Cloud determination method and system for remote sensing satellite images

Abstract

The invention discloses a cloud determination method and a system for remote sensing satellite images. The method includes: receiving remote sensing satellite image data; performing format-removing processing of the remote sensing satellite image data; according to a preset data sharding rule, partitioning the remote sensing satellite image data after format-removing processing, and obtaining a plurality of sub-image data; and with the combination of texture features of visible light images, conducting cloud detection of each sub-image data by employing a classifier of a support vector machine in order to recognize a cloud mask in the remote sensing satellite image data. According to the method and the system, compared with cloud mask recognition of multi-spectrum images in the remote sensing satellite images in the prior art, cloud mask recognition is realized by employing the classifier of the support vector machine with the combination of the remote sensing satellite images and the texture features of the visible light images, the accuracy of the scheme can be effectively guaranteed via a general and engineering design, the cloud mask and other target substances such as snow and sand are effectively distinguished and classified, and the recognition rate can be high.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a cloud judgment method and system for remote sensing satellite images. Background technique [0002] In remote sensing satellite image data, due to the limitation of climate and other conditions, there is a large amount of data covered by clouds. These data themselves have no intelligence value, but they occupy the storage resources of the ground data processing system, which is difficult for later interpretation work, Information production, etc. bring interference. [0003] Therefore, in order to solve this interference, it is necessary to identify the cloud masks in the received remote sensing satellite image data, and then remove the invalid data covered by clouds corresponding to these cloud masks in subsequent operations. Contents of the invention [0004] In view of this, the present invention provides a method and system for cloud judgment of remote sensing s...
