Unit of pose vectors from solvePnP()

edit

By looking at the output, I received something like "Translation: -224.111 -494.222 781.111", each for case in X, Y and Z. But, why is it too high if I would interpret in meters for example. If it's in mm, it makes a little bit sense. Also, why do you actually mean by "depends on the unit of the 3D points you us", I just define some 3D points that is nothing to do with actual unit of measurement?

Can you paste your code and the data that you are using? because I don't understand your doubt or what is the problem.

But, I think the translation that outputted from solvePnP() is in pixel unit.
