E$^{3}$NeRF: Efficient Event-Enhanced Neural Radiance Fields from Blurry Images

Understand

Neural Radiance Fields (NeRF) achieves impressive novel view rendering performance by learning implicit 3D representation from sparse view images.

• However, it is difficult to reconstruct a sharp NeRF from blurry input that often occurs in the wild.
• To solve this problem, we propose a novel Efficient Event-Enhanced NeRF (E$^{3}$NeRF), reconstructing sharp NeRF by utilizing both blurry images and corresponding event streams.
• A blur rendering loss and an event rendering loss are introduced, which guide the NeRF training via modeling the physical image motion blur process and event generation process, respectively.
