Localization

Unscented Kalman Filter localization

2

This is a sensor fusion localization with Unscented Kalman Filter(UKF).

The lines and points are same meaning of the EKF simulation.

  3

  This is a sensor fusion localization with Particle Filter(PF).

  The blue line is true trajectory, the black line is dead reckoning trajectory,

  and the red line is estimated trajectory with PF.

  It is assumed that the robot can measure a distance from landmarks (RFID).

  This measurements are used for PF localization.

    4

    This is a 2D localization example with Histogram filter.

    The red cross is true position, black points are RFID positions.

    The blue grid shows a position probability of histogram filter.

    In this simulation, x,y are unknown, yaw is known.

    The filter integrates speed input and range observations from RFID for localization.

    Initial position is not needed.
