Members
  Member nameValueDescription
Default0 The default value
UseIntrinsicGuess1 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
FixAspectRatio2 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)
FixPrincipalPoint4 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)
ZeroTangentDist8 Tangential distortion coefficients are set to zeros and do not change during the optimization
FixFocalLength16 The focal length is fixed
FixK132 The 1st distortion coefficient (k1) is fixed to 0 or to the initial passed value if CV_CALIB_USE_INTRINSIC_GUESS is passed
FixK264 The 2nd distortion coefficient (k2) is fixed to 0 or to the initial passed value if CV_CALIB_USE_INTRINSIC_GUESS is passed
FixK3128 The 3rd distortion coefficient (k3) is fixed to 0 or to the initial passed value if CV_CALIB_USE_INTRINSIC_GUESS is passed
FixK42048 The 4th distortion coefficient (k4) is fixed (see above)
FixK54096 The 5th distortion coefficient (k5) is fixed to 0 or to the initial passed value if CV_CALIB_USE_INTRINSIC_GUESS is passed
FixK68192 The 6th distortion coefficient (k6) is fixed to 0 or to the initial passed value if CV_CALIB_USE_INTRINSIC_GUESS is passed
RationalModel16384 Rational model
ThinPrismModel32768 Thin prism model
FixS1S2S3S465536 Fix S1, S2, S3, S4
TiltedModel262144 Tilted model
FixTauxTauy524288 Fix Taux Tauy
UseQR1048576 Use QR instead of SVD decomposition for solving. Faster but potentially less precise
FixIntrinsic256 Only for stereo: Fix intrinsic
SameFocalLength512 Only for stereo: Same focal length
ZeroDisparity1024 For stereo rectification: Zero disparity
UseLU131072 For stereo rectification: use LU instead of SVD decomposition for solving. much faster but potentially less precise
