Kalman filter gain calculation
WebbThe smaller the matrix values, the smaller the system noise. The Filter will become stiffer and the estimation will be delayed. The weight of the system's past will be higher compared to new measurement. Otherwise the filter will be more flexible and will react strongly on each new measurement. Now everything is ready to configure the Pykalman.

WebbThe Kalman filter was applied repeatedly until its output converged. Values of Kalman gain were fixed in angle calculation in our previous studies. Those gain values are … WebbThis chapter describes the Kalman Filter which is the most important algorithm for state estimation. The Kalman Filter was developed by Rudolf E. Kalman around 1960 [7]. There is a continuous-time version of the Kalman Filter and several discrete-time versions. (The discrete-time versions are immediately ready for implementation in a computer ...
Kalman filtering uses a system's dynamic model (e.g., physical laws of motion), known control inputs to that system, and multiple sequential measurements (such as from sensors) to form an estimate of the system's varying quantities (its state) that is better than the estimate obtained by using only one measurement alone. As such, it is a common sensor fusion and data fusion algorithm.
