SECTION 3
Processing Item Overview
Register the feature sections of the measurement object as an image pattern
(model), then find the most similar part to these models from the input images
to detect the position.
The correlation value showing the degree of similarity, measurement object
position, and inclination can be output.
• When identifying the shape of measurement objects (for detecting defects
or foreign matter)
21
Flexible Search Section 3-2
3-2 Flexible Search
In Flexible Search, multiple measurement object features (models) are registered beforehand.Parts from input images that most resemble the multiple
models are searched for, and correlation (similarity) and position are determined.
• To treat models with only slight variations as the same and prevent excessive filtering out.
3-2-1 Model Registration (Flexible Search)
Register the parts to measure as the model.
A total of 5 models, 0 through 4, can be registered, with no restriction on the
size.
If a model has different printing qualities and shapes, more than one models
should be registered.
The position at the time of registration is also registered in the model informa-
tion.Place the measurement object in the correct position when registering a
model.
22
Sensitive Search Section 3-3
3-3 Sensitive Search
The registered models are automatically finely divided and matched in
detail.Of the divided models, the one with the lowest correlation is output.
Sensitive search is suitable when the difference between the model image
and measurement image is small and regular searches do not produce differences in correlation.
• When identifying the shape of the divided area

ECM Search Section 3-4
3-4 ECM Search
This processing item searches the input image for parts having a high degree
of similarity to the target mark (model), and measures its correlation value
(similarity) and position.
In a normal search, image pattern models are used that look at the color and
light/dark information, but in an ECM search, models are used that look at the
profile information.Therefore, this processing assures a reliable search even
for low-contrast or noisy images.
• To measure the location of a mark

EC Circle Search Section 3-5
3-5 EC Circle Search
This processing item searches the input image for parts having a high degree
of similarity to the target circle mark (model), and measures its circle evaluated value (similarity) and position.In a normal search, image pattern models
are used that look at the color and light/dark information. In EC Circle Search,
however, models are used that look at the profile.Therefore, this processing
assures a reliable search even for low-contrast or noisy images.It is also possible to measure the number of circles in the input image.
• This counts how many circles there are of the specified size.Since circles
are extracted using the shape information in „Round“, the circles being
deformed or dirty does not affect counting.

You can specify a desired label number and obtain measurement values for
that label stored by other processing units.
The processing items that can be set up as reference objects are the following
items that perform the labeling processing.
• Labeling
Used in the Following Case
• Label position acquisition
36
Note Do not insert the following processing items between Label Data and Labeling
units.
• Camera Image Input

Defect Section 3-15
3-15 Defect
Detect defects and contamination using color variation within the measurement region.
This is real color processing, so even if defect and contamination colors
change or the background color changes, stable inspection is possible.
Used in the Following Case
• Detecting defects, contaminations and spots on plain measurement
objects
• Measure appearance defects and defects of parts

Defect Section 3-15
3-15-1 Region Setting (Defect)
PT Description
Wide line Selected when detecting defects and burrs of the measure-
ment objects.
Wide circle, wide arc Selected when detecting defects and burrs of the circle
measurement objects.
Rectangle, ellipse
(circle), polygon
Selected when detecting the overall defects of specified zones
and measurement objects.
Defect detection mechanism
• After measurement region is drawn, a rectangle (defect detection region)
is automatically formed in this region.While moving the defect detection
region around, calculate the RGB color averages at each location and find
the defect detection difference with surrounding defects. This difference is
called the defect level. Calculate the defect level for all defect detection
areas. If the maximum value exceeds the judgement value, it is judged
that there are defects in the measurement region.

6-1 Position Compensation
The positional deviation of measurement objects can be corrected using measured values saved by other processing units. Compare the measured coordinates with the reference coordinates of the applicable processing unit, and
move the image by the amount of the difference.
• Even with different positions for the same measurement object, correct
measurement can still be performed by correcting the position of the input
image.There is no need to reposition the measurement object itself.
