Hi all,
I'm doing camera calibration using OpenCV's tutorial code from here.
As we know, the output camera matrix should in the following matrix:
[fx, 0, cx
0, fy, cy
0, 0, 1]
From that, the camera intrinsic matrix I got always has the same fx and fy. For example:
data:
[ 6.5746697810243404e+002, 0., 1560, 0.,
6.5746697810243404e+002, 1232, 0., 0., 1. ]
From the sample given by OpenCV, it also has the same fx and fy.
I don't understand why the calculated fx and fy will be the same, since the resolution for x and y is different, the sensor width and height is also different.
Is there anybody can explain this for me???
Thanks a lot.
