Vision Properties and Results Reference
Overview
This reference manual explains all Vision Guide sequence, object, and calibration properties and
results, and all Vision Guide SPEL+ commands. For more information on how to use Vision Guide,
refer to the Vision Guide manual.
Vision Properties and Results Format Description
All Vision Guide properties and results are listed in the pages that follow. An explanation of the
headings for the property and result reference pages is given below:
Applies To
Description
Usage
Values
Remarks
See Also
Runtime only
If the property or result is used with vision objects, then this section simply lists
the vision objects for which this property applies. (Ex. Blob, Correlation,
Polar...)
If the property or result is used with vision sequences then the words Vision
Sequence will appear in this section.
If the property or result is used with vision calibration then the words Vision
Calibration will appear in this section.
A simple description is given for each property or result. This section is
normally very short for simplicity.
The Usage Section describes how to access the property or result from the
+
Language.
SPEL
Describes the range of acceptable values which the property can be set to or
which the result will return. A default value is also shown for those properties
that have a default.
Explains more details than the Description Section. This section is normally
used to describe any caveats or special information that may apply to the
specific property or result. (It is highly recommended to read the Remarks
Section for each property prior to its usage.)
Gives a list of related properties, results, vision objects and other topics that may
prove useful to review.
This is displayed under the property or result name when it applies. Runtime
only properties and results cannot be accessed from the Vision Guide GUI.
They can only be accessed from the SPEL+ language or from VB Guide.
Vision Guide 5.0 Reference (Ver.5.3) Rev.1 1
AbortSeqOnFail Property
AbortSeqOnFail Property
Applies To
Vision Objects: Blob, Geometric, Correlation, Edge, Freame, Line, Point, Polar
Description
Allows the user to specify that if an object fails (i.e. is not found), then the entire sequence is aborted at that
point and no further objects are processed.
Usage
VGet Sequence.Object.AbortSeqOnFail, var
VSet Sequence.Object.AbortSeqOnFail, 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 Does not cause the sequence to abort when the object is not found.
True Causes the sequence to abort when the object is not found.
Default: False
Remarks
Use AbortSeqOnFail when you no longer want a sequence to continue if an object is not found.
See Also
Blob Object, Correlation Object, Edge Object, Frame Object, Geometric Object, Line Object, Point Object,
Polar Object, Object Tab
2 Vision Guide 5.0 Reference (Ver.5.3) Rev.1
Accept Property
Accept Property
Applies To
Vision Objects: Correlation, Edge, Geometric, Polar
Description
The Accept property specifies the score that a feature must equal or exceed to be considered found.
Usage
VGet Sequence.Object.Accept, var
VSet Sequence.Object.Accept, 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 Integer variable that will contain the value of the property.
value Integer expression for the new value of the property.
Values
Integer number from 1 - 999
Default: 700 - Correlation, Geometric, Polar
100 - Edge
Remarks
The Accept property can also affect the searching speed by providing a hint as to when to pursue the search
in a given area of the Region of Interest. When the Accept property is high, features must be very similar
to the model, so many regions can be ruled out by a cursory examination and not pursued further. However,
if the Accept property is low, features that are only slightly similar to the model may exceed the Accept
property, so that a detailed examination of more regions in the scene is needed. Thus, raising the Accept
property tends to reduce the time required for searches.
If the specified value is small, it may result in false detection.

Angle Result
Applies To
Vision Objects: Blob, Correlation, Frame, Geometric, Line, Polar
Description
Returns the angle of the found object.
Usage
VGet Sequence.Object.Angle[(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 Real variable that will contain the value of the result.

that return multiple results.
Values
Real number in degrees
Blob : −90 to 90 degree
Others ： 0 to 360 degree
Remarks
The Angle result returns the found part's angle in the image coordinate system. In some cases, you may
want to use a Polar object to determine angle because it can be faster and more accurate.
Statistics
For the Angle result, the following statistics are available. AngleMax, AngleMean, AngleMin,
AngleRange, AngleStdDev. Please see Statistics in the Vision Guide manual for details about using
statistics.

AngleAccuracy Property
AngleAccuracy Property
Applies To
Vision Objects: Correlation
Description
Specifies the accuracy of a correlation search with rotation.
Usage
VGet Sequence.Object.AngleAccuracy, var
VSet Sequence.Object.AngleAccuracy, 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 Real variable that will contain the value of the property.
NOTE
)
value Real expression for the new value of the property.
Values
Real number in degrees from 0.1 - 10
Default: 1
Remarks
The AngleAccuracy property is used at model training time and not at run-time. This value specifies the
desired accuracy for angle search.
The Correlation model must be taught after a new value for the AngleAccuracy property is set in order for
the new setting to take affect. If you teach a Correlation Model, then later set the AngleAccuracy property
to a new value, and then try to run that Correlation object, it will not search with the new angle accuracy.
You must re-teach the Correlation Model with the AngleEnable property set to True, and with the new
value for the AngleAccuracy property in order for Correlation search with angle to use the new
AngleAccuracy property value.

AngleMaxIncrement Property, AngleRange Property, Angle Result, Correlation Object, Object Tab
Vision Guide 5.0 Reference (Ver.5.3) Rev.1 7
AngleEnable Property
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.
Values
Remarks
NOTE
)
value Boolean expression for the new value of the property.
False Do not search for rotation.
True Search for rotation.
Default: False
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.

