Angleenable property – Epson 5 User Manual

AngleEnable Property

Applies To

Vision Objects: Correlation, Geometric

Description

Specifies whether or not a correlation or geometric object will search for rotation of a feature.

Usage

VGet Sequence.Object.AngleEnable, var

VSet Sequence.Object.AngleEnable, value

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 property.

value

Boolean expression for the new value of the property.

Values

False

Do not search for rotation.

True

Search for rotation.

Default: False

Remarks

The AngleRange and AngleMaxIncrement properties will not be used with the correlation or geometric
search object if the AngleEnable property is set to False.

It should be noted that while correlation with angle is normally able to find rotated parts, the correlation
search time usually increase significantly. This is why correlation with angle is most useful for finding
parts which rotate only slightly. The Polar object however, is normally very fast and can be used in
conjunction with the Correlation object for a powerful and fast combination. (See the sections on
Correlation or Polar Searching for more information.)

The Correlation Model must be taught after the AngleEnable property is set to True. If you teach a
Correlation Model, then set the AngleEnable property to True, and then try to run that Correlation object, it
will not search with angle. You must re-teach the Correlation Model with the AngleEnable property set to
True in order for Correlation search with angle to work properly. You must also have the proper settings
for the AngleMaxIncrement and AngleRange Properties prior to teaching the new Model as well.
