ChessboardFlags Enumeration

Various operation flags for cvFindChessboardCorners

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

Syntax

[FlagsAttribute]
public enum ChessboardFlags

<FlagsAttribute>
Public Enumeration ChessboardFlags

[FlagsAttribute]
public enum class ChessboardFlags

[<FlagsAttribute>]
type ChessboardFlags

Members

	Member name	Value	Description
	None	0
	AdaptiveThresh	1	Use adaptive thresholding to convert the image to black-n-white, rather than a fixed threshold level (computed from the average image brightness).
	NormalizeImage	2	Normalize the image using cvNormalizeHist before applying fixed or adaptive thresholding.
	FilterQuads	4	Use additional criteria (like contour area, perimeter, square-like shape) to filter out false quads that are extracted at the contour retrieval stage.
	FastCheck	8	Run a fast check on the image that looks for chessboard corners, and shortcut the call if none is found. This can drastically speed up the call in the degenerate condition when no chessboard is observed.
	Exhaustive	16	Run an exhaustive search to improve detection rate.
	Accuracy	32	Up sample input image to improve sub-pixel accuracy due to aliasing effects. This should be used if an accurate camera calibration is required.
