The present invention provides a method and device for acquiring image data. The method includes: when sending the Mth acquisition signal to the image sensor, turning on the light source; The pulse width is less than the period of the acquisition signal; the image data of the medium corresponding to the period of the Mth acquisition signal is acquired as the first medium image data; when the M+N acquisition signal is sent to the image sensor, the light source is turned on; when the light source emits light For the second duration, turn off the light source, the second duration is longer than the first duration, and less than or equal to the period of the acquisition signal; acquire the image data of the medium corresponding to the period of the M+N+1th acquisition signal as the second medium image data. The invention can solve the problem that it is difficult to simultaneously extract the ultraviolet fluorescent anti-counterfeit features and the ultraviolet fluorescent anti-counterfeit features from the bill ultraviolet light images in the related art.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to an image data acquisition method and device. Background technique [0002] Notes of value (hereinafter referred to as notes) include a variety of anti-counterfeiting features for preventing criminals from forging. Usually, various anti-counterfeiting features included in the bill are formed by printing with different anti-counterfeiting inks, and each anti-counterfeiting feature needs to be irradiated with light of a corresponding wavelength to develop a color. The prior art discloses a bill containing ultraviolet fluorescent anti-counterfeiting features and ultraviolet phosphorescent anti-counterfeiting features. The ultraviolet fluorescent anti-counterfeiting features and ultraviolet phosphorescent anti-counterfeiting features need to be irradiated with ultraviolet light to develop color. When counterfeiting, it is necessary to use an ultraviolet light source ...
