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). WebBasics of multisensor Kalman Filtering are exposed in section 2. Section 3 introduces contextual information as a way to de ne validity domains of the sensors and so to increase reliability. A basic development of the multisensor KF using contextual information is made in section 4 with two sensors, a GPS and an IMU.
