7.5.5 Optical Character Recognition (OCR) Tool
Optical character recognition (OCR) is the electronic interpretation of printed text that has been captured by a Vision
Sensor. The OCR tool in the PresencePLUS software is used to train character patterns and their variations into the
Vision Sensor's font library so that the Vision Sensor can recognize character patterns on labels and packages. Each
character pattern is associated with a character ID so that the Sensor is able to identify character strings on a label or
package. For example, you might train different fonts for the letter (S or S) and use the keyboard to associate these
variations with the character ID "S".
Usage
The OCR Vision Sensor tool can be used:
• to ensure that the correct lot or date code is printed on a label or package.
• to ensure that the right labels are placed on the appropriate packages.
• with the Barcode tool to match strings and/or substrings with the human readable text.
Fields
The following are fields on the OCR tool Input tab:
• Should I Use OCR or OCV? on page 225
• Decoded String Field on page 226
• Trainer on page 227
