Setting Inspection Regions
Circles that meet the set conditions will be found from the inspection region set
here.
CHECK
When edges are extracted, the pixels at the edges of the screen cannot be
processed accurately. Do not include the outer edges of the screen when set-
ting the inspection region.
Each time the image is filtered, the range of inaccurate pixels will be increased
further. For example, if filtering is performed twice, the valid range will be
reduced as follows:
Filter size of
5
5: -2 pixels
3 = -6 pixels
Filter size of
3
3: -1 pixel
3 = -3 pixels
(Filtering is also performed once in edge extraction, so filtering is actually per-
formed a total of three times.)
CHECK
Regions can be created by combining up to 3 different figures. Regions with
difficult shapes can be drawn and sections not to be measured can be left out
of the region by combining different figures.
