Discrepancy between IK and FK in retargeting human motion to humanoids #25

Closed Maxwell-Zhao closed 1 hour ago

Maxwell-Zhao commented 9 hours ago

In the paper, the authors mention that they retarget human motions to the humanoid using inverse kinematics, but in the file grad_fit_h1_shape.py, it appears that forward kinematics is used instead of IK.

Maxwell-Zhao commented 9 hours ago

This is a FK model in file grad_fit_h1_shape.py. QQ_1733317691605

The IK is implemented based on optimization with FK.
