Embodiment

[0049] Examples of the present invention figure 1 As shown, a method for generating a quick view of a remote sensing image in a Linux environment, the remote sensing image data used in the process of generating the quick view are all image data files in BSQ format obtained after processing the original hyperspectral image (BSQ is the image data file by band Sequentially stored hyperspectral image format), the image file data format is a 32-bit single-precision floating-point type, and all that needs to be processed when generating a quick view is single-band image data information. The steps of the method are as follows:

[0050] 1) BSQ format image generates TIF format image

[0051] Because hyperspectral image data cannot be directly converted from BSQ format to JPEG format, it is necessary to convert hyperspectral image data in BSQ format into TIF format images first, and then convert from TIF format to JPEG format (both are 8-bit Figure); the steps to generate a TIF forma...

Abstract

The invention discloses a method for generating a remote sensing image quick view under Linux environment and belongs to the technical field of remote sensing image processing. The method comprises that (1) an image of a band sequence (BSQ) format is generated to an image of a tagged image file (TIF) format and (2) a quick view file of a joint photographic experts group (JPEG) format is generated, wherein the step (1) comprises of a, linear mapping, b, pretreatment of decimal part of image data, c, cutting of image data in accordance with a threshold, d, histogram equalization and e, generation of an image file of the TIF format. The method has the advantages of being simple and easy to operate. The generated quick view can describe data information of a current wave band of a hyperspectral image accurately, the method is used for processing 8-position unsigned char type data converted from 32-position single precision floating point type data, and the quantification method has low noise.

Description

technical field [0001] The invention belongs to the technical field of remote sensing image processing, in particular to a method for generating a quick view of a remote sensing image under a Linux environment. Background technique [0002] Remote sensing image quick view has broad application prospects in the following fields: [0003] (1) Hyperspectral remote sensing is the frontier field of current remote sensing technology. It uses electromagnetic waves reflected by objects of interest to obtain relevant data. It contains rich triple information of space, radiation and spectrum. The emergence of hyperspectral remote sensing is a revolution in the field of remote sensing. It enables the substances that cannot be detected in broadband remote sensing to be detected in hyperspectral remote sensing. The fast view is a necessary real-time detection method and auxiliary means in the process of hyperspectral image processing. [0004] (2) Using fast view in the field of hypers...
