About Assumption of Focal length about img2pose HOT 1 CLOSED

The training labels were calculated using f = w_bb + h_bb, so we use that when converting to global pose, as the pose is relative to that bbox size.
You can convert the poses to other focal length simply by converting from local to global, and then converting back to your new bbox with f = w_bb, h_bb + 1.
Or you can modify our code to instead of converting from local to global, converting from local to another bigger/small local version.

Hope this helps.
