objectPoints

Vector of vectors of the calibration pattern points.

imagePoints1

Vector of vectors of the projections of the calibration pattern points, observed by the first camera.

imagePoints2

Vector of vectors of the projections of the calibration pattern points, observed by the second camera.

K1

Input/output value, modified by the native operation. Input/output first camera intrinsic matrix: \vecthreethree{f_x^{(j)}}{0}{c_x^{(j)}}{0}{f_y^{(j)}}{c_y^{(j)}}{0}{0}{1} , j = 0,\, 1 . If any of cv::CALIB_USE_INTRINSIC_GUESS , cv::CALIB_FIX_INTRINSIC are specified, some or all of the matrix components must be initialized.

D1

Input/output value, modified by the native operation. Input/output vector of distortion coefficients \distcoeffsfisheye of 4 elements.

K2

Input/output value, modified by the native operation. Input/output second camera intrinsic matrix. The parameter is similar to K1 .

D2

Input/output value, modified by the native operation. Input/output lens distortion coefficients for the second camera. The parameter is similar to D1 .

imageSize

Size of the image used only to initialize camera intrinsic matrix.

R

Output destination, filled by the native operation. Output rotation matrix between the 1st and the 2nd camera coordinate systems.

T

Output destination, filled by the native operation. Output translation vector between the coordinate systems of the cameras.

rvecs

Output destination, filled by the native operation. Output vector of rotation vectors ( Rodrigues ) estimated for each pattern view in the coordinate system of the first camera of the stereo pair (e.g. std::vectorcv::Mat). More in detail, each i-th rotation vector together with the corresponding i-th translation vector (see the next output parameter description) brings the calibration pattern from the object coordinate space (in which object points are specified) to the camera coordinate space of the first camera of the stereo pair. In more technical terms, the tuple of the i-th rotation and translation vector performs a change of basis from object coordinate space to camera coordinate space of the first camera of the stereo pair.

tvecs

Output destination, filled by the native operation. Output vector of translation vectors estimated for each pattern view, see parameter description of previous output parameter ( rvecs ).

flags

Different flags that may be zero or a combination of the following values:

  • cv::CALIB_FIX_INTRINSIC Fix K1, K2? and D1, D2? so that only R, T matrices are estimated.
  • cv::CALIB_USE_INTRINSIC_GUESS K1, K2 contains valid initial values of fx, fy, cx, cy that are optimized further. Otherwise, (cx, cy) is initially set to the image center (imageSize is used), and focal distances are computed in a least-squares fashion.
  • cv::CALIB_RECOMPUTE_EXTRINSIC Extrinsic will be recomputed after each iteration of intrinsic optimization.
  • cv::CALIB_CHECK_COND The functions will check validity of condition number.
  • cv::CALIB_FIX_SKEW Skew coefficient (alpha) is set to zero and stay zero.
  • cv::CALIB_FIX_K1,..., cv::CALIB_FIX_K4 Selected distortion coefficients are set to zeros and stay zero.
criteria

Termination criteria for the iterative optimization algorithm.
