AI模型利用卫星图像联合检索小麦作物数据

作者 PulseAugur 编辑部 · [1 个来源] ·

研究人员开发了一种迭代能量模型Transformer (iEBT) 模型，利用卫星数据联合检索小麦作物的土壤湿度、叶面积指数和株高。该多模态Transformer处理来自Sentinel-1雷达和Sentinel-2光学图像的时间序列，通过最小化学习到的能量函数来迭代优化估计。该模型在印度田间测量数据上取得了0.854的R^2的强劲表现，表明Sentinel-1数据对于土壤湿度检索至关重要，Sentinel-2数据对于叶面积指数至关重要，而两者的结合则对株高至关重要。该模型的终端能量函数还可以作为质量诊断，通过排除高能量样本来提高准确性。 AI

影响 该模型可以通过利用易于获取的卫星数据提供更准确和集成的作物状态监测，从而增强精准农业。
