New framework generates articulated object models from casual videos

Researchers have developed a new framework to reconstruct articulated objects and hand-object interactions from casual monocular RGB videos. This method, called Track, Articulate, Act, does not require depth sensors, multiple views, pre-defined joints, or robot demonstrations. It leverages dense 3D point tracks to infer articulation by segmenting links and estimating joint trajectories, then reconstructs an articulated asset and aligns hand motion for simulation in MuJoCo. The approach effectively repurposes pretrained vision models for 3D reconstruction and scene flow, enabling the creation of simulation-ready articulated object models from everyday videos for downstream embodied AI tasks.
