pose_rawpoints to an array of 7 floats, describing the rotation (quaternion) and translation of the pose in the same order as the first 7 elements of the AndroidSensor.TYPE_POSE_6DOFvalues documented onSensorEvent.values().
The order of the values is: qx, qy, qz, qw, tx, ty, tz.
Ifpose_rawisNULL, initializes with the identity pose.
