    摘要:

    裁剪20090716和20090730兩景HJ-1 CCD多光譜影像的部分作為試驗(yàn)區(qū)，基于面向?qū)ο蠓▽?shí)現(xiàn)了厚云、薄云及云影的檢測(cè)，進(jìn)而利用替換法去除云和云影。對(duì)原影像、去云后影像的像元灰度均值、最大值、標(biāo)準(zhǔn)差、熵等指標(biāo)進(jìn)行了比較，結(jié)果表明，還原后的影像符合地面實(shí)際，面向?qū)ο笈c替換法可作為HJ-1 CCD多光譜數(shù)據(jù)的云檢測(cè)與去除的重要方法。

    Abstract:

    Parts of 20090716 and 20090730 HJ-1 CCD multi-spectral images were cut as the experimental areas. The thick cloud, thin cloud and cloud shadow were detected based on object-oriented method. And then, the substitution method was used to remove the cloud and cloud shadow. The comparison of pixel gray mean, maximum, standard deviation and entropy of original image and restored image indicated that the restored image accorded with the ground truth. The object-oriented and substitution could be an important method in the cloud detection and removal of HJ-1 CCD multi-spectral image.
