This project will help you understand on how to intuitively develop a sensor fusion algorithm using linear kalman filter that estimates Roll, Pitch and Yaw of the vehicle with accelerometer, gyroscope and magnetometer as sensor inputs. The sensor data is used from a smartphone using MATLAB Support Package for Android Sensors. Realtime sensor fusion is also possible using this algorithm.
