The fusion filter uses an extended Kalman filter to track orientation (as a quaternion), velocity, position, sensor biases, and … WebExtended Kalman filter • extended Kalman filter (EKF) is heuristic for nonlinear filtering problem • often works well (when tuned properly), but sometimes not • widely used in practice • based on – linearizing dynamics and output functions at current estimate – propagating an approximation of the conditional expectation and ...

Kalman Filter for 6DOF IMU Implementation (1/6) - YouTube

WebSep 29, 2011 · As Foxlin proposed, the use of a complementary Extended Kalman Filter (EKF) and a foot-mounted IMU has many benefits in PDR. For example, step detection is more reliable, and it is possible to apply Zero Velocity Update corrections (ZUPT) every time the foot is motion-less on the floor while walking (stance phase).
