Key IMU Data Fusion Algorithms
- Kalman Filters (EKF/UKF): The standard for optimal state estimation, using a prediction-update loop to handle noisy measurements and model complex system behavior.
- Complementary Filters: A computationally efficient approach often used in real-time systems, combining high-pass filtered gyroscopes with low-pass filtered accelerometers to achieve stable orientation estimates.
- Madgwick & Mahony Algorithms: Fast, quaternion-based filters optimized for low-power microcontrollers, delivering efficient 6 or 9-axis sensor fusion.
- Machine Learning (LSTM Networks): Deep learning methods, specifically Long Short-Term Memory (LSTM) networks, are emerging to learn complex, nonlinear dependencies in raw IMU data for improved, adaptive tracking.
- Robust Fusion (H∞ Filtering): Used to handle uncertainties and non-Gaussian noise in GNSS/IMU systems for increased reliability.
