FoundOnEdge Result
FoundOnEdge Result
Applies To
Vision Objects: Blob, Correlation, Geometric
Description
Returns True when a Blob, Correlation, or Geometric object is found too close to the edge of the search
window.
Usage
VGet Sequence.Object.FoundOnEdge [(result)], var
Sequence Name of a sequence or string variable containing a sequence name.
Object Name of an object or string variable containing an object name. The object must exist in the
specified sequence.
var Boolean variable that will contain the value of the result.
result Optional result number. If omitted, the result number is the CurrentResult.Used for objects
that return multiple results.
Values
False The part was not found at the edge of the search window
True The part was found at the edge of the search window
Remarks
The FoundOnEdge result is a special status which works only with the Blob, Correlation, and Geometric
objects. It tells the user why a specific Blob, Correlation, or Geometric object is not Found.
Sometimes the Vision System tries to report that a Blob, Correlation, or Geometric object was found even
though part of the object may be located outside of the Field of View. Rather than report these objects as
Found, Vision Guide returns False for the Found result when a Blob, Correlation, or Geometric object is
found but part of the object is outside of the Search Window.
If you want to reject a part when FoundOnEdge is True, set the RejectOnEdge property to True.
There will be cases where you will use a Correlation object and the Found result continues to return False
even though the Score result for the object is well below the Accept property. In these situations, check the
FoundOnEdge result and RejectOnEdge property. This will tell you that the part was in fact found by the
Vision System but that Vision Guide will not return the results because the part or object is outside of the
Field of View when the picture was taken.
