2.1 Character Recognition
General Information on Character Recognition
To recognize alphanumeric characters or symbols.
Characters such as a date or lot number are captured and search the most similar image in the image patterns
of characters already registered.
Passing status can be judged by comparing to the date and time based on the specified strings or built-in
calendar as well as outputting recognized strings to an external device.
Flow of Setup
1.Setting items relating to Inspection area. Specify a range to recognize characters.
2.Setting Segmentation condition for
characters. Set the condition to enable segmentation by one
character.
3.Creating Dictionary. Register the character images to be criteria for
Character Recognition checker.
4.Setting Inspection condition. Specify the settings for recognizing reversed
characters and for outputting recognized characters.
5.Setting Judgement condition for recognized
characters.
6.Executing Test. Check whether the recognized result is the one you
desired.

Specifying Checker No.
1. Select “Character Recognition” in "Checker Type".
2. Select the checker No. list and specify a checker
number to set.
3. Press the ENTER key to determine the checker No.
“Character Recognition” window is displayed.
About the No. of settable Character recognition checkers
The maximum number of character recognition checkers available for a type is 100. The settable number does
not change even when the number of blocks has been added.
For example, when the number of blocks has been set to "2", available character recognition checkers are 100.
As there is no restriction on the character recognition checker No. to be created, character recognition checkers
can be created in any numbers between No.0 and No.199 when the number of blocks is 2.
Selecting a Camera
Select a camera image to set a character recognition checker.
1. Select a camera No. in “Camera”.
The image of the selected camera is displayed.
Select "Switch Disp." shown by pressing the F1 key to change the displayed image type (Live/Memory and
Gray/Binary) or size.
Selecting Usage of Color Image in Inspection
Set this when using a color camera.
Select "Converted Gray Img." or "Extracted Color Img.".
Refer to Chapter 4.6 in the PV200 User's Manual for the details of setting procedure.
Selecting Position Adjustment
Position Adjustment is helpful when position or angle of an inspection object printed with characters is unstable.
Select a Position Adjustment checker that has been already set. Refer to Chapter 4.8 in the PV200 User’s
Manual for details of position adjustment.
1. Select "Position Adjustment".
The list of position adjustment is displayed.
If a position adjustment checker is not created, “PositionAdj.” cannot be selected.
2. Select a Position Adjustment No. from the list.

Setting Items relating to Inspection Area
2ch.
Setting Inspection Area
Specify a range to capture recognized characters.
If no dictionary is created, set the area for the characters to be registered in dictionary. If dictionary has
been created, set the area in the position where the characters to be read exist.
1. Select "Area Setting".
“Area Setting” window is displayed.
2. Select a shape.
Select "Rectangle" or "Doughnut" according to the
shape of recognized character string.
■Rectangle shape
■Doughnut shape
To reverse the area, press the FUNC key and select
"Counterclockwise".
The direction to cut out characers is set to either "Clockwise" or
"Counterclockwise" in "Segment Direction" under "Segment
Condition".
When using "Doughnut", the inspection results of PV230 and
PVWIN230 differ. So always adjust the inspection settings with
PV230.
3. Draw an Area.
Set an area to enclose characters.
Enter the coordinates of the area in order of a start
point and end point. Entering the end point returns
to Character recognition SETUP MENU.
A maximum of 80 characters can be recognized in
1 area.
</= 80 characters
Notice on Character Size
Adjust the lens and working distance for an appropriate view range to make
the character width larger than 10 pixels and the thickness larger than 3
pixels to perform stable character recognition.

ing Segmentation Condition for Characters

2.3 Setting Segmentation Condition for Characters
Set items in "Segmentation Condition" menu. Detecting character positions and sizes character by character
is called "Segment" characters. PV230 creates binarized images once for cutting out characters from the
background. Set the conditions for binarization and segmented characters size, etc.
Two "Conditions to segment characters" are available, which are "Image Filter" which adjusts characters to be
images that can be easily captured and "Segmentation Condition" which sets other conditions than images.
Setting Procedure
A Image Filter
Grayscale Preprocess This is a pre-processing filter for captured images. This is shared with
other checkers.
Selection and Adjustment
of Threshold method
Select and set a method to detect the pixels which make up characters.
Select one from three types of threshold methods; Fixed, Auto,
Dynamic.
Segment pre-process filter
(Dilation / Erosion) Set Dilation / Erosion filter for detected pixels. Use this function when a
character is thin, character gap is narrow, or a dotted character is used.
Slant Angle setting
Adjust the angle when the cut out characters are slanted.
It can be set between -45.00 and +45.00 degrees.
Slant Angle setting is available only for Rectangle shape.
B Segmentation Condition
Limitation of Character size
(Area / Width / Height)
It is helpful in eliminating objects larger or smaller
than characters.
Segment Direction
Set the direction of characters.
Boundary
Objects at the top of the frame of Inspection area
are eliminated from the objects for
segmentation.
Partition
It is helpful in segmenting closely adjacent
characters that cannot be separated by Segment
Pre-process Filter.
Limitation of Character size
(Area / Width / Height)
It is helpful in eliminating objects larger or smaller than
characters.

18
Setting Segmentation
Condition for Characters
2ch.
Point to be checked for character segmentation before
registration in dictionary
Confirm if the character is surrounded with a square. At this time, the square should be placed as close to
the character as possible. The common cases of character segmentation are as follows.
- Characters are not segmented.
Adjust the settings of binarization and segment pre-process filter in the
"Image Filter" menu.
- A stain or a burr is also in the box.
Adjust the setting of binarization to prevent stains or burrs from being in
boxes. If a character with an unnecessary object is
registered in the
dictionary, it is recognized as the correct sample. So, capture a clean object
as much as possible for the registration in the dictionary.
- "i" or "j" is divided into multiple boxes.
Adjust using "Segment pre-process filter". Make multiple boxes into a single
box by increasing filter Y with "Dilation".
- Although characters are surrounded wit
h boxes, there are some
holes.
When characters are completely surrounded, it does not matter if there are
spotty parts in red areas. The red areas are for identifying the sizes of
characters. Those grayscale images surrounded with boxes are used for the
dictionary and used as objects for inspections.
- Adjacent characters are in the same box.
This case is no problem.
Select "Yes" for "Partition" under "Segment
Condition", and set a size approx. 1.5 times larger than the character width
in "Character Width". Refer to page 25 for details
- If a character joins another character or an object by "Segmentation",
those characters cannot be segmented.
Change the printed position of the characters. In the left-hand figure, "j" and
"t" cannot be segmented as they are too close.
Confirming Segmented Characters
About <F2> and <F3> Keys
Pressing the F3 key while various items for Segmentation condition are set displays the result of "Segment
pre-process filter", and pressing the F2 key displays the final result of segmentation.Use the F2 or F3 key for
checking the segmentation results and for adjusting each segmentation condition.
