论文摘要
现代高动态范围（HDR）成像管道在不同的曝光时间捕获的多个低动态范围（LDR）图像对齐和融合。尽管这些方法在静态场景中效果很好，但动态场景仍然是一个挑战，因为LDR图像仍然遭受饱和和噪声的影响。在这种情况下，由于其更高的时间分辨率和动态范围，事件摄像机将是有效的补充。在本文中，我们提出了第一个多支架HDR管道，将标准摄像头与事件摄像头结合在一起。我们的结果在使用事件时表现出更好的总体鲁棒性，在合成数据上最多可改善PSNR，最多可在实际数据上进行0.7dB。我们还介绍了一个新的数据集，其中包含包含包围的LDR图像，这些图像具有对齐事件和HDR地面真相。
Modern high dynamic range (HDR) imaging pipelines align and fuse multiple low dynamic range (LDR) images captured at different exposure times. While these methods work well in static scenes, dynamic scenes remain a challenge since the LDR images still suffer from saturation and noise. In such scenarios, event cameras would be a valid complement, thanks to their higher temporal resolution and dynamic range. In this paper, we propose the first multi-bracket HDR pipeline combining a standard camera with an event camera. Our results show better overall robustness when using events, with improvements in PSNR by up to 5dB on synthetic data and up to 0.7dB on real-world data. We also introduce a new dataset containing bracketed LDR images with aligned events and HDR ground truth.
