Need to calculate rotation-vector from Sensor.TYPE_ORIENTATION data
- by Sponge
I need to calculate a rotation vector out of the data i get from Sensor.TYPE_ORIENTATION.
The sensor data is defined like this:
the values have to be recalculated to become a correct 3d position: values[0]: Azimuth, angle between the magnetic north direction and the Y axis, around the Z axis (0 to 359). 0=North, 90=East, 180=South, 270=West
values[1]: Pitch, rotation around X axis (-180 to 180), with positive values when the z-axis moves toward the y-axis.
values[2]: Roll, rotation around Y axis (-90 to 90), with positive values when the x-axis moves away from the z-axis
I need all three values like the Z axis value (from 0 to 360 degree). I tried a lot but cant figure out how to do this :/
i also tried to use Sensor.TYPE_ACCELEROMETER and Sensor.TYPE_MAGNETIC_FIELD to calculate this 3d vector on my own. here is the code:
final float[] inR = new float[16];
// load inR matrix from current sensor data:
SensorManager.getRotationMatrix(inR, null, gravityValues, geomagneticValues);
float[] orientation = new float[3];
SensorManager.getOrientation(inR, orientation);
mapMagAndAcclDataToVector(orientation); //here i do some *360 stuff
orientetionChanged(orientation); //then the correct values are passed (in theorie)
But this didn't work and i think it is much to complicated.
So i bet there is a simple solution how to recalc the values of ensor.TYPE_ORIENTATION to make them a 3d rotation vector, but i just dont know how to do it. If you know the answer please tell me.
