Mesh-based Dynamics with Occlusion Reasoning for Cloth Manipulation

Open access
Huang, Zixuan, Lin, Xingyu, Held, David·2022·Robotics: Science and Systems XVIII

Abstract

Self-occlusion is challenging for cloth manipulation, as it makes it difficult to estimate the full state of the cloth.Ideally, a robot trying to unfold a crumpled or folded cloth should be able to reason about the cloth's occluded regions.We leverage recent advances in pose estimation for cloth to build a system that uses explicit occlusion reasoning to unfold a crumpled cloth.Specifically, we first learn a model to reconstruct the mesh of the cloth.However, the model will likely have errors due to the complexities of the cloth configurations and due to ambiguities from occlusions.Our main insight is that we can further refine the predicted reconstruction by performing test-time finetuning with self-supervised losses.The obtained reconstructed mesh allows us to use a mesh-based dynamics model for planning while reasoning about occlusions.We evaluate our system both on cloth flattening as well as on cloth canonicalization, in which the objective is to manipulate the cloth into a canonical pose.Our experiments show that our method significantly outperforms prior methods that do not explicitly account for occlusions or perform test-time optimization.Videos and visualizations can be found on our project website.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
