Detects an arbitrary size symmetric circle pattern on the image.
|inCircleRadius||Real||1.0 -||Circle radius measured in input image pixels.|
|inWorldCircleSpacing||Real||0.0 -||Real-world distance between adjacent circles centers.|
|inCircleDetectionMinScore||Real||0.0 -||Minimum matching score for circle detector.|
|inMaxCircleSpacing||Real*||1.0 -||Maximum distance between adjacent circle centers in the image measured in pixels. Defaults to 8*inCircleRadius.|
|outImagePoints||Point2DArray||Image coordinates of detected calibration points.|
|outWorldPlanePoints||Point2DArray||World plane coordinates of detected calibration points.|
|diagCircleCandidates||Circle2DArray||Detected circles, before the grid construction step|
The circle pattern must be a rectangular grid, with equal spacing in both dimensions.
Works only for slightly distorted images (circles cannot appear as ellipses).
