Alexander Duda	d594e72586	fix: estimateChessboardSharpness triggers out of range test Problem is that iter1 += tcols, iter2 += tcols are called without check. row < trows - 1 check is processed after increment in "for" statements.	5 years ago
Alexander Duda	44560c3e50	calib3d: add estimateChessboardSharpness 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.	5 years ago
Eduard Trulls	7e637c134f	Expose maxIters in findFundamentalMat Lets the user choose the maximum number of iterations the robust estimator runs for, similary to findHomography. This can significantly improve performance (at a computational cost).	5 years ago
Maksim Shabunin	bf96d8239d	Use BufferArea in more places	5 years ago
Alexander Duda	a41cbbdc99	findChessboardCornersSB: performance + support for full FOV boards with markers Changes: * UMat for blur + rotate resulting in a speedup of around 2X on an i7 * support for boards larger than specified allowing to cover full FOV * support for markers moving the origin into the center of the board * increase detection accuracy The main change is for supporting boards that are larger than the FOV of the camera and have their origin in the board center. This allows building OEM calibration targets similar to the one from intel real sense utilizing corner points as close as possible to the image border.	5 years ago

Oleg Alexandrov	af433d0352	Merge pull request #15780 from oleg-alexandrov:master * Doc bugfix The documentation page StereoBinaryBM and StereoBinarySGBM says that it returns a disparity that is scaled multiplied by 16. This scaling must be undone before calling reprojectImageTo3D, otherwise the results are wrong. The function reprojectImageTo3D() could do this scaling internally, maybe, but at least the documentation must explain that this has to be done. * calib3d: update reprojectImageTo3D documentation * calib3d: add StereoBM/StereoSGBM into notes list	5 years ago
