Hyperspectral data acquisition, correction, and machine vision application flow chart. (a–d) Outdoor acquisition system; (a) Hyperspectral camera; (b) Fixator knob; regulate loose and tight; (c) Fixer handle, adjust the camera angle; (d) Tripod. (a–g) Indoor acquisition system; (e) Indoor system console - simulating light sources; (f) Camera telescopic frame; (g) Console base, control camera moving up and down and light switch. An) Information to be tested after correction; Bn) identification result; n = 1, 2, 3, 4. DET: Detachment; FIML: Features Induced by Material Loss; DD: Discoloration & Deposit; BC: Biological Colonization. Where Ι is the corrected reflectance, R0 is the original reflectance, RD is the dark reference spectrum, and Rw is the white reference spectrum.
