Setting the Process Conditions
Detection Conditions
Select from among Fine, Extra Fine, Medium, and Coarse for the search method.
Fine:
The search method is automatically decided based on the registered
template image and the search area size.
Extra Fine:This is effective when the image cannot be detected using the Fine search.
Searching is performed using an image with a low compression ratio from
the first stage of the search, and this makes it possible to perform more
reliable detection. However, on occasion searching can take longer than
when the Fine method is used.
Medium:
Coarse:
The final
−
stage search (searching without using a compressed image) is
eliminated so the Medium and Coarse searches are faster than their
corresponding Fine and Extra Fine searches. However, as a compressed
image is also used for the final
−
stage search, the accuracy can suffer, and
this can affect the inspection result.
Correlation minimum
The correlation value is a numerical indicator of the degree to which the target matches
the reference image. If you cannot extract characters that should be acceptable, make
the correlation minimum (Cor. Min.) smaller.
If you are extracting unwanted noise, make the correlation minimum (Cor. Min.) larger.
Template Contrast
Used to make the settings for the template image to be used for the search.
Good:
Use the registered template image (gray
−
scale image). This is the same
method used for the Smart Matching Checker.
Weak:
Uses the registered template image with enhanced contrast up until partway
through the search. With this setting it is easier to detect (compared to the
Good setting) in cases when the grayscale differentiation between the
characters and background is small.
Rotation Angle
The range over which the search is performed in the direction of rotation.
The setting range is 0 to 30
°
, and when the setting is 30, searching is performed over
the range
±
30
°
.
Delta Angle
Sets the angular step for searching over the range set in 35. Rotation Angle.
The setting range is 0 to 30, and when the setting is 5, searching is performed every
5
°
.
