Epson 5 FoundOnEdge Result

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.
