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型的多摄像头系统，以永久观察活火山。与当前能力相比，该创新系统将节省专家的成本，功耗，数据量和图像分析时间。该系统将在可见的，红外和紫外线范围内连续监视火山，并自主确定何时使用自动图像分析在每个波长中捕获视频。随后，该系统将分析这些视频以提取重要的监测参数，包括火山发射的气体和灰烬的数量以及爆炸性事件的频率和强度。这些信息不仅将推进火山预测的努力，而且还有助于更好地理解导致火山喷发的机制。大多数火山在重大喷发前表现出早期的动荡迹象，其中可能包括增加脱气，隐蔽性，隐蔽性，隐蔽性，或爆炸的频率更高。但是，在许多情况下，这些关键指标未记录。提出了用于视觉，热和气体监测的集成多摄像机系统的开发。即使在电力和数据传输功能受到严重限制的偏远地区，也可以部署该系统以连续和实时监视活动火山。除了在三个光谱范围内的结合观察和提议系统的低成本外，其新颖性还存在于其边缘计算方法中，图像处理是由系统和诸如事件检测，羽状高度，体积，音量，上升速度和SO2通量等参数进行的，自动计算的，这些奖项是自动计算的。这些奖项反映了NSF的构建范围和良好的依据，其智力和构建均具有良好的影响。 标准。
