Hyperspectral image processing method for extracting information of dickite

The present invention relates to a hyperspectral image processing method for extracting the information of dickite, wherein the wave band of dickite, obvious in spectral features, is reserved. According to the method, the images of 1355 nm, 1415 nm, 1445 nm, 2135 nm, 2180 nm, 2195 nm, 2210 nm, 2240 nm, 2255 nm, 2285 nm, 2300 nm, 2330 nm, 2390 nm and 2405 nm in wave band are extracted to be subjected to a series of judgment and calculation. Therefore, the abundance valves of dickite in different areas can be calculated within the image range. Based on the above method, wave bands, which are not obvious in spectral features, are removed, so that the spectral features of dickite can be emphasized during the information extraction process. The influence of other ground features or the noise can be relieved, and the to-be-processed data volume is reduced. Moreover, the information of a final result can be extracted based on the small amount of manual operation by utilizing the IDL program. As a result, the accurac
