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 ... 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.

The nonlinear discrete-time state-space model was typically formulated in the SLAM problem with Gaussian noise. The most popular filter implemented for SLAM is extended Kalman filter (EKF)[2].
