Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
inSurface | AvlNet.Surface | Surface 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. | |
inSamplingStep | float? | <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. | ||
inScanWidth | int | <1, INF> | 5 | The width of each scan field (in pixels). Default value: 5. | |
inSurfaceInterpolation | AvlNet.InterpolationMethod | Bilinear | Interpolation method used for extraction of surface points. Default value: Bilinear. | ||
inEdgeScanParams | AvlNet.EdgeScanParams3D | EdgeScanParams3D ( ProfileInterpolation: Quadratic4 SmoothingStdDev: 1.0f MinMagnitude: 5.0f EdgeTransition: LowToHigh ) | Parameters controlling the edge extraction process. Default value: EdgeScanParams3D ( ProfileInterpolation: Quadratic4 SmoothingStdDev: 1.0f MinMagnitude: 5.0f EdgeTransition: LowToHigh ). | ||
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. | |||
inMaxProfileGapWidth | int? | <0, INF> | 1 | Maximal number of consecutive not existing profile points. Default value: 1. | |
inMaxIncompleteness | float | <0.0f, 0.999f> | 0.1f | Maximal fraction of edge points not found. Default value: 0.1f. | |
inOutlierSuppression | AvlNet.MEstimator? | Selects a method for ignoring incorrectly detected points. Default value: atl::NIL. | |||
outSegment | AvlNet.INullable<AvlNet.Segment3D> | Fitted segment or nothing if the fitting fails. This parameter cannot be null. |
