8.6.4 Using the Edge and Measure Tools
Follow these steps for an example Edge
inspection
to check the
position
of a plunger in a syringe.
This procedure uses two Edge tools and a Measure tool to determine the
position
of the plunger in the barrel.
Note: This procedure is an example only.
1. Add an Edge tool to the
inspection.
2. Adjust the ROI
position,
length, and width.
a)
Position
the ROI
vertically
over the top of the plunger.
b) Expand ROI, then expand ROI Width.
c) Set the ROI width to 161 px.

3. Set the threshold.
a) Expand the Threshold parameters.
b) Set the Threshold Type to Edge Strength.
c) Leave Edge Strength at the default (20).
d) Select Bright to Dark from the Edge Polarity list.
The tool
finds
the top of the plunger.
4. Add a second Edge tool.
5. Adjust the ROI
position,
length, and width.
a)
Position
the ROI
vertically
over the top of the barrel.
b) Expand ROI, then expand ROI Width.
c) Set the ROI width to 97 px.

6. Set the threshold.
a) Expand the Threshold parameters.
b) Set the Threshold Type to Edge Strength.
c) Expand Edge Strength and set it to 21.
d) Select Dark to Bright from the Edge Polarity list.
The tool
finds
the lower edge of the barrel.
