How to use DCM output #36

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
I am using arduimu for gesture recognition, I am a little confuse how to read 
meaning of the output (9 values)?I mean how is the interpretation of value 1-9.

I am trying to understand how can I obtain the same measurements for x,y,x in 
earth coordinates and not sensor coordinates, for example a simple up-down 
movement with the sensor place in a flat position and the same up-down movement 
with the sensor rotated 90 degrees. 

How can I make a relation between acceleration and gyro information to consider 
in either of the mentioned cases (flat or rotated) the same acceleration values 
in z (up-down)? for this I am trying to use DCM.

Any comment will be very useful, thanks
