Parameters
- cameraMatrix
- Type: SystemDouble
Input camera matrix. - distCoeffs
- Type: SystemDouble
Input vector of distortion coefficients (k_1, k_2, p_1, p_2[, k_3[, k_4, k_5, k_6]]) of 4, 5, or 8 elements.
If the array is null, the zero distortion coefficients are assumed. - imageSize
- Type: OpenCvSharpSize
Original image size. - alpha
- Type: SystemDouble
Free scaling parameter between 0 (when all the pixels in the undistorted image are valid)
and 1 (when all the source image pixels are retained in the undistorted image). - newImgSize
- Type: OpenCvSharpSize
Image size after rectification. By default,it is set to imageSize . - validPixROI
- Type: OpenCvSharpRect
Optional output rectangle that outlines all-good-pixels region in the undistorted image. See roi1, roi2 description in stereoRectify() . - centerPrincipalPoint (Optional)
- Type: SystemBoolean
Optional flag that indicates whether in the new camera matrix the principal point
should be at the image center or not. By default, the principal point is chosen to best fit a
subset of the source image (determined by alpha) to the corrected image.
Return Value
Type:
Doubleoptimal new camera matrix
