Query: Common Objects in 3D: Large-Scale Learning and Evaluation of Real-life
  3D Category Reconstruction   Traditional approaches for learning 3D object categories have been
predominantly trained and evaluated on synthetic datasets due to the
unavailability of real 3D-annotated category-centric data. Our main goal is to
facilitate advances in this field by collecting real-world data in a magnitude
similar to the existing synthetic counterparts. The principal contribution of
this work is thus a large-scale dataset, called Common Objects in 3D, with real
multi-view images of object categories annotated with camera poses and ground
truth 3D point clouds. The dataset contains a total of 1.5 million frames from
nearly 19,000 videos capturing objects from 50 MS-COCO categories and, as such,
it is significantly larger than alternatives both in terms of the number of
categories and objects. We exploit this new dataset to conduct one of the first
large-scale "in-the-wild" evaluations of several new-view-synthesis and
category-centric 3D reconstruction methods. Finally, we contribute NerFormer -
a novel neural rendering method that leverages the powerful Transformer to
reconstruct an object given a small number of its views. The CO3D dataset is
available at https://github.com/facebookresearch/co3d .
