Abstract :
In this paper we propose a method for solving the SLAM problem for mobile robot when moving in an unknown environment. Our method takes computational advantages of the FastSLAM algorithm. To estimate the position of the robot, we use a particle filter. The weights for the set of particles that characterize the expected position of the robot, are determined by the condition number of the plane homography matrix. It can be considered as the projective mapping of points of the scene on the two-dimensional surface of camera sensor. A set of unscented Kalman filters is used to estimate the positions of detected landmarks which are forming the map of the observed environment. Methods for detecting and description of landmarks were not considered in this paper, as it is beyond the scope of this work.
