Oilspillnets: detecting and estimating oil spills using fusion
摘要
Oil pollution poses a significant environmental threat to oceanic and coastal ecosystems, with severe consequences for marine biodiversity, water quality, and local economies. The recent sinking of the MT Terranova tanker in Manila Bay (25 July 2024) released 1.5 million liters of industrial oil into the sea, exacerbating ongoing spill risks. Previous large-scale incidents (e.g., Deepwater Horizon, 2010; Exxon Valdez, 1989) have demonstrated catastrophic ecological and economic impacts, underscoring the need for rapid detection and monitoring. In this work, we propose an end-to-end oil spill monitoring system, "OilSpillNets". Our approach employs a late-fusion (ensemble) strategy that integrates heterogeneous satellite imagery with high-resolution drone data. By capturing large-scale spill patterns via Synthetic Aperture Radar (SAR) and finer details (including oil thickness estimation) from drone imagery, the system provides a comprehensive view of the extent and characteristics of the slick. Lightweight deep learning models are trained on this multimodal dataset and optimised for edge deployment. Evaluation on low-power platforms (Intel Movidius Myriad X and Rockchip RK3588S) demonstrates real-time performance, with the RK3588S achieving 76 FPS at a power consumption of 3.2 W. These results indicate that our framework can be deployed cost-effectively on satellites, drones, or surface vessels to provide timely early warnings and support cleanup efforts.
