2D Detection Transformers Show Surprising 3D Understanding

Researchers have investigated the 3D object-level understanding capabilities of pre-trained 2D detection transformers, such as DETR. Their findings indicate that these models, despite being trained solely on 2D data without explicit 3D supervision, possess a significant ability to represent information about object depth and 3D location relative to the camera. This suggests a previously unrecognized capacity within these models for inferring 3D properties from 2D embeddings. AI

IMPACT Reveals an unexpected capability in 2D vision models to infer 3D information, potentially impacting future model architectures and training strategies.
