Type of chessboard calibration
Namespace: Emgu.CV.CvEnum
Assembly: Emgu.CV.World (in Emgu.CV.World.dll) Version: 4.1.1.3497 (4.1.1.3497)
SyntaxMembers| Member name | Value | Description | |
|---|---|---|---|
| Default | 0 | Default type | |
| 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 | 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. | |
| 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. |
