WebJul 27, 2024 · 1. Kalman filters are just an intelligent way to do a weighted average of two measurements. Intelligent in the sense that it takes into account the uncertainties of each measurement to output the estimate with the minimum variance. In fact, if the measurement and process covariances are not changing during operation, the KF converges to a fixed ... WebApr 11, 2024 · So all you need to do is setup your implementation to accept both encoder and IMU data. This is basically a matter of providing different versions of the observation model matrix H that converts states to sensor measurements, one for each sensor. It's often the case that each sensor captures a different subset of the full state.
