AVL.CreateCircleFittingMap
Precomputes a data object that is required for fast circle fitting on images.
Namespace: | AvlNet |
---|---|
Assembly: | AVL.NET.dll |
Syntax
public static void CreateCircleFittingMap ( AvlNet.ImageFormat inImageFormat, AvlNet.CircleFittingField inFittingField, AvlNet.CoordinateSystem2D? inFittingFieldAlignment, int inScanCount, int inScanWidth, AvlNet.InterpolationMethod inImageInterpolation, AvlNet.CircleFittingMap outFittingMap )
Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
inImageFormat | AvlNet.ImageFormat | Dimensions, depth and pixel type of the images on which fitting will be performed. | |||
inFittingField | AvlNet.CircleFittingField | Defines a ring in which scan segments will be created. | |||
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 circle. Default value: 10. | |
inScanWidth | int | <1, INF> | 5 | The width of each scan field (in pixels). Default value: 5. | |
inImageInterpolation | AvlNet.InterpolationMethod | avl::InterpolationMethod::NearestNeighbour | Interpolation method used for extraction of image pixel values. Default value: avl::InterpolationMethod::NearestNeighbour. | ||
outFittingMap | AvlNet.CircleFittingMap | Optimized data required for circle fitting. |
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.
