Embodiment Construction
[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.
[0042] Hyperspectral image information has a very broad spectrum coverage, including visible light, near-infrared, mid-infrared and thermal infrared bands. In these spectral ranges, it accurately records the spectral reflectance of the target. Due to the continuity of the spectrum, it can Provide a continuous spectrum curve to realize the simultaneous recording of target spectral information and spatial information. Hyperspectral imaging technology has high spectral resolution and small spectral intervals, so adjacent spectra contain a large amount of overlapping information, which provides the possibility for continuous imaging of images. Due to the differences in the material composition of different ground objects, they have different spectral reflectance characteristic cu...
