[0032] According to the material of the target corresponding to the target space information described in step 1, the corresponding normalized reflectance spectrum is selected from the spectral library to generate target spectral information.

[0033] In this embodiment, on the basis of determining the target template and grayscale information, the spectral features corresponding to the target area are generated.

[0034] Firstly, it is necessary to establish the spectral library of the target. The establishment of the spectral library can be realized by measuring the spectra of various targets, or by obtaining a mature spectral library that has been widely used. The generation of spectral information needs to select the corresponding spectrum in the spectral library according to the actual material of ...
