由模型翻译 · 术语统一 · 请对照原文核对关键结论我们提出 Coded-E2LF（编码事件到光场），一种利用编码孔径与固定式纯事件相机采集四维光场的计算成像方法。在先前的工作中，曾采用与我们类似的成像系统，但同时采集事件与强度图像并用于光场重建。相比之下，我们的方法完全基于事件，从而放宽了硬件实现的限制。我们还引入了若干相对先前工作的改进，使我们能够在理论上支持并在实践中提升仅凭事件进行光场重建的效果。特别地，我们阐明了黑色图案在孔径编码图案中的关键作用。最后，我们在真实成像硬件上实现了该方法，以展示其在采集真实三维场景方面的有效性。据我们所知，我们是首个证明可以仅凭事件重建出像素级精度的四维光场的工作。我们的软件与补充视频可在项目网站获取：https://www.fujii.nuee.nagoya-u.ac.jp/Research/EventLF/。

We propose Coded-E2LF (coded event to light field), a computational imaging method for acquiring a 4-D light field using a coded aperture and a stationary event-only camera. In a previous work, an imaging system similar to ours was adopted, but both events and intensity images were captured and used for light field reconstruction. In contrast, our method is purely event-based, which relaxes restrictions for hardware implementation. We also introduce several advancements from the previous work that enable us to theoretically support and practically improve light field reconstruction from events alone. In particular, we clarify the key role of a black pattern in aperture coding patterns. We finally implemented our method on real imaging hardware to demonstrate its effectiveness in capturing real 3-D scenes. To the best of our knowledge, we are the first to demonstrate that a 4-D light field with pixel-level accuracy can be reconstructed from events alone.
