Any ideas what can I do to solve the acceleration problem and update the filter only with true tilt angles? Would you be so kind to recommend what i need to get started? These plug and play solutions include full factory calibration, embedded compensation and sensor processing, and a simple programmable interface.
If you want to calculate inclination of device relative to the ground you can calculate the angle between this vector and Z axis.
But i also want to filter my acceleration output with Kalman filter not the microcontroller friendly one.
I would like to know what do the angles Axr,Ayr and Azr as well as Axz,Ayz und Axy represent? If we are using it throughout the calculations then, what are we doing to denormalize corrected accelerations of normalized Racc? The diameter and depth of the lua will match the amount of food to be cooked.
I think, thats a method I could use, right? But i have some problems… My device need to calculate velocity and traveled path of the car.
One thing you should learn from this is that an accelerometer measures acceleration indirectly through a force that is applied to one of it's walls according to our model, it might be a spring or something else in real life accelerometers.
