RayViT enhances robot imitation learning with camera geometry

Researchers have developed RayViT, a novel architecture that enhances visual imitation learning for robots by incorporating camera geometry into Vision Transformer models. This approach injects explicit geometric cues, represented as Plücker ray maps, into pretrained ViT backbones. Experiments show that RayViT significantly improves robustness to camera perturbations, achieving a 13 percentage point gain on the RoboCasa benchmark and a 1.78 average completed stages improvement in real-world tasks.
