Hello there,
I was using this demo to calibrating my own camera while the result showed a unacceptable drifts from the truth.
OpenCV version 3.2.0
Python version 3.6.7
The input images series is like below:
and the corresponding detected images is
There is one problem I am not that sure is, the asymmetric calibration target I used has a differently distance between the columns and rows which could be seen clearly from my code
longerCalibrate.txt
Finally, the result of intrinsic calibration is
camera_matrix:
but actually, the intrinsic matrix should be
9.543190920000000000e+02 0.000000000000000000e+00 6.399660030000000000e+02 0.000000000000000000e+00 9.543190920000000000e+02 3.634058530000000000e+02 0.000000000000000000e+00 0.000000000000000000e+00 1.000000000000000000e+00
this is true because the resolution of these pictures is 1280x720, more reasonable
So the question is, is there anything wrong with my code or is it a kernel problem of the opencv function?
Hi,
I tried your project and it is interesting. But I find this error:
OpenCV Error: Assertion failed ((K.depth() == CV_32F || K.depth() == CV_64F) && (D.depth() == CV_32F || D.depth() == CV_64F))
Do you know any solution to fix it?
Thanks,
Gergely
