Detailed Description

Alignment class, used to calculate the best transformation between matching pairs of points.

The object eVision.Easy3D.EFeaturesAligner contains a list of points called the 'Model points list'. The method eVision.Easy3D.EFeaturesAligner.Compute takes a second list of points as argument which is called the 'Measured points list' and produces a eVision.Easy3D.E3DTransformMatrix as result.

Member Function Documentation

◆ AlignmentType() [1/2]

eVision.Easy3D.EAlignmentType eVision.Easy3D.EFeaturesAligner.AlignmentType ( self )

eVision.Easy3D.EAlignmentType of the eVision.Easy3D.EFeaturesAligner.

By default, alignment type is eVision.Easy3D.EAlignmentType.Ordered.

◆ AlignmentType() [2/2]

eVision.Easy3D.EFeaturesAligner.AlignmentType	(		self,
		eVision.Easy3D.EAlignmentType	value )

eVision.Easy3D.EAlignmentType of the eVision.Easy3D.EFeaturesAligner.

By default, alignment type is eVision.Easy3D.EAlignmentType.Ordered.

◆ Compute() [1/2]

eVision.Easy3D.E3DTransformMatrix eVision.Easy3D.EFeaturesAligner.Compute	(		self,
		list[eVision._eVision.Easy3D.E3DPoint]	measuredPoints )

Computes the best transformation matrix for a given Measured points list.

This will compute the best transformation for the alignment between the Measured points and the Model points.

Parameters

measuredPoints The measured points list; the measured points list should at least contain 3 unaligned points.

◆ Compute() [2/2]

eVision.Easy3D.E3DTransformMatrix eVision.Easy3D.EFeaturesAligner.Compute	(		self,
		list[eVision._eVision.Easy3D.E3DPoint]	measuredPoints,
		eVision.Easy3D.EErrorStatistics	errorStatistics )

Computes the best transformation matrix for a given Measured points list.

This will compute the best transformation for the alignment between the Measured points and the Model points.

Parameters

measuredPoints	The measured points list; the measured points list should at least contain 3 unaligned points.
errorStatistics	Optional parameter passed by reference. This object will contains the error statistics (deviation between model and aligned points).

◆ Load() [1/2]

None eVision.Easy3D.EFeaturesAligner.Load	(		self,
		eVision.ESerializer \| None	serializer )

Loads the eVision.Easy3D.EFeaturesAligner object configuration.

The given eVision.ESerializer must have been created for reading.

Parameters

serializer The serializer.

◆ Load() [2/2]

None eVision.Easy3D.EFeaturesAligner.Load	(		self,
		str	path )

Loads the eVision.Easy3D.EFeaturesAligner object configuration.

The given eVision.ESerializer must have been created for reading.

Parameters

path	The file path.

◆ ModelPoints() [1/2]

list[eVision._eVision.Easy3D.E3DPoint] eVision.Easy3D.EFeaturesAligner.ModelPoints ( self )

Sets/Gets the model points list.

The model point list is a list of points that is used either as source or as destination of the transformation to calculate. The model points list should at least contain 3 unaligned points.

◆ ModelPoints() [2/2]

eVision.Easy3D.EFeaturesAligner.ModelPoints	(		self,
		list[eVision._eVision.Easy3D.E3DPoint]	value )

Sets/Gets the model points list.

The model point list is a list of points that is used either as source or as destination of the transformation to calculate. The model points list should at least contain 3 unaligned points.

◆ PolarityTransform() [1/2]

eVision.Easy3D.EAlignmentPolarity eVision.Easy3D.EFeaturesAligner.PolarityTransform ( self )

Sets/Gets the polarity of the transformation from eVision.Easy3D.EAlignmentPolarity.

Remarks:

If polarity is eVision.Easy3D.EAlignmentPolarity.ModelToMeasured, calculates the best transformation from the Model points list to the Measured points list (default).

If the polarity is eVision.Easy3D.EAlignmentPolarity.MeasuredToModel, calculates the best transformation from the Measured points list to the Model points list.

◆ PolarityTransform() [2/2]

eVision.Easy3D.EFeaturesAligner.PolarityTransform	(		self,
		eVision.Easy3D.EAlignmentPolarity	value )

Sets/Gets the polarity of the transformation from eVision.Easy3D.EAlignmentPolarity.

Remarks:

If polarity is eVision.Easy3D.EAlignmentPolarity.ModelToMeasured, calculates the best transformation from the Model points list to the Measured points list (default).

If the polarity is eVision.Easy3D.EAlignmentPolarity.MeasuredToModel, calculates the best transformation from the Measured points list to the Model points list.

◆ Save() [1/2]

None eVision.Easy3D.EFeaturesAligner.Save	(		self,
		eVision.ESerializer \| None	serializer )

Saves the eVision.Easy3D.EFeaturesAligner object configuration.

The given eVision.ESerializer must have been created for writing.

Parameters

serializer The serializer.

◆ Save() [2/2]

None eVision.Easy3D.EFeaturesAligner.Save	(		self,
		str	path )

Saves the eVision.Easy3D.EFeaturesAligner object configuration.

The given eVision.ESerializer must have been created for writing.

Parameters

path	The file path.

◆ XAngleRange() [1/2]

eVision.EFloatRange eVision.Easy3D.EFeaturesAligner.XAngleRange ( self )

Sets/Gets the range of allowed angles in eVision.Easy.SetAngleUnit between the x-axes of the model and measured referentials.

This allows to filter out symmetries when the eVision.Easy3D.EFeaturesAligner.AlignmentType is eVision.Easy3D.EAlignmentType.Unordered.
