Abstract

Forest wildfire has great impacts on both nature and human society. While disrupts the ecosystems, wildfire leads to significant economic loss and poses a threat to local communities. To detect forest wildfire, remote sensing technology has become an essential and powerful tool. Compared with polar-orbiting satellite, the new generation of geostationary satellite provides higher temporal resolution and faster response capability. In this study, we utilize the near real-time data of Himawari-8/9 satellite, to achieve 10-min forest early wildfire detection. A recursive transformer model is proposed in this work. It fuses multi-type and multi-source information for Himawari-8/9 satellite. By leveraging the spectral, temporal and spatial features of fire pixels and considering land cover information, the proposed method reduces interference factors like cloud and terrain, resulting in minute-level and near real-time detection of forest wildfire. In 21 ground truth forest wildfire scenarios and MODIS-based cross-validation dataset, the proposed method achieves better results compared to the JAXA wildfire product, in terms of overall fire detection accuracy, early fire detection rate, omission rate, and real-time performance. Furthermore, the proposed framework effectively lowers the emergency response time for early forest wildfire detection, thereby reducing the loss caused by forest wildfire.
10分钟森林野火早期探测:通过递归变压器融合多类型多源信息
森林野火对自然和人类社会都有很大的影响。野火在破坏生态系统的同时,还会造成重大的经济损失,并对当地社区构成威胁。对于森林野火的探测,遥感技术已经成为必不可少的有力工具。与极轨卫星相比,新一代地球静止卫星具有更高的时间分辨率和更快的响应能力。在本研究中,我们利用Himawari-8/9卫星的近实时数据,实现了10分钟森林野火早期检测。本文提出了一种递归变压器模型。它融合了hima -8/9卫星的多类型、多源信息。该方法利用火灾像元的光谱、时空特征,结合土地覆盖信息,降低了云和地形等干扰因素,实现了分分钟级、近实时的森林野火检测。在21个地真森林野火场景和基于modis的交叉验证数据集中,本文方法在整体火灾探测精度、早期火灾探测率、漏报率和实时性等方面均优于JAXA野火产品。此外,该框架有效缩短了森林野火早期检测的应急响应时间,从而减少了森林野火造成的损失。
