Hello, I getting a real time information from 9DoF IMU sensor (gyro, magnetometer and accelerometer), and I'm using a well known function "MahonyQuaternionUpdate" to get the Quaternion coordination: q0, q1, q2 and q4. I know how to translate the Quaternion coordination to euler angles (pitch, yaw and roll), and plot by then the orientation of the object in 3D. My problem is that pitch, yaw and roll are has limited range of angels. pitch- from -90 to 90,and once you get angel over 90, the angel start to reduce to 0. roll- from -180 to 180, and it's working fine. Yaw- I think that is the same as pitch. I read that this limited range situation is due to problem called gimbal lock, and I understood that if I will not translate the Quaternion coordination to euler angles, I can get full orientation of the body in 3-D.
Therefore, My question is how I can plot orientation in 3-D using quaternion without losing the full orientation that I lost using euler angles. thank you.
