描述

add_metrology_object_ellipse_measureadd_metrology_object_ellipse_measureAddMetrologyObjectEllipseMeasureAddMetrologyObjectEllipseMeasureAddMetrologyObjectEllipseMeasureadd_metrology_object_ellipse_measure adds a metrology object of type ellipse or elliptic 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 二维计量.

The geometric shape of the metrology object of type ellipse is specified by its center (RowRowRowRowrowrow, ColumnColumnColumnColumncolumncolumn), the orientation of the main axis PhiPhiPhiPhiphiphi, the length of the larger half axis Radius1Radius1Radius1Radius1radius1radius_1, and the length of the smaller half axis Radius2Radius2Radius2Radius2radius2radius_2. The input value for PhiPhiPhiPhiphiphi is mapped automatically to the interval . The rectangular measure regions lie perpendicular to the boundary of the ellipse. The half edge lengths of the measure regions perpendicular and tangential to the boundary of the ellipse are set in MeasureLength1MeasureLength1MeasureLength1MeasureLength1measureLength1measure_length_1 and MeasureLength2MeasureLength2MeasureLength2MeasureLength2measureLength2measure_length_2. The centers of the measure regions lie on the boundary of the geometric shape. The parameter MeasureSigmaMeasureSigmaMeasureSigmaMeasureSigmameasureSigmameasure_sigma specifies the standard deviation that is used by the 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_ellipse_measureadd_metrology_object_ellipse_measureAddMetrologyObjectEllipseMeasureAddMetrologyObjectEllipseMeasureAddMetrologyObjectEllipseMeasureadd_metrology_object_ellipse_measure returns the index of the added metrology object in the parameter IndexIndexIndexIndexindexindex.

Furthermore, you can adjust some generic parameters within 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 an elliptic arc. The angle at the start point is measured relative to the positive main axis specified with PhiPhiPhiPhiphiphi and corresponds to the smallest surrounding circle of the ellipse. The actual start point of the ellipse is the intersection of the ellipse with the orthogonal projection of the corresponding circle point onto the main axis. The angle refers to the coordinate system of the ellipse, i.e., it is specified relative to the main axis and in a mathematical positive direction. Thus, the two main poles correspond to the angles 0 and , the two minor poles to the angle and . To create a closed ellipse 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 .

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 an elliptic arc. The angle at the end point are measured relative to the positive main axis specified with PhiPhiPhiPhiphiphi and corresponds to the smallest surrounding circle of the ellipse. The actual end point of the ellipse is the intersection of the ellipse with the orthogonal projection of the corresponding circle point onto the main axis. The angle refers to the coordinate system of the ellipse, i.e., it is specified relative to the main axis and in a mathematical positive direction. Thus, the two main poles correspond to the angles 0 and , the two minor poles to the angle and . To create a closed ellipse 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).

Default value: 6.28318

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

The parameter specifies the direction of the elliptic arc. For the value 'positive'"positive""positive""positive""positive""positive", the elliptic 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 elliptic 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).

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.
