CalibType Class

Compares this instance to a specified object and returns an indication of their relative values.

Returns a value indicating whether this instance is equal to a specified object.

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.

Returns the hash code for the value of this instance.

Gets the Type of the current instance.

Returns the type code of the underlying type of this enumeration member.

Determines whether one or more bit fields are set in the current instance.

Creates a shallow copy of the current Object.

Converts the value of this instance to its equivalent string representation.

This method overload is obsolete; use ToString.

Converts the value of this instance to its equivalent string representation using the specified format.

This method overload is obsolete; use ToString(String).

The default value

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)

The focal length is fixed

Only for stereo: Fix intrinsic

The 1st distortion coefficient (k1) is fixed to 0 or to the initial passed value if CV_CALIB_USE_INTRINSIC_GUESS is passed

The 2nd distortion coefficient (k2) is fixed to 0 or to the initial passed value if CV_CALIB_USE_INTRINSIC_GUESS is passed

The 3rd distortion coefficient (k3) is fixed to 0 or to the initial passed value if CV_CALIB_USE_INTRINSIC_GUESS is passed

The 4th distortion coefficient (k4) is fixed (see above)

The 5th distortion coefficient (k5) is fixed to 0 or to the initial passed value if CV_CALIB_USE_INTRINSIC_GUESS is passed

The 6th distortion coefficient (k6) is fixed to 0 or to the initial passed value if CV_CALIB_USE_INTRINSIC_GUESS is passed

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)

Fix S1, S2, S3, S4

Fix Taux Tauy

Rational model

Only for stereo: Same focal length

Thin prism model

Tilted model

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

For stereo rectification: use LU instead of SVD decomposition for solving. much faster but potentially less precise

Use QR instead of SVD decomposition for solving. Faster but potentially less precise

For stereo rectification: Zero disparity

Tangential distortion coefficients are set to zeros and do not change during the optimization
