Problems solved by technology

However, on this false-color image, the reproduced "object color" moves one color position toward the short-wave band direction, that is, "green" objects appear blue, "red" objects appear green, and "near-infrared strong reflection" objects appear Red, this color does not conform to the public's visual perception, which affects its application in a wider range of fields

Embodiment Construction

[0029] The present invention proposes a satellite remote sensing image generation method and system thereof, which are described in detail in conjunction with the accompanying drawings and embodiments as follows.

[0030] The color of natural objects depends on its spectral response characteristics in the visible spectrum. According to Grassmann's color mixing law, human vision can only distinguish three kinds of changes in color, namely hue, saturation and lightness. Among them, color refers to the category of color, which depends on the dominant wavelength of the object's selective reflection spectrum, and is the basic characteristic for distinguishing colors from each other. The radiation of different wavelengths in the visible spectrum is visually represented as different colors; and the color of ground objects on multi-spectral remote sensing images is not only related to the color synthesis scheme, but also depends on its spectral response characteristics in each band ....

Abstract

The invention discloses a satellite remote sensing image generating method and a satellite remote sensing image generating system. The method comprises the following steps of: S1, combining a green band image and a near infrared band image of a satellite multispectral camera to form a newly generated band image; S2, performing color synthesis by using color adding synthesis of three primary colors to generate a synthesized image, wherein the newly generated band image is adopted in a green channel; and S3, performing color and tone adjustment on the synthesized image generated in the step S2 to generate a final image. The method and the system can improve the color fidelity and definition of the satellite remote sensing image, and increase the information quantity of the satellite remote sensing image.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and system for generating satellite remote sensing images with clear and vivid colors of ground objects. Background technique [0002] Multi-spectral remote sensing (multi-band remote sensing) is a kind of continuous electromagnetic spectrum with a wide range of ground radiation, which is divided into several narrow spectral segments (bands). The technique of obtaining information in different bands of the same target is the most important and basic technical means of remote sensing at present. [0003] The color vision of the human eye is a subjective experience produced by the stimulation of visible light by three kinds of cone cells of the retina (red-sensing unit, green-sensing unit and blue-sensing unit). According to the principle of three-primary color vision, human eyes can decompose red, green, and blue colors from sunlight, and as long as there are re...
