Type of chessboard calibration

[Flags]
public enum CalibCbType

Fields

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.

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)

Default = 0

Default type

Exhaustive = 16

Run an exhaustive search to improve detection rate.

FastCheck = 8

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.

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

NormalizeImage = 2

Normalize the image using cvNormalizeHist before applying fixed or adaptive thresholding.
