About camera convertion #55

Closed Jianxff closed 1 month ago

Jianxff commented 1 month ago

Hi, the reconstruction result is quite well, but I got confused with the camera convertion for render.

I want to recover real-world metric position of the hand mesh, and I find the camera convertion on cam_crop_to_full. Could you tell me some detail about the following two lines of code? I wonder What bs means and Why tz is calculated by multiplying 2.

Thanks!

Please check this issue for an explanation of how tz is calculated: https://github.com/shubham-goel/4D-Humans/issues/125#issuecomment-2142635931
