6. Copy the Blob tool.
a) With the Blob tool selected, click .
The tool and all of the
settings
are duplicated (copied) and all of the tools are deselected.
b) Select one of the Blob tools and click a second
time.
There are now three Blob tools with the same
settings.
7. Click Blob02 (the second Blob tool) and move the ROI over the second blister pack.
8. Click Blob03 (the third Blob tool) and move the ROI over the third blister pack.
9. Click to show all three ROI at the same
time.
10. Test a complete range of good and bad samples to make sure that the sensor accepts good parts and rejects bad parts.

Circle Detect Tool
Use the Circle Detect tool to
find
a single circle or a piece of a circle (arc).
The Circle Detect tool
finds
many edge points along the
transitions
between bright and dark pixels and then
fits
a circular shape to some
or all of these points. The tool can determine a bend radius and the circumference of a circular part. The tool
finds
only one circle within
the ROI—either the best circle (using the Best Points
option)
or the average circle (using the All Points
option).
Example
applications:
• Find
flaws
such as chips or metal spurs along a punched or drilled hole
• Measure hole size
• Measure the size of a disk
• Verify that the neck on a vial or
bottle
is the correct size
• Measure the bend radius of an electronic component
• Find the radius of a circle that is too big to
fit
