I just found this thread. You are going so fast with your building process that I almost missed it!
It's great to see everything went smoothly, I can't wait to see the full body capture!
Going back to some of your questions and observations:
highmatergogo How does this system cope with magnetic disturbances? I know that's been an issue with the Neuron Perception kit.
The chordata system is based on inertial and magnetic sensors just as the perception neuron.
This type of capture is inherently susceptible to magnetic disturbances, but there seems to be spread concern about that particular suit being susceptible to magnetic disturbances. In our experience a strong magnetic disturbance at a short distance is required to influence the capture. For example you start sensing the influence of a big speaker at around 1 meter, and a laptop at around 70 cm.
More expensive suits implement algorithmic corrections in order to achieve better stability in the presence of magnetic disturbances. Chordata currently use the widely spread Madgwick's algorithm for the sensor fusion which is not aware of the magnetic disturbances. But there is plenty of scientific literature on this subject so we should be able to implement different algorithms once we end the prototypical stage.
highmatergogo How is foot to floor stability in the output animation?
Do you mean feet slip in translation?
translation in inertial capture is derived from the other measurements. Chordata currently doesn't implement an algorithm to obtain translation in space.
We are currently focusing our development efforts on usability, stability and documentation. The idea is: if the codebase is consolidated and well documented, and the overall system is easy to use improvements like these might start coming from the community. Our main goal is to provide a solid framework where to build a better mocap system all together.
highmatergogo So this is basically becoming a build thread 😂 Hope that's OK!?
That's great! and by the way: thanks for sharing your experience so meticulously. That's the kind of spirit that pushes projects like this one forward.
