DetectCalibrationGrid_Circles_Deprecated


Module: Calibration

Detects an arbitrary size symmetric circle pattern on the image.

Applications

Camera calibration, image to world coordinates transformations.
Name Type Range Description
inImage Image Input image
inRoi Region* Range of pixels to be processed
inCircleRadius Real 1.0 - Circle radius measured in input image pixels.
inWorldCircleSpacing Real 0.0 - Real-world distance between adjacent circles centers.
inCircleDetectionThreshold Real - - Detection threshold (relative to local image patch).
inCirclePolarity Polarity Circle intensity with respect to background.
outImagePoints Point2DArray Image coordinates of detected calibration points.
outWorldPlanePoints Point2DArray World plane coordinates of detected calibration points.
diagCirclesRegion Region Image after thresholding, this is the circle detector input.
diagCircleCandidates Point2DArray Detected circle centers, before the grid construction step.
