Extended Kalman Filter (EKF) Simultaneous Localization and Mapping (SLAM) i a technokque used i in robotics to build a map of an unknown environment while e requaneously determing the robot 's position with inn it. A key provident of EKF- SLAM iss the covariance matrix, which repress the unconfirity ity ithis mate state state' stipis stipe stipe stipe.

Initialization of Covariance Matrix

A projekt kezdete: with initializing the covariance matrix, typically denoted ad P. Tiss matrix combines the uncerties of the robot 's pose and te map features. The initial covariance reflects the initiad confidence ite robot' s startting position and the known expecures.

Prediction Step

During the prediktion fese, the robot 's motivo' s model i used to estimate the new state. Te covariante matrix i updated using the Jacobian of the motion model, denoted as F, and the proces noise covariance, Q. The update follows:

Update Stepwith Measurements

When new sensor measuremens are receivede, the covariance matrix i s updated to included tis information. The mequurement model 's Jacobian, H, and the the mequurement noise covariance, R, are used to compute the Kalman gain, K:
