To synthesize high-fidelity novel views and depth maps for unbounded real-world scenes where cameras rotate 360 degrees around a central point.
Extended the mip-NeRF anti-aliasing framework using non-linear scene parameterization to handle coordinate scaling across unbounded space.
Incorporated online distillation and a novel distortion-based regularizer to accelerate training and reduce reconstruction artifacts.
Reduced mean-squared error by 57% relative to mip-NeRF across unbounded real-world test scenes.
Produced photorealistic synthesized novel views and detailed depth maps for complex environments.

Barron et al. (2022) studied this question.
