Remote sensing image color correction method and system based on cloud mask and MSR

Abstract

The invention relates to a remote sensing image color correction method and system based on a cloud mask and an MSR, and the method comprises the steps: 1, reconstructing a remote sensing image through the cloud mask; 2, processing the remote sensing image by using an MSR method; 3, calculating a Dynamic value; and 4, performing maximum value and minimum value stretching to generate a color correction result. The defects in the prior art are overcome; the problems of color cast, insufficient color contrast, overexposure caused by common correction and the like of the remote sensing image are well solved; the method is high in automation degree, method universality degree and color rendition degree, the artificial color correction processing cost can be greatly reduced, and the method can be applied to color correction of a large number of remote sensing images and has wide application prospects and value.

Description

technical field [0001] The invention belongs to the technical field of intersecting remote sensing and computer processing, and relates to a remote sensing image color correction method and system based on cloud pickling film and MSR. Background technique [0002] Remote sensing technology emerged in the 1960s. At present, remote sensing technology has been widely used in meteorology, ocean, agriculture, land, water conservancy, surveying and mapping, environmental protection and other industries. Compared with traditional monitoring methods, remote sensing technology has many unique advantages such as timeliness, extensiveness, objectivity, and economy. [0003] my country's remote sensing satellite technology started relatively late. The first remote sensing satellite launched in 1975 preliminarily solved the problem of the urgent need for satellite remote sensing sources for national surveys; however, my country's remote sensing satellite technology has developed rapidly....
