AI总结:

EgoReveal框架从自我中心演示学习视点重定位与操作动作,通过两个模仿策略切换处理部分遮挡,实验中比固定相机基线更可靠完成任务。

摘要:

从演示学习(LfD)使机器人能直接从人类演示中学习物体操作。与资源密集且劳动密集的远程操作相比,自我中心演示易于收集,可实现可扩展的数据采集。在日常环境中,被操作物体常处于部分遮挡状态,但此前无需机器人或专用教学设备的基于自我中心演示的方法未明确处理遮挡问题。为填补这一空白,我们提出EgoReveal框架,该框架从人类自我中心演示中学习视点重定位与操作动作,以重定位视点并在部分遮挡下获得目标可见性。EgoReveal将此实例化为两个模仿策略:一个从当前视角及相机-机械臂位姿预测未来相机-机械臂位姿序列,另一个从物体关键点及控制命令历史预测未来控制命令。EgoReveal根据目标可见性在两者间切换。在被操作物体初始部分遮挡的实验中,EgoReveal重定位相机以获得可见性,且比固定相机基线更可靠地完成任务。

英文摘要:

Learning from Demonstrations (LfD) enables robots to learn object manipulation directly from human demonstrations. In contrast to resource-intensive and labor-intensive teleoperation, egocentric demonstrations are easy to collect, enabling scalable data collection. Manipulated objects are often partially occluded in everyday environments, yet prior egocentric demonstration-based methods that require no robots or specialized teaching devices do not explicitly address occlusions. To fill this gap, we propose EgoReveal, a framework that learns viewpoint-repositioning together with manipulation actions from egocentric human demonstrations to reposition the viewpoint and obtain target visibility under partial occlusions. EgoReveal instantiates this as two imitation policies: one predicts the future camera-arm pose sequence from the current view and camera-arm pose, and the other predicts the future control commands from object keypoints and a history of control commands. EgoReveal switches between the two based on target visibility. In experiments where the manipulated object is partially occluded initially, EgoReveal repositions the camera to obtain visibility and completes the task more reliably than fixed-camera baselines.
