Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
ioState | AvlNet.ScanMapState | ||||
inImage | AvlNet.Image | Input image to be measured. | |||
inScanPath | AvlNet.Path | Path along which the scan is performed. | |||
inScanPathAlignment | AvlNet.CoordinateSystem2D? | Adjusts the scan path to the position of the inspected object. Default value: atl::NIL. | |||
inScanWidth | int | <1, INF> | 5 | Width of the scan field in pixels. Default value: 5. | |
inImageInterpolation | AvlNet.InterpolationMethod | Bilinear | Interpolation method used in extraction of image pixel values. Default value: Bilinear. | ||
inEdgeScanParams | AvlNet.EdgeScanParams | EdgeScanParams ( 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 ). | ||
inMinDistance | float | <0.0f, INF> | 0.0f | Minimal distance between consecutive edges. Default value: 0.0f. | |
inMaxDistance | float? | <0.0f, INF> | Maximal distance between consecutive edges. Default value: atl::NIL. | ||
inLocalBlindness | AvlNet.LocalBlindness? | Defines conditions in which weaker edges can be detected in the vicinity of stronger edges. Default value: atl::NIL. | |||
outEdges | System.Collections.Generic.IList<AvlNet.Edge1D> | Found edges. | |||
outGaps | System.Collections.Generic.IList<AvlNet.Gap1D> | Gaps between consecutive edges. | |||
outAlignedScanPath | AvlNet.Path | Path along which the scan is performed; in the image coordinate system. | |||
diagBrightnessProfile | AvlNet.Profile | Extracted image profile. | |||
diagResponseProfile | AvlNet.Profile | Profile of the edge (derivative) operator response. | |||
diagSamplingPoints | System.Collections.Generic.IList<AvlNet.Path> | Array of paths each one containing the sampling points that contributed to a single value of the extracted profile. | |||
diagSamplingStep | float | Used distance between consecutive sampling points on the scan path. |
