Embodiment Construction
[0028] In order to make the purpose, method and advantages of the present invention clearer, the implementation method of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0029] This embodiment provides a hyperspectral imaging method based on unsupervised network solution dispersion blur, see figure 1 , including:
[0030] S1: Collect RGB data with ambiguous dispersion.
[0031] The acquisition of dispersion RGB data can be realized through a dispersion component and an image sensor. Figure 5 (a) is the simulated dispersion RGB image D. The hyperspectral data S is a three-dimensional cube data with a size of y×x×c, where x and y represent the horizontal and vertical dimensions of the image in two-dimensional space respectively, c is the number of spectral channels, and the two-dimensional Data represent spectral signals in this band. Then the dispersion RGB image D can be expressed as:
[0032] D=ΩΦS
