How to use the Pinpoint Pattern Find tool
Click the Setup tab to use the setup for this tool.
General
1. Image: To use a different image source, click the Link button. The tool works only with greyscale
images.
2. Origin: Since this is primarily a locating tool, the tool origin should usually be 0,0,0. If there is a tool
with an output origin above this tool in the task tree, an origin may be automatically linked. Click the
link delete button to delete the link and set the origin to 0,0,0.
Train ROI
1. Train Shape List: On the Train ROI panel, move and adjust the Train Shape List so that it encloses the
part of the pattern you want to find in the image. The default shape list is a rectangle that you can move
and size. You can also create complex shapes by using circles, polygons, and exclusion regions. In this
example, the Train ROI includes the entire center portion of the image. You can also create exclusion
regions within an ROI. For example, if the text is not part of the image to inspect, click the Create
Rectangle ROI icon on the left side of the image window to create an exclusion region.
2. Train: Click the Train button to train the tool. After you make any changes to the settings or ROIs on
this panel, you need to train the pattern. If you try to leave the Train ROI panel without training the
tool, a warning is displayed. After the tool is trained, the found pattern is displayed as edge points over-
laid on the image. In the example below, the entire center portion of the image inside the Train ROI,
