Parameters Functions

Quality

Quality of each character gets a value of 0 – 100 %. As higher the value, as higher is the
confidence to the result. Small values are a sign for a bad reading quality.

Minimum
confidence

If minimum confidence was not reached the character is considered to be not read and
will be replaced by the replacement character.

Replacement
character

Output character for the case that minimum confidence was not reached.

4.6.3.12.6 Result OCR

This function executes the job defined on the PC and the Result statistics window is displayed with
Detector list and Evaluation results. Execution times are not updated in this mode, as they are not
available from the sensor.

Detector OCR, tab Quality (Page 163)

Detailed inspection results from the detector marked in the selection list are displayed in run mode.

In the image window the search- and feature areas and the result bar graphs are displayed – if set up.

Fig. 160: Detector OCR, Result display

The parameters displayed vary according to the type of detector selected:
