Cog3DCheckerboardFeatureExtractor Class

Cognex VisionPro 9.7

This class defines a Cognex checkerboard calibration feature extractor. This extractor extracts the calibration features from an image of a Cognex checkerboard calibration plate.

Methods

	Name	Description
	CreateObjRef	Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.)
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Execute(List List ICogImage )	Extract features from a set of calibration images, acquired from one or multiple cameras over different calibration plate poses. The images are organized in a List, indexed by calibration plate pose. Each item in the list is a List of images, indexed by camera. It is expected that the fiducial defining the calibration plate's origin is within the field of view. The feature extraction is done by calling the Execute( ICogImage ) method for each calibration image. The Execute( ICogImage ) method will be invoked on multiple threads if the IsThreadSafe property is true. The FeaturesExtracted event is fired after the featues are extracted from each image. (Inherited from Cog3DCalibrationFeatureExtractorBase.)
	Execute(ICogImage)	Extracts features from a Cognex checkerboard calibration plate image. The fiducial defining the calibration plate's origin, must be within the field of view or an exception is thrown. (Overrides Cog3DCalibrationFeatureExtractorBase Execute(ICogImage).)
	Finalize	Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetAttributes	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetClassName	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetComponentName	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetConverter	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetDefaultEvent	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetDefaultProperty	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetEditor	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetEvents	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetEvents( Attribute )	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetLifetimeService	Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
	GetObjectData	Implements the GetObjectData method of the ISerializable interface. (Inherited from CogSerializableObjectBase.)
	GetProperties	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetProperties( Attribute )	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetPropertyOwner	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	InitializeLifetimeService	Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	MemberwiseClone(Boolean)	Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject.)
	OnFeaturesExtracted	Method to support feature extraction progress event. (Inherited from Cog3DCalibrationFeatureExtractorBase.)
	ToString	Returns a String that represents the current Object. (Inherited from Object.)

Properties

	Name	Description
	Algorithm	Gets/sets the algorithm to be used for feature finding.
	DataMatrixTimeout	The maximum time in milliseconds to search for a single DataMatrix fiducial.
	DataMatrixTimeoutEnabled	If True, use the DataMatrixTimeout value when LabelMode is either DataMatrix or DataMatrixWithGridPitch.
	IsThreadSafe	Gets whether the implementation of the Execute(ICogImage) method is thread-safe. thread-safety is required to allow multithreading within implementations of the Execute(List< List< ICogImage > >) method. (Overrides Cog3DCalibrationFeatureExtractorBase IsThreadSafe.)
	LabelMode	Gets/sets the style of fiducial mark to be found on the Cognex calibration plate.
	PhysGridPitch	Gets/sets the physical grid pitch of the Cognex checkerboard calibration plate.

Events

	Name	Description
	FeaturesExtracted	Feature extraction progress event. (Inherited from Cog3DCalibrationFeatureExtractorBase.)
