Parameters

Name Type Range Default Description
inImageFilNet.ImageInput image to fit arc to.
inFittingFieldFilNet.ArcFittingFieldArc 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 arc. Default value: 10.
inScanWidthint<1, INF>5The width of each scan field (in pixels). Default value: 5.
inSamplingParamsFilNet.SamplingParamsParameters controlling the sampling process.
inEdgeScanParamsFilNet.EdgeScanParamsEdgeScanParams ( ProfileInterpolation: Quadratic4 SmoothingStdDev: 1.0f MinMagnitude: 5.0f EdgeTransition: BrightToDark )Parameters controlling the edge extraction process. Default value: EdgeScanParams ( ProfileInterpolation: Quadratic4 SmoothingStdDev: 1.0f MinMagnitude: 5.0f EdgeTransition: BrightToDark ).
inEdgeSelectionFilNet.SelectionSelection mode of edges.
inLocalBlindnessFilNet.LocalBlindness?Defines conditions in which weaker edges can be detected in the vicinity of stronger edges. Default value: ftl::NIL.
inMaxIncompletenessfloat<0.0f, 0.999f>0.1fMaximal fraction of edge points not found. Default value: 0.1f.
inFittingMethodFilNet.CircleFittingMethodAlgebraicTaubinMethod used to fit an arc. Default value: AlgebraicTaubin.
inOutlierSuppressionFilNet.MEstimator?Selects a method for ignoring incorrectly detected points. Default value: ftl::NIL.
outArcFilNet.Arc2D?Fitted arc or nothing if the fitting fails.
outEdgesFilNet.NullableRef<System.Collections.Generic.List<FilNet.Edge1D?>>Found edges. Can be null to skip this parameter calculation.
outDeviationProfileFilNet.NullableRef<FilNet.NullableRef<FilNet.Profile>>Profile of distances between the actual arc points and the corresponding reference arc points. Can be null to skip this parameter calculation.
