Hello

I have problem with understanding Projection and camera matrix.

So when I calibrated camera I got my camera matrix I guess in pixels. My translate matrix which I wil use for calulating Projection matrix is in milimeters. So I am guessing I have to convert Camera matrix units into mm, is that right? I am not sure how I supposed to do it. I need this projection matrix for using triangulatePoints() and I am little off of good result so now I am searching for issues in matrix.
