Functions

bool cv::checkChessboard (InputArray img, Size size)

Checks whether the image contains chessboard of the specific size or not.

void cv::drawChessboardCorners (InputOutputArray image, Size patternSize, InputArray corners, bool patternWasFound)

Renders the detected chessboard corners.

Scalar cv::estimateChessboardSharpness (InputArray image, Size patternSize, InputArray corners, float rise_distance=0.8F, bool vertical=false, OutputArray sharpness=noArray())

Estimates the sharpness of a detected chessboard.

bool cv::find4QuadCornerSubpix (InputArray img, InputOutputArray corners, Size region_size)

finds subpixel-accurate positions of the chessboard corners

bool cv::findChessboardCorners (InputArray image, Size patternSize, OutputArray corners, int flags=CALIB_CB_ADAPTIVE_THRESH+CALIB_CB_NORMALIZE_IMAGE)

Finds the positions of internal corners of the chessboard.

bool cv::findChessboardCornersSB (InputArray image, Size patternSize, OutputArray corners, int flags, OutputArray meta)

Finds the positions of internal corners of the chessboard using a sector based approach.

bool cv::findChessboardCornersSB (InputArray image, Size patternSize, OutputArray corners, int flags=0)

bool cv::findCirclesGrid (InputArray image, Size patternSize, OutputArray centers, int flags, const Ptr< FeatureDetector > &blobDetector, const CirclesGridFinderParameters &parameters)

Finds centers in the grid of circles.

bool cv::findCirclesGrid (InputArray image, Size patternSize, OutputArray centers, int flags=CALIB_CB_SYMMETRIC_GRID, const Ptr< FeatureDetector > &blobDetector=cv::SimpleBlobDetector::create())
