Abstract

Abstract This paper discusses the day and night capability of a newly developed optical sensing suite flown on manned and unmanned aircraft in Monterey Bay and Santa Barbara, CA, during 2022 to detect marine mammals. New developments of electro-optical sensors integrated on medium and long-endurance unmanned aerial vehicles (UAVs) can provide cost-effective, qualitative sensing of marine biodiversity, to include species identification. Processing of captured imagery in both day and night applications has proven effective in removing surface-level reflections and background noise, which allows sensing of subsurface marine life to several attenuation lengths. Leveraging bioluminescence as a natural image enhancement phenomenon along with advanced signal processing of imagerycaptured by this sensing suite improves the quality of nighttime detection and species identification. Concepts and applications for this sensing suite integrated on UAV platforms for ocean food-chain modeling and maritime traffic avoidance are discussed, including deployment strategies for the Channel IslandsNational Marine Sanctuary off the California coast.

利用无人飞行器改进海洋传感

摘要本文讨论了 2022 年期间在加利福尼亚州蒙特雷湾和圣巴巴拉飞行的载人和无人飞机上新开发的光学传感套件的昼夜探测海洋哺乳动物的能力。集成在中长航时无人飞行器（UAVs）上的新开发的电子光学传感器可提供具有成本效益的海洋生物多样性定性传感，包括物种识别。事实证明，在白天和夜间对捕获的图像进行处理，可以有效地去除表面反射和背景噪声，从而可以在几个衰减长度范围内感知地表下的海洋生物。将生物发光作为一种自然图像增强现象加以利用，并对该传感套件捕获的图像进行先进的信号处理，可提高夜间探测和物种识别的质量。讨论了将该传感套件集成到无人机平台上用于海洋食物链建模和海上交通避让的概念和应用，包括加利福尼亚海岸外海峡群岛国家海洋保护区的部署战略。
