Assertion failure durring defishing in initUndistortRectifyMap
I'm trying to do fish an image by providing "camera_matrix" and "distortion_coefficients" to cv::fisheye::undistortImage. problem is I'm getting Assertion error. Reason is the distortion coefficients which i'm getting through camera calibration are 5x1
<distortion_coefficients type_id="opencv-matrix">
<rows>5</rows>
<cols>1</cols>
<dt>d</dt>
<data>
-2.0834245161331000e-01 5.8179563841609050e-02 0. 0.
-8.0440183287724919e-03</data></distortion_coefficients>
but undistortImage method accepts 4X1 distortion matrix. Any idea whats the way around to this problem
Following is the error which I'm getting
'error: (-215) K.size() == Size(3, 3) && (D.empty() || D.total() == 4) in function initUndistortRectifyMap'
how did you achieve those dist coeffs ?
(my guess is, you have to use a fisheye calibration as well, not the ordinary one.)
I used "opencv/samples/cpp/tutorial_code/calib3d/camera_calibration/camera_calibration.cpp" script.
try to enable it here: https://github.com/opencv/opencv/blob...
It worked like a charm. Can you write it as an answer so then i can mark it. One more thing. After applying the distortion I'm loosing some of the image (Is there a way to avoid that).
"loosing some of the images" - means ?
origional
undistorted
I was acceding my comment limit so i had to divide it in two. If you see I'm loosing some of the image in undistorted version. Any idea how to avoid it.
^^ url fail.
