Abstract :
This paper presents a person localization and tracking method for a leader following UGV by wireless sensors. One of the sensors is carried by the leading person as a responsive node. The others are fixed on the vehicle as anchor nodes to provide distance information about the responsive node. On the basis of these information, we can compute the position of the person by Least-Square. Installation position of the sensors on the vehicle is also discussed and optimized to reduce localization error. Combined with an Extended Kalman filter, the position of the person is estimated real-timely. The experimental results have showed the validity of this method. Our UGV can follow the leading person stably by the position estimated.
