what better than Gradient Edges when the edge is a gradual slope, the flat parts of the image are noisy, or
you are trying to find more subtle edges.
Origin
In the Locating Drawer
The Origin tool uses from one to three line ROIs to locate image edges. These edges provide an origin point
and angle for other tools to use as a reference point to locate the parts of the image you want to inspect. Use
this tool when the parts of the image to be inspected may move within the image window. After the tool is
trained and run, the Output Origin can be linked into the Tool Origin property of other tools.
Notes: When a tool with a Tool Origin input property is put in a task, that input property value is linked to
the same value that was last used by other tools in the task.
The Origin tool, unlike other tools, clips ROIs that fall partially off the image. Since it is a locating tool and
its ROIs can dynamically position relative to each other, ROI off-image situations can happen and not be
errors.
A Setup is available for this tool, which simplifies basic configuration. Click the Setup tab to use it.
Input Name What it is
Input Image Linked Image
Tool Origin The tool’s origin relative to the entire image space. Type or link a value
into this property if you are trying to find an origin relative to another tool.
Origin Type One Direction: Primary ROI is used
One Direction And Angle: Primary and Secondary ROIs used
Two Directions: Primary and Perpendicular ROIs used

No Relative ROI Positioning: Each ROI is positioned based on edges
found
Find Primary Edge, Then Position Perpendicular ROI: When the Primary
ROI is positioned, and a point is found, the Perpendicular ROI is posi-
tioned relative to the found point
Find Perpendicular Edge, Then Position Primary ROI: When the Perpen-
dicular ROI is positioned, and a point is found, the Primary ROI is posi-
tioned relative to the found point
Primary ROI This is the primary locator ROI. Use this ROI alone if you are searching
for a single edge in one direction. Place it perpendicular to the edge you
want to find.
