Kalman Filter is a recursive filter that tracks the linear and nonlinear states of noise, and was first proposed by R. E. Kalman in the 1960s. Here, the state is a value that varies with time, and represents a system trajectory. The Kalman filter algorithm can be applied to a model system that predicts or estimates the following states by predicting and correcting past, present, and future states.
The existing Kalman filter is an algorithm developed for a linear model. However, since the actual model has a nonlinear structure, more precise coordinate information can be obtained by applying an extended Kalman filter (EKF) in which a conventional Kalman filter is applied to a nonlinear model.
