3D-DST-models

As part of our data release in 3D-DST, we present aligned CAD models for all 1000 classes in ImageNet-1k.

See wufeim/DST3D for synthetic data generation with 3D annotations using the CAD models here.

Besides the .csv file as visualized in the dataset viewer above, we also provide a python script (models_3d_dst.py) to help integrate with other Python modules.

Fields

For each CAD model, there are seven fields:

  • synset: synset associated with each ImageNet-1k class.
  • model: model ID from ShapeNet, Objaverse, or OmniObject3D
  • distance: corrected distance -- our rendering code normalize object sizes automatically, correct the rendering distance if the normalization fails
  • azimuth and elevation: viewpoint parameters used to align the canonical pose of all CAD models
  • strength: 1 if the current CAD model is good; 2 if the current CAD model only approximates the current synset
  • sampling: one of the four sampling strategies here:
    • 1: viewing from all azimuth angles, and all elevation angles, e.g., airliner
    • 2: viewing from front azimuth angles, and all elevation angles, e.g., microwave, washing machine
    • 3: viewing from all azimuth angles, and only elevation angles when viewing from up to down, e.g., keyboard, bath tub, car, beach wagon
    • 4: viewing from front azimuth angles, and only elevation angles when viewing from up to down, e.g., printer, stove
