Members
| Member name | Value | Description | |
|---|---|---|---|
| DEFAULT | 0 | The default value | |
| CV_CALIB_USE_INTRINSIC_GUESS | 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 | |
| CV_CALIB_FIX_ASPECT_RATIO | 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) | |
| CV_CALIB_FIX_PRINCIPAL_POINT | 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) | |
| CV_CALIB_ZERO_TANGENT_DIST | 8 | Tangential distortion coefficients are set to zeros and do not change during the optimization | |
| CV_CALIB_FIX_FOCAL_LENGTH | 16 | The focal length is fixed | |
| CV_CALIB_FIX_K1 | 32 | The 1st distortion coefficient (k1) is fixed to 0 or to the initial passed value if CV_CALIB_USE_INTRINSIC_GUESS is passed | |
| CV_CALIB_FIX_K2 | 64 | The 2nd distortion coefficient (k2) is fixed to 0 or to the initial passed value if CV_CALIB_USE_INTRINSIC_GUESS is passed | |
| CV_CALIB_FIX_K3 | 128 | The 3rd distortion coefficient (k3) is fixed to 0 or to the initial passed value if CV_CALIB_USE_INTRINSIC_GUESS is passed | |
| CV_CALIB_FIX_K4 | 2048 | The 4th distortion coefficient (k4) is fixed (see above) | |
| CV_CALIB_FIX_K5 | 4096 | The 5th distortion coefficient (k5) is fixed to 0 or to the initial passed value if CV_CALIB_USE_INTRINSIC_GUESS is passed | |
| CV_CALIB_FIX_K6 | 8192 | The 6th distortion coefficient (k6) is fixed to 0 or to the initial passed value if CV_CALIB_USE_INTRINSIC_GUESS is passed | |
| CV_CALIB_RATIONAL_MODEL | 16384 | Rational model |
