仅用事件相机和编码光圈，实现像素级精度的4维光场重建。
Coded-E2LF: Coded Aperture Light Field Imaging from Events
- 利用编码光圈与纯事件信号进行光场成像。
- 首次实现仅靠事件数据重建4维光场，精度达像素级。
- 适用于低功耗、高动态范围的实时三维成像场景。
我们提出Coded-E2LF（编码事件到光场），一种基于编码光圈和静止事件相机的4维光场计算成像方法。以往工作同时依赖事件与强度图像进行光场重建，而本方法完全基于事件信号，降低硬件实现难度。我们引入多项改进，理论上支持并实际提升了仅从事件中重建光场的性能。特别地，阐明了光圈编码中黑色图案的关键作用。我们在真实硬件上实现了该方法，成功捕捉真实三维场景。据我们所知，这是首个仅凭事件数据实现像素级精度4维光场重建的工作。相关软件与补充视频可从项目网站获取。
原文摘要 · Abstract (English)
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. Our software and supplementary video are available from our project website.
