This work proposes a SLAM (Simultaneous Localization and Mapping) technique based on Extended Kalman Filter (EKF) to navigate a robot in a plane environment using odometry and pre-existing lines on the floor as landmarks. The lines are identified by using the Hough transform and are mapped to world coordinates using homography matrix. The prediction phase of the EKF is implemented using the odometry model of the robot. The update phase directly uses the parameters of the lines detected by the Hough transform without additional intermediate calculations. Experiments with real data are presented.
