2.4 Creating Dictionary

About Dictionary
Register character images to be the standard for Character Recognition. This registration destination is
called "Dictionary". One PV230 has 5 dictionaries. Different dictionary numbers are used according to the
font or shape of characters to be read.
In the default setting of PV230, no character data is
registered in the dictionary at all. The dictionary needs to
be created to identify a segmented image as a character
registered in the dictionary.
For creating the dictionary, specify a number from among
five dictionaries in "Dictionary Number" to register
characters. After the creation, for conducting an
inspection, specify in each checker which image pattern
of a dictionary is used for comparing to a character
segmented from an inspection image.
Dictionary provides 74 labels as follows;
Number: 0 to 9,
Alphabet: A to Z, a to z,
Symbol: 12 types
Character images are assigned in each label,
and characters and images are related.
The character image registered for each label is
called "Character Pattern", and up to 3 kinds of
character patterns can be registered.
The character cut out is compared to the images
registered for each label, and the label of the
closest image is output as the recognition
character.
The right figure shows the state when opening
"Dictionary" > "Edit".
Saving and Reading Dictionary data
Although the dictionary data that can be saved in the PV230 is up to 5 (No.0-4), a maximum of 100 sets,
as 5 dictionary data in 1 set, can be saved in a SD memory card. As dictionary data is stored in an
exclusive folder (separate from setting data), it is possible to copy only dictionary data to multiple PV230.
For saving or reading dictionary data into/from an SD memory card, select "SAVE/READ" > "SD Dictionary".
Press the ENTER key on the list, and select "Read" or "Save". Refer to page 32 for details.
Dictionary data are not saved with "Read Setting Data". Do not forget to save dictionary data in a SD card.
