Pandora: 一人称視点映像からの関節付き3Dシーングラフ構築
Pandora: Articulated 3D Scene Graphs from Egocentric Vision
人間がProject Ariaグラスを装着して探索する際の一人称視点映像から、関節付き物体のモデルを復元し、3Dシーングラフに統合する手法を提案。ロボットの操作能力に依存せず、人間の自然な探索行動を活用することで、ロボット単独では得られない環境情報を獲得できる。

原文アブストラクト
Robotic mapping systems typically approach building metric-semantic scene representations from the robot's own sensors and cameras. However, these "first person" maps inherit the robot's own limitations due to its embodiment or skillset, which may leave many aspects of the environment unexplored. For example, the robot might not be able to open drawers or access wall cabinets. In this sense, the map representation is not as complete, and requires a more capable robot to fill in the gaps. We narrow these blind spots in current methods by leveraging egocentric data captured as a human naturally explores a scene wearing Project Aria glasses, giving a way to directly transfer knowledge about articulation from the human to any deployable robot. We demonstrate that, by using simple heuristics, we can leverage egocentric data to recover models of articulate object parts, with quality comparable to those of state-of-the-art methods based on other input modalities. We also show how to integrate these models into 3D scene graph representations, leading to a better understanding of object dynamics and object-container relationships. We finally demonstrate that these articulated 3D scene graphs enhance a robot's ability to perform mobile manipulation tasks, showcasing an application where a Boston Dynamics Spot is tasked with retrieving concealed target items, given only the 3D scene graph as input.
