POSITION ESTIMATION

[RBAGU.1]

I am working with DatalogFusion application and I can see the parameters quaternion, rotation,gravity,linear_acceleration,...

Assuming the errors of this kind of measurements, Wich is the best option to estimate the 2D position for a vehicle, using these parameters?

Thanks.

Hi, it depends whether you are interested in detecting the "rotation" of the vehicle (and in this case quaternions are the most indicated), or in the position detection with respect to an initial known position, and in this case the (double) integration of the X and Y axis acceleration can be. Alternatively, you might use the absolute reference of the magnetic sensor to have an initial, known position. I suggest you to have a look to the libraries of the X-CUBE-MEMS1 package that might suggest you the best way to deal with your problem.
