让机器人通过智能推物看清被遮挡的物品,大幅提速且少移动。

Efficient Manipulation-Enhanced Semantic Mapping With Uncertainty-Informed Action Selection

  • 用不确定性预测指导看哪里、推哪物,聚焦信息最少区域。
  • 相比顶尖方法,规划时间减少95%,物品挪动量显著降低。
  • 适合需要快速精准建图的家用或办公服务机器人场景。

在家庭、办公室等杂乱人机环境中,服务机器人无法依赖预设物体布局,必须持续更新语义与空间认知,并应对频繁重排。高效准确的建图需选择高信息量视角和针对性操作以减少遮挡与不确定性。本文提出一种面向遮挡密集货架场景的增强型语义建图框架,融合证据推理的度量-语义建图与基于强化学习的最优视点规划及目标动作选择。通过地图预测网络中狄利克雷(Dirichlet)与贝塔(Beta)分布的不确定性估计,引导主动传感器部署与物体操作,聚焦高不确定性区域并选择预期信息增益高的动作。进一步提出一种不确定性驱动的推物策略,针对关键遮挡物体进行最小侵入式操作,有效揭示隐藏区域,降低整体场景不确定性。实验表明,该框架可准确映射杂乱场景,显著减少物体位移,相比现有最优方法规划时间减少95%,具备实际应用潜力。

原文摘要 · Abstract (English)

Service robots operating in cluttered human environments such as homes, offices, and schools cannot rely on predefined object arrangements and must continuously update their semantic and spatial estimates while dealing with possible frequent rearrangements. Efficient and accurate mapping under such conditions demands selecting informative viewpoints and targeted manipulations to reduce occlusions and uncertainty. In this work, we present a manipulation-enhanced semantic mapping framework for occlusion-heavy shelf scenes that integrates evidential metric-semantic mapping with reinforcement-learning-based next-best view planning and targeted action selection. Our method thereby exploits uncertainty estimates from Dirichlet and Beta distributions in the map prediction networks to guide both active sensor placement and object manipulation, focusing on areas with high uncertainty and selecting actions with high expected information gain. Furthermore, we introduce an uncertainty-informed push strategy that targets occlusion-critical objects and generates minimally invasive actions to reveal hidden regions by reducing overall uncertainty in the scene. The experimental evaluation shows that our framework enables to accurately map cluttered scenes, while substantially reducing object displacement and achieving a 95% reduction in planning time compared to the state-of-the-art, thereby realizing real-world applicability.
