[Factory default]
Difference image is used as is in this method.
When the image of the registered model and the target object after
application can be taken at the same exact position, there is no position
• [Checked] difference between the images so no noise is generated by image
subtraction.
In this case, measurement can be performed more accurately when a
difference image is used as is.
The preset pixel values are deleted from the outline of the extracted
difference image in this method.
Set this method to remove noise caused by position difference of images
when the inspection target or camera slightly moves.
The application width is measured to be narrower than the actual width
because information of several pixels is deleted from the difference
image.
• Unchecked
0 to 9 Select the degree of assimilation of variations around boundaries.
[3] The function differs depending on the "Boundary inspection" setting.
Set the degree of tolerance for brightness variations.
When the tolerance is set to 0, no brightness variation is accepted.
0.00 to 100.00
Therefore, images are more easily affected by lighting fluctuations.
[2.00]
If this value is increased the range of allowable variation increases so it
can become more difficult to extract differences.
