Abstract
The utility model relates to a printed matter authenticity identification device based on a multispectral imaging technology. The printed matter authenticity identification device comprises a multispectral imager for carrying out multispectral scanning on a test sample, a spectral data processor used for comparing spectral data obtained from scanning with spectral data of a standard sample, and a data server used for storing the spectral data of the standard sample, wherein the multispectral image is connected with the spectral data processor which is connected with the sample data server. Compared with the prior art, the printed matter authenticity identification device has a high-resolution characteristic of image analysis, also has a spectral analysis function, and has the characteristics of larger information quantity, stronger function and more flexible analysis method compared with the pure image analysis or spectral analysis.
Description
Technical field
The utility model relates to a kind of printed matter real and fake discrimination device, especially relates to a kind of printed matter real and fake discrimination device based on multi-optical spectrum imaging technology.
Background technology
The development that science and technology is maked rapid progress makes the offender can carry out all kinds of printing fraud activities, has brought massive losses to the country and people, and modal is exactly books and periodicals piracy, certificate fraud etc.But false proof for printed matter still mainly rests on " preventing " at present, promptly in the printing process of printed matter, adopts some special anti-counterfeit printing equipment, anti-fake material, false proof sign, antiforging printing method etc., differentiates and then carries out on this basis.But the false proof means of this type often need higher cost and technical support, false proof then inapplicable for general printed matter, particularly common publication.
Print reproduction is based on the metamerism stoichiometric operation to a certain extent, and metamerism equally also provides opportunity to lawless person's fraud, on the duplicate color, has reached the degree of looking genuine, lacks the effective identification method to the false printed matter of this kind at present.
The utility model content
The purpose of the utility model is exactly for the defective that overcomes above-mentioned prior art existence a kind of printed matter real and fake discrimination device based on multi-optical spectrum imaging technology to be provided.
The purpose of the utility model can realize through following technical scheme:
A kind of printed matter real and fake discrimination device based on multi-optical spectrum imaging technology; Comprise multi-spectral imager, spectroscopic data processor and data server; Described multi-spectral imager connects the spectroscopic data processor, and described spectroscopic data processor connects the sample data server.
Described multi-spectral imager is the multi-spectral imager that is used for specimen is carried out multispectral scanner; The spectroscopic data processor that described spectroscopic data processor compares for the spectroscopic data of spectroscopic data that scanning is obtained and standard model, described data server is the data server that is used to preserve the standard model spectroscopic data.
Described multi-spectral imager comprises light source, grating, imaging mirror and detector; Described light source, grating and imaging mirror are successively along the optical axis direction setting; Described detector connects into the picture mirror; Specimen is after imaging on the imaging mirror, and its spectroscopic data is gathered by detector, and the spectroscopic data that is sent to spectroscopic data processor and standard model compares.
Compared with prior art; The utility model had both had the high resolving power characteristic of graphical analysis; Have the spectral analysis function again, compare, have that quantity of information is bigger, function is more powerful, an analytical approach flexible characteristic more with simple graphical analysis or spectral analysis.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of printed matter real and fake discrimination device based on multi-optical spectrum imaging technology comprises the multi-spectral imager 1, spectroscopic data processor 2 and the data server 3 that connect successively; Wherein multi-spectral imager 1 is made up of light source, grating, imaging mirror and detector, and light source, grating and imaging mirror are provided with along optical axis direction successively specimen is carried out to picture, and detector connects into the picture mirror; Gather spectroscopic data; Be sent to spectroscopic data processor 2 then and handle, spectroscopic data processor 2 is transferred corresponding standard model spectroscopic data in the data server 3, compares with the spectroscopic data of specimen; If difference between the two surpasses preset threshold; Then be judged to be fakement,, then be judged to be genuine piece if do not surpass preset threshold.
Both had the high resolving power characteristic of graphical analysis, had the spectral analysis function again, compared, had that quantity of information is bigger, function is more powerful, an analytical approach flexible characteristic more with simple graphical analysis or spectral analysis.
