摘要

利用卡尔曼滤波方法将无线网络信号强度数据与车辆传感器信息相结合,估计出机器人编队中各车辆的相对位置。车辆传感器包括车轮速度和转向角度,WiFi数据包括接收信号强度(RSS)和最大RSS相对于机器人方向的角度。考虑非完整非线性车辆模型的非线性特性,采用扩展卡尔曼滤波EKF。给出了该估计策略的仿真和实验结果

Wireless Reception Signal Strength for Relative Positioning in a Vehicle Robot Formation
An integration of the wireless network signal strength data with the vehicle sensors information by means of a Kalman filter is proposed to estimated the relative position of each vehicle in a robot formation set. Vehicle sensors consist of wheel speed and steering angle, the WiFi data consist of reception signal strength (RSS) and the angle of the maximal RSS with respect to the robot orientation. A nonholonomic nonlinear model vehicle is considered, due to this nonlinearities a extended Kalman filter EKF is used. Simulation and experimental results of the proposed estimation strategy are presented
