服装操作因其多样性和变形特性而面临重大挑战,尽管人类能够轻松处理服装。现有研究未能有效复制这种灵巧性,主要受限于缺乏真实的服装操作模拟。为此,本文提出DexGarmentLab,这是首个专为灵巧(尤其是双手)服装操作设计的环境,提供15种任务场景的大规模高质量3D资产,并改进了服装建模的仿真技术,以缩小仿真与现实之间的差距。我们利用服装结构对应关系,通过单一专家演示自动生成多样化轨迹数据集,显著减少人工干预。同时,提出的分层服装操作策略(HALO)能够识别可转移的操作点,生成通用轨迹以完成任务。实验表明,HALO在处理未见实例时表现优异,成功应对形状和变形的显著变化。

📄 摘要(原文)
Garment manipulation is a critical challenge due to the diversity in garment categories, geometries, and deformations. Despite this, humans can effortlessly handle garments, thanks to the dexterity of our hands. However, existing research in the field has struggled to replicate this level of dexterity, primarily hindered by the lack of realistic simulations of dexterous garment manipulation. Therefore, we propose DexGarmentLab, the first environment specifically designed for dexterous (especially bimanual) garment manipulation, which features large-scale high-quality 3D assets for 15 task scenarios, and refines simulation techniques tailored for garment modeling to reduce the sim-to-real gap. Previous data collection typically relies on teleoperation or training expert reinforcement learning (RL) policies, which are labor-intensive and inefficient. In this paper, we leverage garment structural correspondence to automatically generate a dataset with diverse trajectories using only a single expert demonstration, significantly reducing manual intervention. However, even extensive demonstrations cannot cover the infinite states of garments, which necessitates the exploration of new algorithms. To improve generalization across diverse garment shapes and deformations, we propose a Hierarchical gArment-manipuLation pOlicy (HALO). It first identifies transferable affordance points to accurately locate the manipulation area, then generates generalizable trajectories to complete the task. Through extensive experiments and detailed analysis of our method and baseline, we demonstrate that HALO consistently outperforms existing methods, successfully generalizing to previously unseen instances even with significant variations in shape and deformation where others fail.
