Converting the acceleration data from the sensor (MetaMotion R) frame to Earth frame of reference
I am using Metamotion R sensors to get the linear accelerations. First of all I tried to stream both of the linear acceleration and the Euler angles, but the MetaBase application for iOS gave me an error that the sensors cannot stream both of them. I tried to use the data from the accelerometer and the gyroscope and I have a question about this option
1) If the approach of the integrating the gyroscope data with respect to time to get the instantaneous Euler angles and then getting the acceleration in Earth frame of reference by multiplying the inverse of Euler rotation matrix with the acceleration data is right . Then, which rotation matrix convention shall I use? Is it 'XYZ', 'ZYZ', or 'ZYX'?
Another thing, when I tried the MetaBase application for windows, I did not show me the error of measuring linear acceleration and Euler angles data simultaneously but another problem I found is that I cannot stream from more than two devices. Is there a way to overcome the problems of the MetaBase applications for windows and iOS?
Thanks in advance.
