Impact Reference Guide Circular Pattern Find
3-71 Datalogic Automation Inc.
• Widen Arc
• Rotate
Do not change the arc ROI’s width between training and running, only the arc length. Generally, a thinner
arc executes faster.
The tool can find multiple matches within the search ROI and the best match and a list of all matches are
available as outputs.
Note: You cannot see the trained model. That is, after you train and then resize the arc for searching, you can
not see the trained arc angle.

NOTE: This tool has been deprecated and replaced by the Pinpoint Pattern Find tool (see page 3-84). It is
documented here only for existing vision programs and is no longer supported.
Input Name What it is
Input Image The image being inspected
Tool Origin The tool’s origin relative to the entire image space
Arc Region The region of the image used to train the model.
Minimum Match
Score
Found Match is false if no pattern is found with a match score larger than
this (0 to 100)
Reference Angle
Method
Center of Model Arc: The model is trained to report at the center of the
arc region.
0 Degrees: The model is trained to report 0 degrees at the trained orien-
tation.
Correlation Model The model to find, linked from another tool
Output Name What it is
Found Match True when a model with a score greater than the Minimum Match Score
is found
Output Best Origin The model’s origin relative to the input tool origin
Output Best Origin
Relative to RWC
The model’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 match score greater than the Minimum Match Score (1 to 100)
Output Origin List List of Origins relative to the input tool origin
Output Origin List
Relative to RWC
List of Origins relative to Real World Coordinates
Output Score List The match scores of origins in the Origin List
