SETTING THE MEASUREMENT CONDITIONS

Coordinates mode p.75
Area judgment screen
Measure perimeter OFF (default value) When "ON", the following parameters are calculated:
• Length X
• Length Y
• Perimeter
ON
Measure roundness OFF (default value) Sets whether or not to calculate roundness.
Roundness = (4π x area)/(perimeter x perimeter)
ON
Filling up holes OFF (default value) Selects how to process parts other than the target color that are
enclosed by the target color to be measured, such as a dough-
nut. When "ON" is set, parts are processed as the target color
to be measured.
ON
Outside trimming OFF (default value) Set this function when the measurement region contains colors
other than the measurement color that are not required in mea-
surement. When "ON" is set, the entire region outside of the
measurement region is measured as the color to be measured.
ON
Area judgment 0 to 9999999.999
(default value: lower limit 0,
upper limit 307200)
Sets the minimum and maximum area values to be counted as
a label. Adjust the setting value when noise is counted as a
label by mistake.
Calibration OFF (default value)
Measurement results are output using the camera's coordinate values.
ON Measurement results are output using the coordinate value
converted by the calibration function.
Coordinates mode Normal (default value)
The position information of the input image coordinate system itself is output.
Pos. correction When position shift correction is set, the position information is
output using the coordinate system corrected to the original
state when the coordinate system was registered.
Crosshair cursors are displayed at locations in the labeling image area recognized as valid labels. Adjust the area
judgment value while checking whether or not the part to be measured is recognized correctly.
Setup Item Setting value Description

of this label
Input image Outside trimming: ON
Measurement region
The region outside of the
measurement region is taken to be the
color to be measured.
Sort mode: Area descending order
When "Label No." is set to "1", the label
