Public Shared Function FindChessboardCorners ( 
	image As InputArray,
	patternSize As Size,
	<OutAttribute> ByRef corners As Point2f(),
	Optional flags As ChessboardFlag = ChessboardFlag.Zero Or ChessboardFlag.AdaptiveThresh Or ChessboardFlag.NormalizeImage

static member FindChessboardCorners : 
        image : InputArray * 
        patternSize : Size * 
        corners : Point2f[] byref * 
        ?flags : ChessboardFlag 
(* Defaults:
        let _flags = defaultArg flags ChessboardFlag.Zero|ChessboardFlag.AdaptiveThresh|ChessboardFlag.NormalizeImage
*)
-> bool

Parameters

image: Type: OpenCvSharp.CPlusPlusInputArray
Source chessboard view. It must be an 8-bit grayscale or color image.
patternSize: Type: OpenCvSharp.CPlusPlusSize
Number of inner corners per a chessboard row and column ( patternSize = Size(points_per_row,points_per_colum) = Size(columns, rows) ).
corners: Type: OpenCvSharp.CPlusPlusPoint2f
Output array of detected corners.
flags (Optional): Type: OpenCvSharpChessboardFlag
Various operation flags that can be zero or a combination of the ChessboardFlag values

Return Value

Type: Boolean
The function returns true if all of the corners are found and they are placed in a certain order (row by row, left to right in every row). Otherwise, if the function fails to find all the corners or reorder them, it returns false.
