Abstract

Mobile robot localization is a complex task, specially in unstructured indoor environments, due to noise and wrong data association from sensors. The localization procedure is even harder when the vehicle has low confidence about its last pose estimate, situation that requires a Global Localization procedure. In this work, a Global Localization algorithm based on Particle Swarm Optimization (PSO) is integrated with a Pose Tracking algorithm, the Perfect Match, to obtain a robust localization technique. Results show that this approach can solve the problem of Global Localization with good performance.

基于二维激光传感器的移动机器人粒子群定位
由于来自传感器的噪声和错误的数据关联,移动机器人定位是一项复杂的任务,特别是在非结构化的室内环境中。当车辆对其最后姿态估计的置信度较低时,定位过程更加困难,这种情况需要全局定位过程。本文将基于粒子群优化(PSO)的全局定位算法与姿态跟踪算法完美匹配相结合,获得鲁棒定位技术。结果表明,该方法能较好地解决全局定位问题。
