Description

add_metrology_object_circle_measureadd_metrology_object_circle_measureAddMetrologyObjectCircleMeasureAddMetrologyObjectCircleMeasureAddMetrologyObjectCircleMeasureadd_metrology_object_circle_measure adds a metrology object of type circle or circular arc to a metrology model and prepares the rectangular measure regions. The handle of the model is passed in MetrologyHandleMetrologyHandleMetrologyHandleMetrologyHandlemetrologyHandlemetrology_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 circle is specified by its center (RowRowRowRowrowrow, ColumnColumnColumnColumncolumncolumn) and RadiusRadiusRadiusRadiusradiusradius. The rectangular measure regions lie perpendicular to the boundary of the circle. The half edge lengths of the measure regions are set in MeasureLength1MeasureLength1MeasureLength1MeasureLength1measureLength1measure_length_1 and MeasureLength2MeasureLength2MeasureLength2MeasureLength2measureLength2measure_length_2. The centers of the measure regions lie on the boundary of the circle. The parameter MeasureSigmaMeasureSigmaMeasureSigmaMeasureSigmameasureSigmameasure_sigma specifies the standard deviation that is used by operator apply_metrology_modelapply_metrology_modelApplyMetrologyModelApplyMetrologyModelApplyMetrologyModelapply_metrology_model to smooth the gray values of the image. Salient edges can be selected with the parameter MeasureThresholdMeasureThresholdMeasureThresholdMeasureThresholdmeasureThresholdmeasure_threshold, which constitutes a threshold on the amplitude, i.e., the absolute value of the first derivative of the edge. The operator add_metrology_object_circle_measureadd_metrology_object_circle_measureAddMetrologyObjectCircleMeasureAddMetrologyObjectCircleMeasureAddMetrologyObjectCircleMeasureadd_metrology_object_circle_measure returns the index of the added metrology object in parameter IndexIndexIndexIndexindexindex.

Furthermore, you can adjust some generic parameters with GenParamNameGenParamNameGenParamNameGenParamNamegenParamNamegen_param_name and GenParamValueGenParamValueGenParamValueGenParamValuegenParamValuegen_param_value. The following values for GenParamNameGenParamNameGenParamNameGenParamNamegenParamNamegen_param_name and GenParamValueGenParamValueGenParamValueGenParamValuegenParamValuegen_param_value are available:

'start_phi'"start_phi""start_phi""start_phi""start_phi""start_phi":

The parameter specifies the angle at the start point of a circular arc. To create a closed circle the value of the parameter 'start_phi'"start_phi""start_phi""start_phi""start_phi""start_phi" is set to 0 and the value of the parameter 'end_phi'"end_phi""end_phi""end_phi""end_phi""end_phi" is set to (with positive point order). The input value is mapped automatically to the interval .

List of values: 0.0, 0.78, 6.28318

Default value: 0.0

'end_phi'"end_phi""end_phi""end_phi""end_phi""end_phi":

The parameter specifies the angle at the end point of a circular arc. To create a closed circle the value of the parameter 'start_phi'"start_phi""start_phi""start_phi""start_phi""start_phi" is set to 0 and the value of the parameter 'end_phi'"end_phi""end_phi""end_phi""end_phi""end_phi" is set to (with positive point order). The input value is mapped internally automatically to the interval .

List of values: 0.0, 0.78, 6.28318

Default value: 6.28318

'point_order'"point_order""point_order""point_order""point_order""point_order":

The parameter specifies the direction of the circular arc. For the value 'positive'"positive""positive""positive""positive""positive", the circular arc is defined between 'start_phi'"start_phi""start_phi""start_phi""start_phi""start_phi" and 'end_phi'"end_phi""end_phi""end_phi""end_phi""end_phi" in mathematically positive direction (counterclockwise). For the value 'negative'"negative""negative""negative""negative""negative", the circular arc is defined between 'start_phi'"start_phi""start_phi""start_phi""start_phi""start_phi" and 'end_phi'"end_phi""end_phi""end_phi""end_phi""end_phi" in mathematically negative direction (clockwise).

List of values: 'positive'"positive""positive""positive""positive""positive", 'negative'"negative""negative""negative""negative""negative"

Default value: 'positive'"positive""positive""positive""positive""positive"

Additionally all generic parameters, that are available for the operator set_metrology_object_paramset_metrology_object_paramSetMetrologyObjectParamSetMetrologyObjectParamSetMetrologyObjectParamset_metrology_object_param can be set. But note that for a lot of applications the default values are sufficient and no adjustment is necessary.

Execution Information
