Namespace: OpenCvSharp
Assembly: OpenCvSharp (in OpenCvSharp.dll) Version: 1.0.0

Syntax

public static bool FindChessboardCorners(
	InputArray image,
	Size patternSize,
	out Point2f[] corners,
	ChessboardFlags flags = ChessboardFlags.AdaptiveThresh|ChessboardFlags.NormalizeImage
)

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

public:
static bool FindChessboardCorners(
	InputArray^ image, 
	Size patternSize, 
	[OutAttribute] array<Point2f>^% corners, 
	ChessboardFlags flags = ChessboardFlags::AdaptiveThresh|ChessboardFlags::NormalizeImage
)

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

Parameters

image: Type: OpenCvSharpInputArray
Source chessboard view. It must be an 8-bit grayscale or color image.
patternSize: Type: OpenCvSharpSize
Number of inner corners per a chessboard row and column ( patternSize = Size(points_per_row,points_per_colum) = Size(columns, rows) ).
corners: Type: OpenCvSharpPoint2f
Output array of detected corners.
flags (Optional): Type: OpenCvSharpChessboardFlags
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.
