Looking at a binary blob I got off of the intel realsense F200 camera
I found numbers in the upper triangle matrix format typically used for
intrinsic calibration.
(A)
1.487056 0.000000 0.012773
0.000000 1.982741 0.029860
0.000000 0.000000 1.000000
This doesn't match numbers from a manual calibration I did a while
ago, and I'm trying to figure out if this is some kind of equivalent
form.
My manual calibration
(B)
475.310051 0.000000 335.282418
0.000000 474.440685 242.982056
0.000000 0.000000 1.000000
If I take the top left number from A which should be a focal length to
pixel size number, and multiply it by half the width of the image 320
I get
475.85792 = 1.487056 * 320
Which is about the size of the number in B.
Similarly if I take the middle number from A, and multiply it by half
the height of the image I get.
475.85784 = 1.982741×240
The last two significant numbers I can't make any sense of how to convert them.
0.012773 should be a number for the X center of the image
0.029860 should be the Y center.
I'm hoping someone with more experience with the math can help.
