Augmentron: Scalable Multi-View Visual Augmentation for Robot Learning
記録されたカメラポーズを用いて幾何学的に一貫したシーン表現を生成・描画し、時間的・多視点的一貫性を保ちながら環境や作業空間のバリエーションを拡張するパイプラインを提案。実世界データの半分を置き換えることで、分布外の妨害物体や作業空間変化に対するロボットポリシーの汎化性能が向上した。

Robot policies trained on visually narrow demonstrations can become sensitive to environmental features that are unrelated to the task. Existing generative augmentation methods can introduce visual diversity, but processing every frame and camera view independently is computationally expensive and may produce inconsistent observations across cameras and timestamps. We introduce Augmentron, a geometry-aware pipeline that generates reusable scene representations and renders them through recorded camera poses. This produces temporally and multi-view consistent environ- ment and workspace variations while preserving the robot, task objects, actions, and annotations. Across three physical manipulation tasks, replacing half of the real world training dataset with Augmentron data improves model success across three tasks for both in out-of-distribution distractor objects, and out-of-distribution workspace variation evaluations. In a separate comparison against alternate augmentation techniques, Augmentron achieves the highest pooled success in all three conditions. The results show that introducing augmented data to a data training recipe can help policies generalize to dynamic real-world settings.
