how to get mano pose parameter?

[abcliguanxi]

hi,thks for your great work. i have a question about the mano parameter. can we calculater the pose parameter if we have got the 21 hand joints 3D coordinates?

Hi @abcliguanxi, yes, you need to do this in an optimization step by minimizing the loss between the given points and mano joints. I have a plan to release this with some other useful tools in the future.

@otaheri when will it be released?

Hi @otaheri, thanks for your great work. Is there any progress on the optimization tool mentioned above?

It would be great ot have an official code that optimizes 21 hand joints to get the mano parameter. Looking forward to your code release. Or could you point to any existing code that does a similar thing?

I find some repos may be useful for this:
