Namespace: | AvlNet |
---|---|
Assembly: | AVL.NET.dll |
Syntax
C++
C#
public static void DetectCalibrationGrid_Circles ( AvlNet.Image inImage, NullableRef<AvlNet.Region> inRoi, float inCircleRadius, float inCircleDetectionThreshold, AvlNet.Polarity inCirclePolarity, IList<AvlNet.AnnotatedPoint2D> outImageGrid )
Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
inImage | AvlNet.Image | Input image. | |||
inRoi | AvlNet.NullableRef<AvlNet.Region> | Range of pixels to be processed. Default value: atl::NIL. | |||
inCircleRadius | float | <1.0f, INF> | Circle radius measured in input image pixels. | ||
inCircleDetectionThreshold | float | <0.0f, INF> | 20.0f | Detection threshold (relative to local image patch). Default value: 20.0f. | |
inCirclePolarity | AvlNet.Polarity | Any | Circle intensity with respect to background. Default value: Any. | ||
outImageGrid | System.Collections.Generic.IList<AvlNet.AnnotatedPoint2D> | Detected grid. |
Examples
Remarks
The circle pattern must be a rectangular grid, with equal spacing in both dimensions.
Errors
