AVL.CreateArcFittingMap(AvlNet.ImageFormat, AvlNet.ArcFittingField, AvlNet.CoordinateSystem2D?, int, int, AvlNet.InterpolationMethod, AvlNet.ArcFittingMap, AvlNet.Segment2D[], AvlNet.Rectangle2D[])

Precomputes a data object that is required for fast arc fitting on images.

Namespace:AvlNet
Assembly:AVL.NET.dll

Syntax


public static void CreateArcFittingMap(
	AvlNet.ImageFormat inImageFormat,
	AvlNet.ArcFittingField inFittingField,
	AvlNet.CoordinateSystem2D? inFittingFieldAlignment,
	int inScanCount,
	int inScanWidth,
	AvlNet.InterpolationMethod inImageInterpolation,
	out AvlNet.ArcFittingMap outFittingMap,
	out AvlNet.Segment2D[] diagScanSegments,
	out AvlNet.Rectangle2D[] diagSamplingAreas
)

Parameters

inImageFormat
Type: AvlNet.ImageFormat
Dimensions, depth and pixel type of the images on which fitting will be performed
inFittingField
Type: AvlNet.ArcFittingField
Defines a ring section in which scan segments will be created
inFittingFieldAlignment
Type: System.Nullable<AvlNet.CoordinateSystem2D>
Adjusts the fitting field to the position of the inspected object, or null.
inScanCount
Type: System.Int32
The number of points that will be searched to estimate the position of the arc
inScanWidth
Type: System.Int32
The width of each scan field (in pixels)
inImageInterpolation
Type: AvlNet.InterpolationMethod
Interpolation method used for extraction of image pixel values
outFittingMap
Type: AvlNet.ArcFittingMap
Optimized data required for arc fitting
diagScanSegments
Type: AvlNet.Segment2D
Segments along which the scans will be run
diagSamplingAreas
Type: AvlNet.Rectangle2D
Scan fields created for point detection

Description

The operation creates a series of scan maps that can be later used by other Shape Fitting filters. Each scan map corresponds to a single scan segment of inScanWidth length.

The optional parameter inFittingFieldAlignment defines the transform to be performed on the inFittingField so that the result is defined in a new context, e.g. returned by one of Template Matching filters.
