EgoMe: A New Dataset and Challenge for Following Me via Egocentric View in Real World

  • 采集7902对俯视与第一视角视频,还原观察-模仿全过程。
  • 包含眼动、惯性传感器等多模态数据,揭示模仿认知机制。
  • 适合研究机器人模仿学习与人机交互的科研人员使用。

在人类模仿学习中,模仿者通常以第一视角为基准,将从外部视角观察到的行为自然迁移到自身动作中,这为机器人更有效地模仿人类行为提供了启发。然而,现有研究多聚焦于不同摄像机视角间的基础对齐问题,缺乏从模仿者视角收集的数据,与高层认知过程不一致。为此,我们引入一个大规模真实世界第一视角数据集EgoMe,旨在通过模仿者的第一视角推进人类模仿学习研究。该数据集包含7902对(共15804条)俯视-第一视角视频,覆盖多样日常行为和真实场景。每对视频中,一条记录模仿者观察示范者动作的俯视视角,另一条记录模仿者随后执行动作的第一视角。尤为关键的是,EgoMe首次融合了俯视-第一视角眼动数据、多模态传感器IMU数据及多层次标注,用于建立观察与模仿过程之间的关联。我们还提供一套挑战性基准任务,以充分挖掘该数据资源并推动机器人模仿学习研究。大量分析表明,其显著优于现有数据集。EgoMe数据集与基准任务已公开于https://huggingface.co/datasets/HeqianQiu/EgoMe。

原文摘要 · Abstract (English)

In human imitation learning, the imitator typically take the egocentric view as a benchmark, naturally transferring behaviors observed from an exocentric view to their owns, which provides inspiration for researching how robots can more effectively imitate human behavior. However, current research primarily focuses on the basic alignment issues of ego-exo data from different cameras, rather than collecting data from the imitator's perspective, which is inconsistent with the high-level cognitive process. To advance this research, we introduce a novel large-scale egocentric dataset, called EgoMe, which towards following the process of human imitation learning via the imitator's egocentric view in the real world. Our dataset includes 7902 paired exo-ego videos (totaling15804 videos) spanning diverse daily behaviors in various real-world scenarios. For each video pair, one video captures an exocentric view of the imitator observing the demonstrator's actions, while the other captures an egocentric view of the imitator subsequently following those actions. Notably, EgoMe uniquely incorporates exo-ego eye gaze, other multi-modal sensor IMU data and different-level annotations for assisting in establishing correlations between observing and imitating process. We further provide a suit of challenging benchmarks for fully leveraging this data resource and promoting the robot imitation learning research. Extensive analysis demonstrates significant advantages over existing datasets. Our EgoMe dataset and benchmarks are available at https://huggingface.co/datasets/HeqianQiu/EgoMe.
