EF-3DGS: Event-Aided Free-Trajectory 3D Gaussian Splatting

Understand

Scene reconstruction from casually captured videos has wide applications in real-world scenarios.

• With recent advancements in differentiable rendering techniques, several methods have attempted to simultaneously optimize scene representations (NeRF or 3DGS) and camera poses.
• Despite recent progress, existing methods relying on traditional camera input tend to fail in high-speed (or equivalently low-frame-rate) scenarios.
• Event cameras, inspired by biological vision, record pixel-wise intensity changes asynchronously with high temporal resolution, providing valuable scene and motion information in blind inter-frame intervals.
