Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
inImage | AvlNet.Image | Image to fit segment to. | |||
inFittingField | AvlNet.SegmentFittingField | Segment fitting field. | |||
inFittingFieldAlignment | AvlNet.CoordinateSystem2D? | Adjusts the fitting field to the position of the inspected object. Default value: atl::NIL. | |||
inScanCount | int | <3, INF> | 10 | The number of points that will be searched to estimate the position of the segment. Default value: 10. | |
inScanWidth | int | <1, INF> | 5 | The width of each scan field (in pixels). Default value: 5. | |
inSamplingParams | AvlNet.SamplingParams | Parameters controlling the sampling process. | |||
inEdgeScanParams | AvlNet.EdgeScanParams | EdgeScanParams ( 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 ). | ||
inEdgeSelection | AvlNet.Selection | Selection mode of edges. | |||
inLocalBlindness | AvlNet.LocalBlindness? | Defines conditions in which weaker edges can be detected in the vicinity of stronger edges. Default value: atl::NIL. | |||
inMaxIncompleteness | float | <0.0f, 0.999f> | 0.1f | Maximal fraction of edge points not found. Default value: 0.1f. | |
inOutlierSuppression | AvlNet.LineMEstimator? | Selects a method for ignoring incorrectly detected points. Default value: atl::NIL. | |||
outSegment | AvlNet.Segment2D? | Fitted segment or nothing if the fitting fails. | |||
outEdges | AvlNet.NullableRef<System.Collections.Generic.List<AvlNet.Edge1D?>> | Found edges. Can be null to skip this parameter calculation. | |||
outDeviationProfile | AvlNet.NullableRef<AvlNet.NullableRef<AvlNet.Profile>> | Profile of distances between the actual segment points and the corresponding reference segment points. Can be null to skip this parameter calculation. | |||
outAlignedFittingField | AvlNet.NullableValue<AvlNet.SegmentFittingField> | Fitting field used; in the image coordinate system. Can be null to skip this parameter calculation. | |||
outInliers | AvlNet.NullableRef<System.Collections.Generic.List<AvlNet.Point2D>> | Points matching the fitting segment. Can be null to skip this parameter calculation. | |||
outBrightnessProfiles | AvlNet.NullableRef<AvlNet.SafeList<AvlNet.Profile>> | Extracted image profiles. Can be null to skip this parameter calculation. | |||
outResponseProfiles | AvlNet.NullableRef<AvlNet.SafeList<AvlNet.Profile>> | Profiles of the edge (derivative) operator response. Can be null to skip this parameter calculation. |
