How to calculate 3d keypoint coordinate to SMPL pose parameters?

MikoyChinese opened this issue 4 years ago · comments

Hi,
Can you tell me how to calculate 3d keypoint to smpl pose parameters, which is axis-angle. I try some way to solve it, but I can get the right pose what I want. Please help me. Thx.

I hope this repo is helpful to you. You can also further investigate the concept "inverse kinematics".

Thank you, I will try it.

Hi,
I have checked your repo, But I just found that it inputs a random pose to this model and fit it then return a mesh. I have no found about input 3d coordinate to get smpl pose parameters.

And for the inverse kinematics, I want to know the default coordinate about the original smpl model. If you have any idea about it, please help me. Thank you very much.

Have a good day!
