Add undistortImagePoints function
* Add undistortImagePoints function
undistortPoints has unclear interface and additional functionality. New function computes only undistorted image points position
* Add undistortImagePoints test
* Add TermCriteria
* Fix layout
Add distort/undistort test for fisheye::undistortPoints()
* Add distort/undistort test for fisheye::undistortPoints()
Lack of test has allowed error described in 19138 to be unnoticed.
In addition to random points, four corners and principal center
added to point set
* Add random distortion coefficients set
* Move undistortPoints test to google test, refactor
* Add fisheye::undistortPoints() perf test
* Add negative distortion coefficients to undistortPoints test, increase value
* Move to theRNG()
* Change test check from cvtest::norm(L2) to EXPECT_MAT_NEAR()
* Layout fix
* Add points number parameters, comments
Recover pose from different cameras (version 2)

Function is validated. Included an update to DISABLED_Calib3d_InitInverseRectificationMap.
Includes updates per input from @alalek and unit test regression # to reflect PR #
Update to initInverseRectificationMap()
* update to initInverseRectificationMap() documentation
* Restructured Calib3d_InitInverseRectificationMap unit test per feedback from alalek
* whitespace
Fixed trailing whitespace
Update to initInverseRectificationMap documentation for clarity
Added test case for initInverseRectificationMap()
Updated documentation.
Fixed whitespace error in docs
Small update to test function
Now passes success_error_level
final update to inverseRectification documentation
* Added CALIB_FIX_FOCAL_LENGTH to fisheye calibration #13450
Sometimes you want to calibrate just the principal point of a camera, or just the distortion coefficients. In this case, you can pass the CALIB_FIX_FOCAL_LENGTH flag to keep Fx and Fy
* Added test for CALIB_FIX_FOCAL_LENGTH option in fisheye callinration.
calib3d(usac): do not crash on empty models
* calib3d(test): regression test for issue 19639
* calib3d(usac): do not crash in setModelParameters()
* calib3d(usac): handle empty models in isModelGood()
Fisheye test has been updated to use new enum cv::fisheye::CALIB_ZERO_DISPARITY and included CV_StaticAssert(...) to ensure cv::CALIB_ZERO_DISPARITY == cv::fisheye::CALIB_ZERO_DISPARITY.
- detect case with infinite loop and raise NoConv exception
- handle such exception
- add support for case with missing `blobDetector` (image contains Point2f array of candidates)
- add regression test
- undone rectification for "failed" detections too
- drop redirectError() usage
Added SQPnP algorithm to SolvePnP
* Added sqpnp
* Fixed test case
* Added fix for duplicate point checking and inverse func reuse
* Changes for 3x speedup
Changed norm method (significant speed increase), changed nearest rotation computation to FOAM
* Added symmetric 3x3 inverse and unrolled loops
* Fixed error with SVD
* Fixed error from with indices
Indices were initialized negative. When nullspace is large, points coplanar, and rotation near 0, indices not changed.
* add findEssentialMat for two different cameras
* added smoke test for the newly added variant of findEssentialMatrix

Image sharpness, as well as brightness, are a critical parameter for
accuracte camera calibration. For accessing these parameters for
filtering out problematic calibraiton images, this method calculates
edge profiles by traveling from black to white chessboard cell centers.
Based on this, the number of pixels is calculated required to transit
from black to white. This width of the transition area is a good
indication of how sharp the chessboard is imaged and should be below
~3.0 pixels.
Based on this also motion blur can be detectd by comparing sharpness in
vertical and horizontal direction. All unsharp images should be excluded
from calibration as they will corrupt the calibration result. The same
is true for overexposued images due to a none-linear sensor response.
This can be detected by looking at the average cell brightness of the
detected chessboard.
