| 摘 要： | 研究了基于扩展卡尔曼滤波和粒子滤波的移动机器人位姿估计。由于扩展卡尔曼滤波必须假定噪声服从高斯分布,若用于复杂非线性系统,其估计精度不甚理想。粒子滤波对噪声类型没有限制,正在成为非线性系统状态估计的有效近似方法。在不同噪声条件下,对基于粒子滤波和扩展卡尔曼滤波的移动机器人位姿估计问题进行了比较研究。仿真结果表明:粒子滤波能明显地改善移动机器人位姿估计的鲁棒性和精度。

| Abstract: | The issue of pose state estimate of mobile robots based on extended Kalman filter(EKF) and particle filter is studied.Because EKF must assume that the noise is subject to Gaussian distribution,the estimate accuracy is not so good if it is used to estimate the state of complicated nonlinear system.Particles filter(PF) has no restriction to the noise type and it is an effective approximate method for the state estimate of nonlinear systems.Under various noise conditions,the comparative studies for the pose st... |
