Parameters

Name Type Range Default Description
ioStateAvlNet.ScanMapState
inImageAvlNet.ImageInput image.
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.
inScanWidthint<1, INF>5Width of the scan field in pixels. Default value: 5.
inImageInterpolationAvlNet.InterpolationMethodBilinearInterpolation method used for extraction of image pixels. Default value: Bilinear.
inEdgeScanParamsAvlNet.EdgeScanParamsEdgeScanParams ( ProfileInterpolation: Quadratic4 SmoothingStdDev: 0.6f MinMagnitude: 5.0f EdgeTransition: BrightToDark )Parameters controlling the edge extraction process. Default value: EdgeScanParams ( ProfileInterpolation: Quadratic4 SmoothingStdDev: 0.6f MinMagnitude: 5.0f EdgeTransition: BrightToDark ).
inEdgeSelectionAvlNet.SelectionIf many edge points are possible, defines which one is selected.
inLocalBlindnessAvlNet.LocalBlindness?Defines conditions in which weaker edges can be detected in the vicinity of stronger edges. Default value: atl::NIL.
outEdgeAvlNet.Edge1D?Found edge.
outAlignedScanPathAvlNet.PathPath along which the scan is performed; in the image coordinate system.
diagBrightnessProfileAvlNet.ProfileExtracted image profile.
diagResponseProfileAvlNet.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.
diagSamplingStepfloatUsed distance between consecutive sampling points on the scan path.
