Abstract

The present invention provides a full-spectrum hyperspectral image simulation method and device. The method generates image spectral data for data source image data, and performs spectral matching, initial endmember spectral data calculation and correction based on the full-spectrum spectral library. Considering Considering the invariance of ground object components in the image, combined with the corrected full-spectrum spectral data of ground objects, the full-spectrum hyperspectral image data of the data source image data is obtained through hybrid calculation. This realizes the simulation of remote sensing data in the full optical spectrum, which can be directly applied to each band.

Description

technical field [0001] The present invention relates to the technical field of image simulation, and more specifically, to a full-spectrum hyperspectral image simulation method and device. Background technique [0002] Hyperspectral image technology is the integration of spectral analysis technology and image processing technology at the technical level. Based on the advantages of these two technologies, hyperspectral image technology can not only detect the external characteristics of the research object such as color, shape, and texture, but also detect the external characteristics of the research object. Therefore, it has been widely used in the fields of military, geological survey and agricultural detection. [0003] With the continuous development of remote sensing science, the imaging quality of hyperspectral images has been greatly improved. However, due to the limitations of imager physical defects, atmospheric pollution, transmission loss, and calibration errors, i...