8 Vision Guide 5.0 Reference (Ver.5.3) Rev.1
AngleMaxIncrement Property
AngleMaxIncrement Property
Applies To
Vision Objects: Correlation
Description
The AngleMaxIncrement property specifies the maximum angle increment amount for teaching a
correlation model for searching with angle. The model training function selects an angular increment
automatically and then uses the smaller of the automatically selected increment and the maximum angle
increment defined by the AngleMaxIncrement property.
Usage
VGet Sequence.Object.AngleMaxIncrement, var
VSet Sequence.Object.AngleMaxIncrement, 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.
NOTE
)
var Real variable that will contain the value of the property.
value Real expression for the new value of the property.
Values
Real number in degrees from 1 - 45
Default: 1
Remarks
Before reading anything else about the AngleMaxIncrement property it should be noted that the Correlation
Model must be taught after a new value for the AngleMaxIncrement property is set in order for those
settings to take affect. If you teach a Correlation Model, then later set the AngleMaxIncrement property to
a new value, and then try to run that Correlation object, it will not search with the new angle increment.
You must re-teach the Correlation Model with the AngleEnable property set to True, and with the new
value for the AngleMaxIncrement property in order for Correlation search with angle to use the new
AngleMaxIncrement property value. You must also have the proper settings for the AngleRange property
prior to teaching the new Model as well.
If you wish to measure angle precisely, you should provide a maximum angle increment corresponding to
the degree of precision you desire. You should keep in mind, however, that the smaller the angle increment,
the more storage will be required for the model and the slower the search time will be.
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 a Correlation object for a powerful and fast combination. (See the sections on Correlation
or Polar Searching for more information.)

operation.
Usage
VGet Sequence.Object.AngleObject, var
VSet Sequence.Object.AngleObject, 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 String variable that will contain the value of the property.
value String expression for the new value of the property.
Values

returns an Angle result.
Default: Screen
Remarks
Use AngleObject together with the Rotate setting of the Operation property to automatically rotate the

AngleOffset Property
AngleOffset Property
Applies To
Vision Objects: Polar
Description
An angle value which is used as an offset to line up the Polar Search direction indicator (graphic line on the
image display) with the part since it is virtually impossible and normally impractical to teach a polar object
with the proper rotation of a part so that the direction lines up with the part.
Usage
VGet Sequence.Object.AngleOffset, var
VSet Sequence.Object.AngleOffset, 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 Real variable that will contain the value of the property.
value Real expression for the new value of the property.
Values
Real number in degrees from 0 - 360
Default: 0
Remarks
The AngleOffset is provided to allow the Polar object's graphic direction indicator to line up with a specific
area on a part. The graphic direction indicator is normally set at the default position for the polar object
which is 0 degrees (at 3 O'clock). The rotation for the AngleOffset property is then defined in a counter
clockwise direction.

AngleRange Property
AngleRange Property
Applies To
Vision Objects: Correlation, Geometric
Description
Specifies the range within which to train a series of rotated models.
Usage
VGet Sequence.Object.AngleRange, var
VSet Sequence.Object.AngleRange, 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 Integer variable that will contain the value of the property.
Values
Remarks
NOTE
)
value Integer expression for the new value of the property.
Integer number in degrees from 0 - 180
Default: 180
Before reading anything else about the AngleRange property it should be noted that the Correlation Model
must be taught after a new value for the AngleRange property is set in order for those settings to take affect.
If you teach a Correlation Model, then later set the AngleRange property to a new value, and then try to run
that Correlation object, it will not search with the new angle range. You must re-teach the Correlation
Model with the AngleEnable property set to True, and with the new value for the AngleRange property in
order for Correlation search with angle to use the new AngleRange property value. You must also have the
proper settings for the AngleMaxIncrement property prior to teaching the new Model as well.
The AngleRange property is must be set before teaching the model. This value specifies the range within
which to train a series of rotated models. For example, if the AngleRange property is set to 5, then when
the model is trained, a set of models is actually trained within +/- 5 degrees of the current model position.
These models are then used when a correlation search with angle is specified.
It should be noted that using correlation with angle will generally cause the correlation time to increase
significantly. This is why correlation with angle is normally used for small angle increments only. 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 in the Vision Guide
Manual for more information.)
Specify a small value for the setting. If the value is large, the detection time gets longer and may result in
false detection.

AngleStart Property
AngleStart Property
Applies To
Vision Objects: Correlation, Geometric
Description
Sets / returns the starting search angle.
Usage
VGet Sequence.Object.AngleStart, var
VSet Sequence.Object.AngleStart, 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 Integer variable that will contain the value of the property.
value Integer expression for the new value of the property.
Values
Integer number in degrees from 0 - 360
Default: 0
Remarks
Use AngleStart to set the starting search angle. This property is only valid when AngleEnable is set to True.
The system will search for the model starting with AngleStart using the AngleRange property. For
example, if AngleStart is 45 degrees and AngleRange is 10 degrees, then the system will search from 35 to
55 degrees.
Note that after setting AngleStart, the model will be automatically preprocessed on the next run, which
could cause slower cycle time on that first run. Subsequent cycle times will be at normal speed.
