Compatibility with ZJU format

[KhanhNgoDuy]

Hi, thank you for your work.

Currently, I am training GauHuman on your dataset. I tried to reuse the Dataloader for ZJU, however the training result is always black. It seems that your dataset is using a different format with the ZJU Monocap dataset.

I only modify the data of camera translation by multiplying with camera_scale.pkl. The way I convert original data of MVHuman to ZJU format is:

1. new_params: taken from smpl/smplx.
2. new_vertices: taken from smpl_param
3. cams: taken from camera_intrinsics, camera_extrinsics
4. kpts2d: taken from openpose

Questions/notices:

1. The SMPL parameters has shape of (1, 87), while it is (1, 72) in ZJU.
2. Is the camera convention in MVHuman the same as in ZJU?
3. How can I convert the MVHuman data to the exact format of ZJU?

Thank you!
