Abstract Nighttime light remote sensing images show significant application potential in marine ship monitoring, but in areas where ships are densely distributed, the detection accuracy of the current methods is still limited. This article considered the LJ1-01 data as an example, compared with the National Polar-orbiting Partnership (NPP)/Visible Infrared Imaging Radiometer Suite (VIIRS) data, and explored the application of high-resolution nighttime light images in marine ship detection. The radiation values of the aforementioned two images were corrected to achieve consistency, and the interference light sources of the ship light were filtered. Then, when the threshold segmentation and two-parameter constant false alarm rate methods are combined, the ships’ location information was with obtained, and the reliability of the results was analyzed. The results show that the LJ1-01 data can not only record more potential ship light but also distinguish the ship light and background noise in the data. The detection accuracy of the LJ1-01 data in both ship detection methods is significantly higher than that of the NPP/VIIRS data. This study analyzes the characteristics, performance, and application potential of the high-resolution nighttime light data in the detection of marine vessels. The relevant results can provide a reference for the high-precision monitoring of nighttime marine ships.

探索高分辨率夜间光遥感影像在夜间海上船舶检测中的应用——以LJ1-01数据为例

摘要 夜间光遥感图像在海洋船舶监测中具有巨大的应用潜力，但在船舶分布密集的地区，现有方法的检测精度仍然有限​​。本文以LJ1-01数据为例，与美国国家极地轨道合作伙伴（NPP）/可见红外成像辐射计套件（VIIRS）数据进行对比，探讨高分辨率夜间光图像在海洋船舶探测中的应用。对上述两幅图像的辐射值进行校正以达到一致性，并过滤掉舰船灯光的干扰光源。然后，结合阈值分割和二参数恒定误报率方法，获得船舶位置信息，并分析结果的可靠性。结果表明，LJ1-01数据不仅可以记录更多潜在的船舶灯光，而且可以区分数据中的船舶灯光和背景噪声。LJ1-01数据在两种舰船探测方法中的探测精度均明显高于NPP/VIIRS数据。本研究分析了高分辨率夜间光数据在船舶探测中的特点、性能和应用潜力。相关结果可为夜间海上船舶的高精度监测提供参考。本研究分析了高分辨率夜间光数据在船舶探测中的特点、性能和应用潜力。相关结果可为夜间海上船舶的高精度监测提供参考。本研究分析了高分辨率夜间光数据在船舶探测中的特点、性能和应用潜力。相关结果可为夜间海上船舶的高精度监测提供参考。
