Parameters

Name Type Range Default Description
inSurfaceAvlNet.SurfaceSurface to fit the segment to.
inFittingFieldAvlNet.SegmentFittingFieldSegment 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 segment. 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.
inRidgeScanParamsAvlNet.RidgeScanParams3DRidgeScanParams3D ( ProfileInterpolation: Quadratic4 SmoothingStdDev: 0.6f RidgeWidth: 5.0f RidgeMargin: 2.0f RidgeOperator: Minimum MinMagnitude: 5.0f RidgePolarity: Low )Parameters controlling the ridge extraction process. Default value: RidgeScanParams3D ( ProfileInterpolation: Quadratic4 SmoothingStdDev: 0.6f RidgeWidth: 5.0f RidgeMargin: 2.0f RidgeOperator: Minimum MinMagnitude: 5.0f RidgePolarity: Low ).
inRidgeSelectionAvlNet.SelectionSelection mode of ridges.
inLocalBlindnessAvlNet.LocalBlindness?Defines conditions in which weaker ridges can be detected in the vicinity of stronger ridges. 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 ridge points not found. Default value: 0.1f.
inOutlierSuppressionAvlNet.MEstimator?Selects a method for ignoring incorrectly detected points. Default value: atl::NIL.
outSegmentAvlNet.INullable<AvlNet.Segment3D>Fitted segment or nothing if the fitting fails. This parameter cannot be null.

Hardware Acceleration

This operation supports automatic parallelization for multicore and multiprocessor systems.

Hardware acceleration settings may be manipulated with Settings class.

Errors
