I have a ZED camera, and I’m using the body tracking functions. Now, I would like to compute the joint angles of some limbs, such as the hip, knee and ankle during walking. I do not know if there is already a function for that. Besides, are local orientations provided for all points correct? Or some ones are still missing (I read something in another post).
You can directly access each joint’s local rotation by activating the “body fitting” option in the API (https://www.stereolabs.com/docs/body-tracking#3d-body-fitting).
When using the Body34 model, some rotations are missing due to limitations of the model. However, all the rotations are available with the Body 38 model (except for the endpoints such as fingers or toes.
