Line Find
In the Locating and Feature Finding Drawers
The Line Find tool finds the edge points along an edge or two edges, perform a linear regression on those
points, and then create a fitted line segment along the edge (or between two edges) and an origin as an out-
put. It can find the center line between two found lines. It also checks for the maximum gap length in the
line, the maximum distance of outlying points from the line, and the line’s straightness. For more details, see
“How the Line Find tool works” on page 3-77.
Setting Up the Line Find tool (Setup is available)
1. Acquire an image of a good part.
2. Select the Wide Line ROI property and draw the ROI across the desired edge. If you are looking for the
center between two lines, be sure to draw the ROI in the appropriate direction.
3. Click Run. If necessary, adjust the inputs until the found line is located correctly and the Passed output
is True.
Correlation Model The model to find, linked from another tool
Output Name What it is
Found match If True, at least one match with a sufficient Match Score was found
Output Best Origin The best origin relative to the input tool origin
Output Best Origin
Relative to RWC
The match’s origin in Real World Coordinates. Use this value when the
Origin needs to be relative to the image for display or it needs to be
linked as another tool’s origin
Output Best Score The best model’s match score
Output Origin List A list of model origins if multiple matches were found
Output Origin List
Relative to RWC
A list of model origins relative to Real World Coordinates, if multiple
matches were found
Output Score List A list of model match scores if multiple matches were found
Input Name What it is
Input Image The image to be inspected
Tool Origin The tool’s origin relative to the entire image space
Wide Line ROI The line segment used to find the desired edge.
Line Type The tool searches in the ROI arrow direction for this type of line (see
“How the Line Find tool works” on page 3-77)
