Using the ATp9100 ground object spectral radiometer to measure typical materials , obtain theispectral rellectance images , and perform uncertainty calculations and comparative analysis,The average relativeuneertainty of various materials is caeulated to be below 6%; The phenomenon of “ homochromaticmetamerism” was verified through test data, and the results showed that objects with the same color. Theispectral rellectance may also vary.lt leads to the latest progress and development trend of hyperspectral stealthteehnology,integrating scientifie research content into teaching work.
