CalibCbType Enumeration
Type of chessboard calibration

Namespace: Emgu.CV.CvEnum
Assembly: Emgu.CV.World (in Emgu.CV.World.dll) Version: (
public enum CalibCbType
  Member nameValueDescription
Default0 Default type
AdaptiveThresh1 Use adaptive thresholding to convert the image to black-n-white, rather than a fixed threshold level (computed from the average image brightness)
NormalizeImage2 Normalize the image using cvNormalizeHist before applying fixed or adaptive thresholding.
FilterQuads4 Use additional criteria (like contour area, perimeter, square-like shape) to filter out false quads that are extracted at the contour retrieval stage
FastCheck8 If it is on, then this check is performed before the main algorithm and if a chessboard is not found, the function returns 0 instead of wasting 0.3-1s on doing the full search.
