Introducing SAM 3D: Powerful 3D Reconstruction for Physical World Images

TL;DR

  • Announcement of SAM 3D, including SAM 3D Objects for object/scene reconstruction and SAM 3D Body for human body/shape estimation.
  • Release includes training/evaluation data, benchmarks, model checkpoints, inference code, and a parametric human model (MHR).
  • Introduction of the Segment Anything Playground for public experimentation with SAM models.
  • SAM 3D and SAM 3 are powering Facebook Marketplace's new View in Room feature.
  • SAM 3D Objects reconstructs detailed 3D shapes, textures, and layouts from single images, overcoming data limitations with a novel data annotation engine and training recipe.
  • SAM 3D Body provides accurate 3D human pose and shape estimation from single images, even in complex scenarios, using a large dataset and automated data engine.
  • Limitations for SAM 3D Objects include moderate output resolution and the need for improved object layout reasoning.
  • Limitations for SAM 3D Body include the lack of multi-person/human-object interaction reasoning and the need for further improvement in hand pose estimation.
