SyntaxMembers| Member name | Value | Description | |
|---|---|---|---|
| Default | 0 | The default value | |
| UseIntrinsicGuess | 1 | intrinsic_matrix contains valid initial values of fx, fy, cx, cy that are optimized further. Otherwise, (cx, cy) is initially set to the image center (image_size is used here), and focal distances are computed in some least-squares fashion | |
| FixAspectRatio | 2 | The optimization procedure consider only one of fx and fy as independent variable and keeps the aspect ratio fx/fy the same as it was set initially in intrinsic_matrix. In this case the actual initial values of (fx, fy) are either taken from the matrix (when CV_CALIB_USE_INTRINSIC_GUESS is set) or estimated somehow (in the latter case fx, fy may be set to arbitrary values, only their ratio is used) | |
| FixPrincipalPoint | 4 | The principal point is not changed during the global optimization, it stays at the center and at the other location specified (when CV_CALIB_FIX_FOCAL_LENGTH - Both fx and fy are fixed. CV_CALIB_USE_INTRINSIC_GUESS is set as well) | |
| ZeroTangentDist | 8 | Tangential distortion coefficients are set to zeros and do not change during the optimization | |
| FixFocalLength | 16 | The focal length is fixed | |
| FixK1 | 32 | The 1st distortion coefficient (k1) is fixed to 0 or to the initial passed value if CV_CALIB_USE_INTRINSIC_GUESS is passed | |
| FixK2 | 64 | The 2nd distortion coefficient (k2) is fixed to 0 or to the initial passed value if CV_CALIB_USE_INTRINSIC_GUESS is passed | |
| FixK3 | 128 | The 3rd distortion coefficient (k3) is fixed to 0 or to the initial passed value if CV_CALIB_USE_INTRINSIC_GUESS is passed | |
| FixK4 | 2048 | The 4th distortion coefficient (k4) is fixed (see above) | |
| FixK5 | 4096 | The 5th distortion coefficient (k5) is fixed to 0 or to the initial passed value if CV_CALIB_USE_INTRINSIC_GUESS is passed | |
| FixK6 | 8192 | The 6th distortion coefficient (k6) is fixed to 0 or to the initial passed value if CV_CALIB_USE_INTRINSIC_GUESS is passed | |
| RationalModel | 16384 | Rational model | |
| ThinPrismModel | 32768 | Thin prism model | |
| FixS1S2S3S4 | 65536 | Fix S1, S2, S3, S4 | |
| TiltedModel | 262144 | Tilted model | |
| FixTauxTauy | 524288 | Fix Taux Tauy | |
| UseQR | 1048576 | Use QR instead of SVD decomposition for solving. Faster but potentially less precise | |
| FixIntrinsic | 256 | Only for stereo: Fix intrinsic | |
| SameFocalLength | 512 | Only for stereo: Same focal length | |
| ZeroDisparity | 1024 | For stereo rectification: Zero disparity | |
| UseLU | 131072 | For stereo rectification: use LU instead of SVD decomposition for solving. much faster but potentially less precise |
