| 摘 要： | 传统的粒子滤波即时定位与地图构建(SLAM)算法在构建地图和目标进行自主定位时,粒子数量大,占用的内存高,重采样之后容易出现粒子匮乏现象,为了提高机器人自主定位的效率,提出了一种改进的重采样策略和粒子更新策略,融入系统模型.在装有机器人操作系统(ROS)的旅行家移动机器人上进行测试,实验结果表明:方法能够有效提升粒子滤波定位的效率.

| Abstract: | The traditional particle filtering simultaneous localization and mapping (SLAM) algorithm in the construction of mapping and autonomous positioning,usually need large number of particles and take up a lot of memory,particles appear deprivation after the resampling process,in order to improve the efficiency of robot autonomous positioning,aiming at particle filtering algorithm,propose an improved resampling strategy and particle update strategy,fuse system model.By testing the algorithm on a mobile robot equipped with robot operating system (ROS),the algorithm is validated by experimental method.The experimental results show that the method can improve the efficiency of particle filtering positioning. |
