camera intrinsic

Congratulations on the outstanding work presented in your paper! I am currently working on processing my own data and have encountered some challenges regarding the alignment of my mesh and the rendered Gaussian results.

Specifically, I noticed a certain offset between my results and those shown in your work. I would like to ask how you generated your camera parameters, particularly the following:
<Key: camera_matrix : [[ 4.9223537 0. -0.08888889 0. ] [ 0. 4.941477 0.05 0. ] [ 0. 0. 1.0001 -0.01010101] [ 0. 0. 1. 0. ]] Key: camera_transform : [[1. 0. 0. 0.] [0. 1. 0. 0.] [0. 0. 1. 0.] [0. 0. 0. 1.]] Key: transl : [[0.1355158 0.29134032 5.315963 ]]
My Result:
result['camera_matrix']
[[ 1.6666666 0. 0. 0. ]
[ 0. 1.6666666 0. 0. ]
[ 0. 0. 1.0002 -0.020002 ]
[ 0. 0. 1. 0. ]]
camera_transform
[[ 1. 0. 0. -0.6301099 ]
[ 0. 1. 0. -0.40954894]
[ 0. 0. 1. 3.9324636 ]
[ 0. 0. 0. 1. ]]。
I would greatly appreciate any insights or guidance you could provide regarding the generation of these camera parameters.

Thank you for your help!

Best regards,

Hi! You can find the code I used to get SMPL-X and camera parameters here: #10 (comment)
Also the discussion in this issue might be useful.

Thank you for your patient response. I ran simplify-x according to the code you shared, but I found that the loss became particularly large during the optimization process. I checked the issues in the simplify-x project, and someone mentioned that it might be a problem with the vposer version and that vposer_v1_0 is needed (which is only compatible with lower versions of torch). However, I noticed that your project uses vposer02. Could you please let me know the specific version of vposer you are using? If possible, could you share the configuration of your environment as well? Thank you very much!

I used vposer 2.2.2.0
