| 摘 要： | 针对FY3D/MERSI和EOS/MODIS的云检测问题，提出了一种基于深度学习技术的全自动云检测算法，首次将深度学习引入到卫星影像云检测领域。本算法使用深度全卷积神经网络（Deep Convolutional Neural Networks）作为核心结构，基于EOS/MODIS基本云检测原理选择合适的通道作为特性向量参数，针对不同的场景进行分类和网络模型的训练，最终得到基于深度学习的云检测模型。经过EOS/MODIS数据和FY3D/MERSI数据的测试，云检测的精度达到98%以上，可以看出基于深度学习的云检测算法能够用于云检测，该算法具有效率高、精度高等特点，云检测效果理想。

| Abstract: | Based on deep learning technology,a fully automatic cloud detection algorithm for FY3D/MERSI and EOS/MODIS image is proposed and is firstly introduced in cloud detection study.Using Deep Convolutional Neural Networks as core structure and choosing some appropriate channels as characteristic parameters based on MODIS basic cloud detection theory,classifying and network model training are conducted according to the different scenarios.As a result,cloud detection model based on deep learning is setup and its cloud detection accuracy is over 98% by testing EOS/MODIS and FY3D/MERSI data,indicating that the algorithm can be applied in cloud detection with the characteristics of high efficiency and high accuracy as well as ideal cloud detection effect. |
