Parameters

Name Type Range Default Description
inSurfaceAvlNet.SurfaceInput surface.
inScanPathAvlNet.PathPath along which the scan is performed.
inScanPathAlignmentAvlNet.CoordinateSystem2D?Adjusts the scan path to the position of the inspected object. Default value: atl::NIL.
inSamplingStepfloat?<0.0f, INF>Distance between consecutive sampling points on the scan path; if Nil, the bigger of surface X and Y scales is chosen. Default value: atl::NIL.
inScanWidthint<1, INF>5Width of the scan field in pixels. Default value: 5.
inSurfaceInterpolationAvlNet.InterpolationMethodBilinearInterpolation method used for extraction of surface points. Default value: Bilinear.
inEdgeScanParamsAvlNet.EdgeScanParams3DEdgeScanParams3D ( ProfileInterpolation: Quadratic4 SmoothingStdDev: 0.6f MinMagnitude: 5.0f EdgeTransition: LowToHigh )Parameters controlling the surface edge extraction process. Default value: EdgeScanParams3D ( ProfileInterpolation: Quadratic4 SmoothingStdDev: 0.6f MinMagnitude: 5.0f EdgeTransition: LowToHigh ).
inEdgeCountint<0, INF>1Number of surface edges to be found. Default value: 1.
inEdgeSelectionAvlNet.SelectionSelection mode of the resulting edges.
inMinDistancefloat<0.0f, INF>0.0fMinimal distance between consecutive edges. Default value: 0.0f.
inMaxDistancefloat?<0.0f, INF>Maximal distance between consecutive edges. Default value: atl::NIL.
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.
outEdgesAvlNet.INullable<System.Collections.Generic.List<AvlNet.SurfaceEdge1D>>Found surface edges. This parameter cannot be null.
outAlignedScanPathAvlNet.PathPath along which the scan is performed; in the image coordinate system.
outHeightProfileAvlNet.ProfileExtracted surface height profile.
outResponseProfileAvlNet.ProfileProfile of the edge (derivative) operator response.
diagSamplingPointsSystem.Collections.Generic.IList<AvlNet.Path>Array of paths each one containing the sampling points that contributed to a single value of the extracted profile; in the image coordinate system.
diagSamplingStepfloatUsed distance between consecutive sampling points on the scan path.
