I'm using PARE to extract SMPL data from a reference video. PARE uses weak camera perspective, I want to render the exact perspective of the original video using the SMPL data.
FROM PARE documentation - https://github.com/mkocabas/PARE
pred_cam (n_frames, 3) # weak perspective camera parameters in cropped image space (s,tx,ty)
orig_cam (n_frames, 4) # weak perspective camera parameters in original image space (sx,sy,tx,ty)
How can I convert this into pytorch3d camera? I tried for many hours/days but the camera is always incorrect.
Ref video frame 1920x1080
Any code references you can point me to? This is the last hurdle I'm facing!
