I am running stereo calibrate on a dual camera setup. I get the T and R mats back, and I need to pass the baseline distance between the cameras into my stereo vision application. This should be the T values, is that correct?

The issue is, my baseline is around 23 cm, and the T Mat is:

  <data>

Am I looking at the wrong values? Or do i need to convert this somehow?

Thanks.

Ah, the error was in my failure to understand floats. :)

As here:

2.2127166167184534e+01 7.9245638499041940e-02 1.6681677038420595e+00

equates to:

22.1, 0.07, 1.6

This is given in the same units that you use for the square size variable in StereoCalibrate.
