Abstract
The present application relates to a detection method, belonging to the technical field of anti-fake detection. The detection method comprises steps of: acquiring reference imaging spectral data and imaging spectral data of a surface of an object to be detected; obtaining spectral reflectance of the surface of the object to be detected according to the reference imaging spectral data and the imaging spectral data of the surface of the object to be detected; matching the spectral reflectance of the object to be detected with spectral reflectance, stored in a calibration library, of an original object corresponding to the object to be detected; determining that the object to be detected is consistent with the original object if the matching of spectral reflectance is successful; and determining that the object to be detected is not consistent with the original object if the matching of spectral reflectance is failed.
