摘要:

辅助机器人在物体整理方面的应用前景一直备受关注。在图像目标设定下,机器人需要重新布置当前场景,使其与目标场景中拍摄的单张图像相匹配。图像目标重排系统的关键在于基于单张目标图像和对当前场景的观测来估计每个物体期望的放置位姿。为了建立足够的关联以实现准确估计,系统应从与目标图像中相似的视角观察物体。现有的图像目标重排系统由于依赖固定视角进行感知,往往需要冗余的操作来随机调整物体位姿以获得更好的观察视角。针对这一低效问题,我们提出了一种采用多视角融合的新型物体重排系统。通过在操作物体之前从多个视角观察当前场景,我们的方法能够在无需冗余操作次数的情况下估计出更准确的位姿。我们开发了一个物体级别的标准视觉定位流程,以充分利用多视角观测的优势。仿真结果表明,我们系统的效率优于现有的单视角系统。该系统的有效性还在物理实验中得到了进一步验证。

英文摘要:

The prospect of assistive robots aiding in object organization has always been compelling. In an image-goal setting, the robot rearranges the current scene to match the single image captured from the goal scene. The key to an image-goal rearrangement system is estimating the desired placement pose of each object based on the single goal image and observations from the current scene. In order to establish sufficient associations for accurate estimation, the system should observe an object from a viewpoint similar to that in the goal image. Existing image-goal rearrangement systems, due to their reliance on a fixed viewpoint for perception, often require redundant manipulations to randomly adjust an object's pose for a better perspective. Addressing this inefficiency, we introduce a novel object rearrangement system that employs multi-view fusion. By observing the current scene from multiple viewpoints before manipulating objects, our approach can estimate a more accurate pose without redundant manipulation times. A standard visual localization pipeline at the object level is developed to capitalize on the advantages of multi-view observations. Simulation results demonstrate that the efficiency of our system outperforms existing single-view systems. The effectiveness of our system is further validated in a physical experiment.
