基于光谱阈值法和分裂合并聚类算法的“HY-1A”CCD云检测算法和应用
The application analysis of spectrum threshold and MSC cloud detection algorithms based on “HY-1A” CCD data

摘要: “海洋1号A”卫星(简称“HY-1A”)是我国第一颗海洋卫星,它搭载了水色扫描仪和CCD成像仪,其中CCD成像仪主要应用于海岸带地区.为了对海岸带地区进行准确的信息提取和分析,必须去除云的影响和干扰,因此本文针对“HY-1A”CCD数据的特点,对云检测算法进行了评估、遴选和改造,实现了业务化应用,这也是“HY-1A”卫星CCD成像仪海岸带应用示范系统的重要工作之一.云检测的方法众多,主要可以分为可见光/红外阈值法和聚类法两种,每种方法还可以辅以空间均匀性判识.
