Markov and Gaussian Localization

Mobile Robot Localization: Markov and Gaussian

Mobile robot localilzation is the problem of determining the pose of a robot relative to a given map of the environment. It is also refered to as position estimation.

Markov Localization

Probabilistic localization algorithms are variants of the Bayes filter. Markov localization is just a different name for the Bayes filter applied to the mobile robot localization problem.
