how to use Accelerometer raw data to Estimate Position and Velocity
I used MMR from mbientlab, I have 3D raw Accelerometer data (in g).
1. I need to find the velocity and position from it using Matlab. I used the integration once and twice but I'm not quite sure with the results. I guess I missed something like DC offset, increasing the error due to integration, etc.?
2. Do I need to filter the data at some stages?
