I have a IMU attached to the foot and another attached to the tibia. I want to measure individual angles about each axis(X,Y and Z) between those two sensors(using quaternion output). I have done the necessary axis remap to account for the orientation changes.
The problem is that both IMU's have an initial offset values beacue of the uneven suface of the body. And the axis of the IMU is alligned with the body bones as reference and not with each other so I cannot directly take the difference in euler angles
