Detects a chessboard calibration grid on the image, and returns calibration points where 4 chessboard squares meet.
|inBoardSize||Size||Number of checkerboard squares in X and Y dimensions.|
|inWorldSquareSize||Real||0.001 -||Real-world length of a single chessboard square.|
|inFastApproximate||Bool||Fast filter execution, but result is approximate.|
|outImagePoints||Point2DArray?||Image coordinates of detected calibration points.|
|outWorldPlanePoints||Point2DArray?||World plane coordinates of detected calibration points.|
This filter can throw an exception to report error. Read how to deal with errors in Error Handling.
List of possible exceptions:
|DomainError||Input image is too small|
|DomainError||Input image must have pixels of UInt8 type|
|DomainError||Specified board is too small, minimum size is 4x4|
