Parameters

Name Type Range Default Description
inSurfaceAvlNet.SurfaceSurface to fit the circle to.
inFittingFieldAvlNet.CircleFittingFieldCircle fitting field.
inFittingFieldAlignmentAvlNet.CoordinateSystem2D?Adjusts the fitting field to the position of the inspected object. Default value: atl::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: atl::NIL.
inScanWidthint<1, INF>5The width of each scan field (in pixels). Default value: 5.
inSurfaceInterpolationAvlNet.InterpolationMethodBilinearInterpolation method used for extraction of surface points. Default value: Bilinear.
inStripeScanParamsAvlNet.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 ).
inStripeSelectionAvlNet.SelectionSelection mode of stripe.
inLocalBlindnessAvlNet.LocalBlindness?Defines conditions in which weaker edges can be detected in the vicinity of stronger edges. Default value: atl::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.
inFittingMethodAvlNet.CircleFittingMethodAlgebraicTaubinMethod used to fit a circle. Default value: AlgebraicTaubin.
inOutlierSuppressionAvlNet.MEstimator?Selects a method for ignoring incorrectly detected points. Default value: atl::NIL.
outCircleAvlNet.INullable<AvlNet.Circle3D>Fitted circle in the middle of found stripe or nothing if the fitting fails. This parameter cannot be null.
outInnerCircleAvlNet.INullable<AvlNet.Circle3D>Fitted inner circle. This parameter cannot be null.
outOuterCircleAvlNet.INullable<AvlNet.Circle3D>Fitted outer circle. This parameter cannot be null.
