This project aims at developing a novel Multi-Camera system for the permanent observation of active volcanoes. This innovative system will save on cost, power consumption, data volume and image analysis time by experts, compared to current capacities. The system will continuously monitor the volcano in the visible, infrared, and ultraviolet ranges and autonomously determine when to capture videos in each wavelength using automated image analysis. Subsequently, the system will analyze these videos to extract vital monitoring parameters, including the quantity of gas and ash emitted by the volcano, as well as the frequency and intensity of explosive events. This information will not only advance volcano forecasting efforts but also contribute to a better understanding of the mechanisms leading to volcanic eruptions.The majority of volcanoes exhibit early signs of unrest before a major eruption, which may include increased degassing, incandescence, or a higher frequency of explosions. However, in many instances, these critical indicators go unrecorded. The development of an integrated Multi-Camera system designed for visual, thermal, and gas monitoring is proposed. This system can be deployed for continuous and real-time monitoring of active volcanoes, even in remote areas where power and data transfer capabilities are severely limited. Besides the combined observation in three spectral ranges and the low cost of the proposed system, its novelty resides in its edge-computing approach whereby image processing is done by the system and parameters such as event detection, plume height, volume, ascent rate and SO2 flux are calculated automatically.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目旨在开发一种新的多相机系统，用于对活火山的永久观测。与目前的能力相比，这一创新系统将节省成本、功耗、数据量和专家进行图像分析的时间。该系统将在可见光、红外和紫外线范围内持续监测火山，并使用自动图像分析自主确定何时拍摄每个波长的视频。随后，该系统将分析这些视频，以提取重要的监测参数，包括火山排放的气体和火山灰的数量，以及爆炸事件的频率和强度。这些信息不仅将推动火山预报工作，还有助于更好地了解导致火山喷发的机制。大多数火山在大喷发前表现出早期的动荡迹象，可能包括脱气增加、白炽度或更高的爆炸频率。然而，在许多情况下，这些关键指标没有记录。提出了一种用于视觉、热和气体监测的集成多摄像机系统的开发。该系统可用于持续和实时监测活火山，即使在电力和数据传输能力严重有限的偏远地区也是如此。除了在三个光谱范围内的综合观测和拟议系统的低成本外，其新奇之处在于其边缘计算方法，即图像处理由系统完成，并自动计算事件检测、烟羽高度、体积、上升速率和二氧化硫通量等参数。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
