Summary
- What is new: BirdNeRF introduces a novel bird-view pose-based spatial decomposition algorithm for large-scale scene reconstruction using aerial imagery, significantly improving rendering speed and scalability.
- Why this is important: Existing NeRF solutions struggle with slow training, high computational demands, and low visual fidelity in large-scale reconstructions.
- What the research proposes: BirdNeRF uses spatial decomposition to manage large datasets by training smaller, overlapping NeRF models and employs a projection-guided re-rendering strategy for superior visual output.
- Results: Achieved a 10x speed improvement over traditional photogrammetry and 50x over existing large-scale NeRF solutions with comparable visual quality on a single GPU.
