public static void DetectCalibrationGrid_Circles
(
	AvlNet.Image inImage,
	NullableRef<AvlNet.Region> inRoi,
	float inCircleRadius,
	float inCircleDetectionThreshold,
	AvlNet.Polarity inCirclePolarity,

)

Parameters

Name Type Range Default Description
inImageAvlNet.ImageInput image.
inRoiAvlNet.NullableRef<AvlNet.Region>Range of pixels to be processed. Default value: atl::NIL.
inCircleRadiusfloat<1.0f, INF>Circle radius measured in input image pixels.
inCircleDetectionThresholdfloat<0.0f, INF>20.0fDetection threshold (relative to local image patch). Default value: 20.0f.
inCirclePolarityAvlNet.PolarityAnyCircle intensity with respect to background. Default value: Any.
outImageGridSystem.Collections.Generic.IList<AvlNet.AnnotatedPoint2D>Detected grid.
diagCirclesRegionAvlNet.RegionImage after thresholding, this is the circle detector input.
diagCircleCandidatesSystem.Collections.Generic.IList<AvlNet.Point2D>Detected circle centers, before the grid construction step.
