Abstract

Bio-inspired sensors known as event cameras offer significant advantages over traditional frame-based RGB cameras, particularly in overcoming challenges like static backgrounds, overexposure, and data redundancy. In this paper, we explore the potential of event cameras in flame detection. Firstly, we establish an open-access Flame Detection dataset based on Event Cameras (FlaDE). To mitigate noise in extreme conditions with event cameras, we then propose a denoising preprocessing module termed Recursive Event Denoiser (RED). By leveraging distinctive probability distributions between signals and noise, RED achieves 0.974 (MESR) on the E-MLB benchmark, outperforming than other statistical denoising methods. Furthermore, we delve into the physical meaning behind the event rates, enabling statistical extraction of flame amidst static background and other dynamic sources. Based on this insight, we develop the hardware-efficient BEC-SVM flame detection algorithm. Benchmarked against other prominent detection modules using the FlaDE dataset, our approach highlights the feasibility of leveraging event data for robust flame detection, achieving a detection accuracy of 96.6% (AP.50) with a processing speed of 505.7 FPS on CPU. This research contributes valuable insights for future advancements in flame detection methodologies. The implementation of the code is available at https://github.com/KugaMaxx/cocoa-flade.
超实时火焰检测:从事件摄像机和 FlaDE 数据集获得动态见解
与传统的基于帧的 RGB 摄像机相比,被称为事件摄像机的生物启发传感器具有显著优势,尤其是在克服静态背景、过度曝光和数据冗余等挑战方面。在本文中,我们探讨了事件相机在火焰检测方面的潜力。首先,我们建立了一个基于事件相机的开放式火焰检测数据集(FlaDE)。为了利用事件相机降低极端条件下的噪声,我们提出了一种去噪预处理模块,称为递归事件去噪器(RED)。通过利用信号和噪声之间不同的概率分布,RED 在 E-MLB 基准上达到了 0.974 (MESR),优于其他统计去噪方法。此外,我们还深入研究了事件率背后的物理意义,从而能够在静态背景和其他动态源中对火焰进行统计提取。在此基础上,我们开发了硬件高效的 BEC-SVM 火焰检测算法。通过使用 FlaDE 数据集与其他著名的检测模块进行基准测试,我们的方法凸显了利用事件数据进行稳健火焰检测的可行性,检测准确率达到 96.6% (AP.50),CPU 处理速度达到 505.7 FPS。这项研究为火焰检测方法的未来发展提供了宝贵的见解。代码实现可在 https://github.com/KugaMaxx/cocoa-flade 上获取。
