Abstract
The invention discloses a kind of bottom label for false proof double-layer label, this bottom label is random grain label, it is as follows that it generates method: 1) the random shading to bottom label, use pseudorandom number generator, at any one location of pixels, randomly generate blank or grey or the color specified；2) to the shading random grain generating, use SIFT feature detection, if detecting at least 300 notable local singularity SIFT feature points, then preserve, proceed to step 3)；Otherwise abandon the shading of this generation, proceed to step 1)；3) when being printed on commodity package, the length and width size of this random grain is accurately controlled.The shading of the present invention is simply special and uncomplicated, quickly can realize the registration of lower floor's label according to this shading.
Description
Technical field
The present invention relates to anti-false trademark technology, particularly relate to a kind of bottom label for false proof double-layer label.
Background technology
At present, false proof has been the indispensable technology such as commodity circulation, sale.Current anti-counterfeiting technology method master
Quick Response Code to be had, laser holography, fluorescent material, water marked paper etc..The semantic information of Quick Response Code be easy to understand but be also easy to by
Replicate；Laser holography, fluorescent material, main attention is placed on anti-fake material and complicated texture by the method such as water marked paper
Face, production cost is high, technical sophistication and be unfavorable for large-scale promotion.
The double-layer label occurring for solving this problem, needs one design simple and special, with low cost and reliable
Property good bottom label, solve and purely rely on material with complex and complex texture to carry out false proof high cost problem.
Content of the invention
The technical problem to be solved in the present invention is for defect of the prior art, provides a kind of for false proof bilayer
The bottom label of label.
The technical solution adopted for the present invention to solve the technical problems is: a kind of bottom mark for false proof double-layer label
Signing, this bottom label is random grain label, and it is as follows that it generates method:
1) the random shading to bottom label, uses pseudorandom number generator, at any one location of pixels, randomly generates blank
Or grey or the color specified, it is not necessary to specify the pixel value of each location of pixels in advance；
2) to the shading random grain generating, SIFT feature detection is used, if detecting at least 300 notable local singularity
SIFT feature point, then preserve, proceed to step 3)；Otherwise abandon the shading of this generation, proceed to step 1)；
3) when being printed on commodity package, the length and width size of this random grain is accurately controlled, described under
The area of layer label is more than or equal to 3 times of upper label area.
The operation principle of the present invention: on lower floor's label, either manually or mechanically puts up good antifalse label, it is thus achieved that double-deck anti-
Pseudo-label.Use SIFT feature detection to this Double-layer anti-foring label, extract and preserve the SIFT feature point of proper proportion.At commodity
The inspection true and false stage, the semantic information of checking antifalsification label of directly being taken pictures by mobile phone A pp, it is thus achieved that the information of commodity, it is possible to obtain
The information such as the place of production of commodity, manufacturer.By carrying out to the label of real goods and commodity to be tested shooting imaging, count respectively
Calculate in two width pictures antifalsification label relative to the relative displacement of lower floor's shading.Owing to lower floor's label has abundant SIFT feature,
Can be used to carry out the accuracy registration of shading, the upper label calculating on the basis of this registration is relative to the displacement information of lower floor's label
Can be as accurate as 0.05mm magnitude.
Even if lower floor's texture label and upper label are not all forged person and accurately replicate, at mechanically actuated or manual bar
Under part, it is extremely difficult to replicate the displacement information relative to lower floor's label for the real goods antifalsification label.
The beneficial effect comprise that: shading is simply special and uncomplicated, under can quickly realizing according to this shading
The registration of layer label.
Brief description
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing:
Fig. 1 is the false proof lower floor grey random tags figure of the embodiment of the present invention；
Fig. 2 is the effect schematic diagram putting up upper strata anti-false sign label on the random shading of grey.
Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with embodiment, to the present invention
It is further elaborated.It should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not used to limit
Determine the present invention.
A kind of bottom label for false proof double-layer label, this bottom label is random grain label, and it generates method
As follows:
1) the random shading to bottom label, uses pseudorandom number generator, at any one location of pixels, randomly generates blank
Or grey or the color specified；
2) to the shading random grain generating, SIFT feature detection is used, if detecting the notable local singularity of at least 300
SIFT feature point, then preserve, proceed to step 3)；Otherwise abandon the shading of this generation, proceed to step 1)；
3) when being printed on commodity package, the length and width size of this random grain is accurately controlled.
Fig. 1 is bottom label provided by the present invention；And Fig. 2 be cover on lower floor's random grain label specific false proof
The effect schematic diagram of label.
Double-layer label involved in the present invention is as follows, comprising:
Upper label and lower floor's label；
The overall boundary of described upper label is in the bounds of lower floor's label；
The texture information of described lower floor label is the texture information extracting for SIFT feature.
Wherein, the texture information of described upper label is the texture information including merchandise news.
Commonly using, described upper label is two-dimension code label, the merchandise news that upper label includes include trade name,
The commodity place of production and manufacturer.
The texture information of upper label includes the shade of gray characteristic information enriching.The area of lower floor's label is more than or equal to upper
3 times of layer label area.
It should be appreciated that for those of ordinary skills, can be improved according to the above description or be converted,
And all these modifications and variations all should belong to the protection domain of claims of the present invention.
