基于粒子滤波和蒙特卡罗树搜索的有源声源跟踪

Active Acoustic Source Tracking Exploiting Particle Filtering and Monte Carlo Tree Search

Thomas Haubner, Alexander Schmidt, Walter Kellermann

摘要:

在本文中,我们解决了主动声源跟踪的机器人路径规划的一部分的任务。它表示规划机器人运动序列以增强声源的跟踪结果,例如,会说话的人类,通过融合来自多个位置的观察。从本质上讲,有两种策略是可能的:短期规划,这会导致贪婪的行为,长期规划,这会考虑机器人和源的一系列可能的未来运动。在这里,我们专注于第二种方法,因为它可能会提高跟踪性能相比,贪婪的行为,并提出了一个灵活的路径规划算法,利用蒙特卡洛树搜索(MCTS)和粒子滤波的基础上,奖励信息理论的考虑。

英文摘要:

In this paper, we address the task of active acoustic source tracking as part of robotic path planning. It denotes the planning of sequences of robotic movements to enhance tracking results of acoustic sources, e.g., talking humans, by fusing observations from multiple positions. Essentially, two strategies are possible: short-term planning, which results in greedy behavior, and long-term planning, which considers a sequence of possible future movements of the robot and the source. Here, we focus on the second method as it might improve tracking performance compared to greedy behavior and propose a flexible path planning algorithm which exploits Monte Carlo Tree Search (MCTS) and particle filtering based on a reward motivated by information-theoretic considerations.
