Parameters

Name Type Range Default Description
inSurfaceFilNet.SurfaceSurface to fit the circle to.
inFittingFieldFilNet.CircleFittingFieldCircle fitting field.
inFittingFieldAlignmentFilNet.CoordinateSystem2D?Adjusts the fitting field to the position of the inspected object. Default value: ftl::NIL.
inScanCountint<3, INF>10The number of points that will be searched to estimate the position of the circle. Default value: 10.
inSamplingStepfloat?<0.0f, INF>Desired distance between consecutive sampling points on the scan segments; if Nil, the bigger of surface X and Y scales is chosen. Default value: ftl::NIL.
inScanWidthint<1, INF>5The width of each scan field (in pixels). Default value: 5.
inSurfaceInterpolationFilNet.InterpolationMethodBilinearInterpolation method used for extraction of surface points. Default value: Bilinear.
inStripeScanParamsFilNet.StripeScanParams3DStripeScanParams3D ( ProfileInterpolation: Quadratic4 SmoothingStdDev: 1.0f MinMagnitude: 5.0f MaxInnerEdgeMagnitude: Nil MinStripeWidth: 0.0f MaxStripeWidth: Nil StripePolarity: High )Parameters controlling the stripe extraction process. Default value: StripeScanParams3D ( ProfileInterpolation: Quadratic4 SmoothingStdDev: 1.0f MinMagnitude: 5.0f MaxInnerEdgeMagnitude: Nil MinStripeWidth: 0.0f MaxStripeWidth: Nil StripePolarity: High ).
inStripeSelectionFilNet.SelectionSelection mode of stripe.
inLocalBlindnessFilNet.LocalBlindness?Defines conditions in which weaker edges can be detected in the vicinity of stronger edges. Default value: ftl::NIL.
inMaxProfileGapWidthint?<0, INF>1Maximal number of consecutive not existing profile points. Default value: 1.
inMaxIncompletenessfloat<0.0f, 0.999f>0.1fMaximal fraction of stripe points not found. Default value: 0.1f.
inFittingMethodFilNet.CircleFittingMethodAlgebraicTaubinMethod used to fit a circle. Default value: AlgebraicTaubin.
inOutlierSuppressionFilNet.MEstimator?Selects a method for ignoring incorrectly detected points. Default value: ftl::NIL.
outCircleFilNet.INullable<FilNet.Circle3D>Fitted circle in the middle of found stripe or nothing if the fitting fails. This parameter cannot be null.
outInnerCircleFilNet.INullable<FilNet.Circle3D>Fitted inner circle. This parameter cannot be null.
outOuterCircleFilNet.INullable<FilNet.Circle3D>Fitted outer circle. This parameter cannot be null.
