Description

modify_component_relationsmodify_component_relationsModifyComponentRelationsModifyComponentRelationsmodify_component_relations modifies the relations between the model components within the component training result ComponentTrainingIDComponentTrainingIDComponentTrainingIDcomponentTrainingIDcomponent_training_id. The selection of the relation(s) that should be changed is performed by setting ReferenceComponentReferenceComponentReferenceComponentreferenceComponentreference_component and ToleranceComponentToleranceComponentToleranceComponenttoleranceComponenttolerance_component, respectively. This means that the relative movement of component ToleranceComponentToleranceComponentToleranceComponenttoleranceComponenttolerance_component with respect to the component ReferenceComponentReferenceComponentReferenceComponentreferenceComponentreference_component is modified.

The size of the change is specified as follows: By specifying a position tolerance PositionTolerancePositionTolerancePositionTolerancepositionToleranceposition_tolerance, the semi-axes of the rectangle that describes the reference point's movement (see train_model_componentstrain_model_componentsTrainModelComponentsTrainModelComponentstrain_model_components) are enlarged by PositionTolerancePositionTolerancePositionTolerancepositionToleranceposition_tolerance pixels. Accordingly, by specifying an orientation tolerance AngleToleranceAngleToleranceAngleToleranceangleToleranceangle_tolerance, the angle range that describes the variation of the relative orientation (see train_model_componentstrain_model_componentsTrainModelComponentsTrainModelComponentstrain_model_components) is enlarged by AngleToleranceAngleToleranceAngleToleranceangleToleranceangle_tolerance to both sides. Consequently, negative tolerance values lead to a decreased size of the relations. The operator modify_component_relationsmodify_component_relationsModifyComponentRelationsModifyComponentRelationsmodify_component_relations is particularly useful when the training images that were used during the training do not cover the entire spectrum of the relative movements.

In order to select the relations that should be modified, values for ReferenceComponentReferenceComponentReferenceComponentreferenceComponentreference_component and ToleranceComponentToleranceComponentToleranceComponenttoleranceComponenttolerance_component can be passed in one of the following ways: For each of both parameters either one value, several values, or the string 'all'"all""all""all""all" can be passed. The following table summarizes the different possibilities by giving the affected relations for different combinations of parameter values. Here, four model components are assumed (0, 1, 2, and 3). If, for example, ReferenceComponentReferenceComponentReferenceComponentreferenceComponentreference_component is set to 0 and ToleranceComponentToleranceComponentToleranceComponenttoleranceComponenttolerance_component is set to 1, then the relation (0,1), which corresponds to the relative movement of component 1 with respect to component 0, will be modified.

ReferenceComponentReferenceComponentReferenceComponentreferenceComponentreference_component	ToleranceComponentToleranceComponentToleranceComponenttoleranceComponenttolerance_component	Affected Relation(s)
'all'	'all'	(0,1) (0,2) (0,3)
		(1,0) (1,2) (1,3)
		(2,0) (2,1) (2,3)
		(3,0) (3,1) (3,2)
'all'	[1,2]	(0,1) (0,2)
		(1,2)
		(2,1)
		(3,1) (3,2)
[0,1]	'all'	(0,1) (0,2) (0,3)
		(1,0) (1,2) (1,3)
0	1	(0,1)
0	[1,2]	(0,1) (0,2)
[0,1]	2	(0,2) (1,2)
[0,1,2]	[1,2,3]	(0,1) (1,2) (2,3)

The number of tolerance values passed in PositionTolerancePositionTolerancePositionTolerancepositionToleranceposition_tolerance and AngleToleranceAngleToleranceAngleToleranceangleToleranceangle_tolerance must be either 1 or be equal to the number of affected relations. In the former case all affected relations are modified by the same value, whereas in the latter case each relation can be modified individually by passing different values within a tuple.

Execution Information

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.

This operator modifies the state of the following input parameter:

• ComponentTrainingIDComponentTrainingIDComponentTrainingIDcomponentTrainingIDcomponent_training_id

During execution of this operator, access to the value of this parameter must be synchronized if it is used across multiple threads.

Result

If the handle of the training result is valid, the operator modify_component_relationsmodify_component_relationsModifyComponentRelationsModifyComponentRelationsmodify_component_relations returns the value 2 ( H_MSG_TRUE) . If necessary, an exception is raised.
