Python | OmniCloudMask 卫星影像云掩膜

Python | OmniCloudMask 卫星影像云掩膜

云与云影掩膜（Cloud & Cloud Shadow Mask）是光学遥感影像预处理中的关键步骤，直接影响地表反射率合成、植被指数计算、土地覆盖分类、变化检测和时间序列建模的可靠性。传统云检测方法通常依赖固定阈值、传感器专用质量波段或经验规则，在跨传感器、跨处理级别和复杂地表背景下容易出现云边界漏检、薄云误判和云影混淆等问题。OmniCloudMask 是 DPIRD-DMA 开源的 Python 库，面向高至中等空间分辨率卫星影像实现快速云与云影语义分割，可用于 Sentinel-2、Landsat 8、PlanetScope、Maxar 以及其他包含红光、绿光和近红外波段的影像数据。
