Description

add_metrology_object_rectangle2_measureadd_metrology_object_rectangle2_measureAddMetrologyObjectRectangle2MeasureAddMetrologyObjectRectangle2Measureadd_metrology_object_rectangle2_measure adds a metrology object of type rectangle to a metrology model and prepares the rectangular measure regions. The handle of the model is passed in MetrologyHandleMetrologyHandleMetrologyHandlemetrologyHandlemetrology_handle.

For an explanation of the concept of 2D metrology see the introduction of chapter 2D Metrology.

The geometric shape of the metrology object of type rectangle is specified by its center (RowRowRowrowrow, ColumnColumnColumncolumncolumn), the orientation of the main axis PhiPhiPhiphiphi, and the half edge lengths Length1Length1Length1length1length_1 and Length2Length2Length2length2length_2. The input value for PhiPhiPhiphiphi is mapped automatically to the interval . The rectangular measure regions lie perpendicular to the boundary of the rectangle. The half edge lengths of the measure regions perpendicular and tangential to the boundary of the rectangle are set in MeasureLength1MeasureLength1MeasureLength1measureLength1measure_length_1 and MeasureLength2MeasureLength2MeasureLength2measureLength2measure_length_2. The centers of the measure regions lie on the boundary of the rectangle. The parameter MeasureSigmaMeasureSigmaMeasureSigmameasureSigmameasure_sigma specifies a standard deviation that is used by the operator apply_metrology_modelapply_metrology_modelApplyMetrologyModelApplyMetrologyModelapply_metrology_model to smooth the gray values of the image. Salient edges can be selected with the parameter MeasureThresholdMeasureThresholdMeasureThresholdmeasureThresholdmeasure_threshold, which constitutes a threshold on the amplitude, i.e., the absolute value of the first derivative of the edge.

Furthermore, you can adjust some generic parameters within GenParamNameGenParamNameGenParamNamegenParamNamegen_param_name and GenParamValueGenParamValueGenParamValuegenParamValuegen_param_value. In particular, all generic parameters that are available in the operator set_metrology_object_paramset_metrology_object_paramSetMetrologyObjectParamSetMetrologyObjectParamset_metrology_object_param can be set. But note that for a lot of applications the default values are sufficient and no adjustment is necessary.

The operator add_metrology_object_rectangle2_measureadd_metrology_object_rectangle2_measureAddMetrologyObjectRectangle2MeasureAddMetrologyObjectRectangle2Measureadd_metrology_object_rectangle2_measure returns the index of the added metrology object within the metrology model in the parameter IndexIndexIndexindexindex.

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:

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