I'm working with some imu,there is something keep stuck in my head..
We all know accelerometer and gyroscope.
Gyroscope gives you angular velocity,
Accelerometer gives you acceleration.
Then if you Integrate angular velocity gives you angle,
Integrate acceleration gives velocity,Integrate velocity gives you position.
My point is,if i want precise position or velocity from accelerometer,
I need higher sample rate to get more acceleration information?
No problem with Integrate Gyroscope,because it directly give me velocity,
and its result of integration is correct enough.
Really hope someone can answer that
