  • 结合机器学习与物理模型,实现无人参与的自动检测。
  • 日度分析可自动识别大部分大型泄漏,误报极低。
  • 发现至少25%的大泄漏曾被人工遗漏,适合遥感监测应用。

未来成像光谱仪将使数据量扩大数个数量级,亟需自动化方法来替代人工密集型的痕量气体点源检测。本文提出一种完全自动化的检测与标注方法,融合基于机器学习的形态分析与基于物理的光谱模型拟合。该方法部署于EMIT成像光谱仪数据,运行于两种模式:第一,每日自动处理所有下传数据,生成“日度摘要”,标记最大事件以供即时响应;结果表明,绝大部分大型泄漏可被准确自动识别,且误报极少,达到新的检测精度里程碑。第二,用于回溯分析,发现至少25%的大规模泄漏在现有人工审查流程中因确认偏见和视觉线索模糊而被遗漏。最后,将检测扩展至三种研究不足的痕量气体:氨气(NH3)、二氧化氮(NO2)及首次在EMIT影像中观测到的一氧化碳(CO)泄漏。

原文摘要 · Abstract (English)

Future imaging spectrometers will expand contemporary data volumes by orders of magnitude, requiring automated methods to upscale labor-intensive detection of trace gas point sources. Here we present a fully-automated approach that achieves operational performance for plume detection and labelling without human participation. Our method combines machine learning (ML)-based morphological analysis with physics-based spectroscopic model fitting. We deploy it on data from the EMIT imaging spectrometer, operating in two modes. First, we present a "daily digest" that runs automatically on all downlinked data, flagging the largest events for immediate response. The daily digest demonstrates that a significant fraction of the largest plumes can be detected automatically with negligible false positives. This represents a significant new high-water mark in plume detection accuracy. Second, we use it for retrospective analysis to find plumes that were missed by the existing human review process. We observe that at least 25% of large plumes may have been passed over in the existing workflow due to confirmation bias and ambiguity in the visual cues used by human reviewers. Finally, we extend detection to three understudied trace gases: NH3, NO2 and the first observations of carbon monoxide (CO) plume in EMIT imagery.
