.
  2. Change the operating mode from [IntelliText OCR] to [Standard OCR].
  3. Adjust the region of interest (ROI) to cover the area where you expect the read object to move. For best results, make this ROI as large as possible.
  4. Select the font library to use for reading. The read results are displayed graphically.
  5. If you have trouble reading characters, add the target font to your font library. See the Add/Remove Fonts section.
  6. If character extraction is not successful, adjust the setting parameters for character selection and Image Pre-Processing etc. See the Standard OCR Tool Parameters section for details.
  7. If you want to verify the read result, register the Match String. See the OCR Tool Match String section.

 


Note: The OCR Tool can be enabled for ROI rotation by clicking the rotation icon at the upper left of the parameters view.

          


 


Precautions for Correct Use: When switching between Standard OCR and IntelliText OCR, the links between tool outputs and GDS tags are lost. This is because the underlying components that make up the OCR Tool are completely removed and then recreated whenever you change the tool’s capability.
