industrial_calibration::CircleDetectorParams Struct Reference

Public Attributes
float	minThreshold = 50
	The minimum grayscale pixel intensity value at which to start the image thresholding (inclusive)
float	maxThreshold = 220
	The maximum grayscale pixel intensity value at which to stop the image thresholding (inclusive)
std::size_t	nThresholds = 18
	The number of thresholding steps to apply.
size_t	minRepeatability = 3
	The number of times a particular circle must be identified to be considered valid (must be <= the number of threshold steps)
float	circleInclusionRadius = 5
	The radius (pixels) around an identified circle within which new detected blobs will be considered to be the same feature as the circle.
float	maxRadiusDiff = 5
	The maximum difference in radius (pixels) between an identified circle and a detected blob, above which the blob will not be considered to be the same feature as the previously identified circle.
float	maxAverageEllipseError = 0.02f
	The maximum average deviation of the contour of a blob from its calculated ellipse fit (percentage)
bool	filterByColor = true
	Flag for color filtering.
uchar	circleColor = 0
	Color intensity of circle center in the binary image (value must be 0 or 255)
bool	filterByArea = true
	Flag for filtering by area.
float	minArea = 25.0f
	Minimum blob area (px^2)
float	maxArea = 5000.0f
	Maximum blob area (px^2)
bool	filterByCircularity = false
	Flag for circularity filtering.
float	minCircularity = 0.8f
	Minimum blob circularity ratio - for a perfect circle this value is 1.0 / PI (~0.333)
float	maxCircularity = std::numeric_limits<float>::max()
bool	filterByInertia = false
	Flag for inertia filtering.
float	minInertiaRatio = 0.3f
	Minimum blob inertia ratio.
float	maxInertiaRatio = std::numeric_limits<float>::max()
	Maximum blob inertia ratio - for a perfect circle, this value is 1.0.
bool	filterByConvexity = true
	Flag for convexity filtering.
float	minConvexity = 0.95f
	Minimum blob convexity.
float	maxConvexity = std::numeric_limits<float>::max()
	Maximum blob convexity.
