Inverse Kinematics

Post by Ali Forouzanfar » Sun May 19, 2024 2:22 am

Hi everyone,

I am currently working on a project using OpenSim and facing a challenge with the inverse kinematics (IK) output. OpenSim's IK results provide relative anatomical angles, but for my research, I need to compare these results with my IMU data, which consists of absolute segment angles.

Has anyone dealt with a similar issue? Can someone guide me on how to convert the relative anatomical angles from OpenSim to absolute segment angles? Any scripts, references, or tips would be highly appreciated.

Thank you!
