Enum CameraCalibrationFlags
Specifies available operation flags for camera calibration.
Namespace: OpenCV.Net
Assembly: OpenCV.Net.dll
Syntax
public enum CameraCalibrationFlags : intFields
| Name | Description |
|---|---|
| FixAspectRatio | Specifies that the function considers only fy as a free parameter. The ratio fx/fy stays the same as in the input camera matrix . When UseIntrinsicGuess is not set, the actual input values of fx and fy are ignored; only their ratio is computed and used further. |
| FixFocalLength | Specifies that the focal length (fx, fy) is not changed during the optimization. |
| FixK1 | Specifies that the k1 radial distortion coefficient is not changed during the optimization. If UseIntrinsicGuess is set, the coefficient from the supplied coefficients matrix is used. Otherwise, it is set to 0. |
| FixK2 | Specifies that the k2 radial distortion coefficient is not changed during the optimization. If UseIntrinsicGuess is set, the coefficient from the supplied coefficients matrix is used. Otherwise, it is set to 0. |
| FixK3 | Specifies that the k3 radial distortion coefficient is not changed during the optimization. If UseIntrinsicGuess is set, the coefficient from the supplied coefficients matrix is used. Otherwise, it is set to 0. |
| FixK4 | Specifies that the k4 radial distortion coefficient is not changed during the optimization. If UseIntrinsicGuess is set, the coefficient from the supplied coefficients matrix is used. Otherwise, it is set to 0. |
| FixK5 | Specifies that the k5 radial distortion coefficient is not changed during the optimization. If UseIntrinsicGuess is set, the coefficient from the supplied coefficients matrix is used. Otherwise, it is set to 0. |
| FixK6 | Specifies that the k6 radial distortion coefficient is not changed during the optimization. If UseIntrinsicGuess is set, the coefficient from the supplied coefficients matrix is used. Otherwise, it is set to 0. |
| FixPrincipalPoint | Specifies that the principal point is not changed during the global optimization. It stays at the center or at a different location specified when UseIntrinsicGuess is set too. |
| None | Specifies that no operation flags are active. |
| RationalModel | Coefficients k4, k5, and k6 are enabled. To provide the backward compatibility, this extra flag should be explicitly specified to make the calibration function use the rational model and return 8 coefficients. If the flag is not set, the function computes and returns only 5 distortion coefficients. |
| UseIntrinsicGuess | Specifies that some or all of the intrinsic parameters should be optimized according to the specified flags. Initial values are provided by the user. |
| ZeroTangentialDistortion | Specifies that tangential distortion coefficients (p1, p2) are set to zeros and stay zero. |
