Technical field

The present invention relates to field of anti-counterfeit technology more particularly to a kind of identification of ink label test fake method, device, equipment and Medium.

Background technique

The packages printing industry in China is grown rapidly, antifalsification label using more more and more universal, especially in drug, cigarette It is commonly used in the packaging of equal high-end products, to reach antifalse effect.

But with antifalsification label it is universal after, fake producer in the market carries out antifalsification label with high simulation means pseudo- It makes, to realize the fraud to high-end product；What is more, and the outer packing for directly recycling high-end commodity goes to re-work, and is made with this Vacation deception consumer, disrupts the market.But ordinary consumer lacks the recognition capability of profession to these antifalsification labels, and The phenomenon that being applied to commodity counterfeit prevention to antifalsification label has also been accustomed to, and general no one goes carefully to distinguish in daily life Whether these commodity for being printed on antifalsification label are certified products.

Commonly used antifalsification label in the market, including laser label and ink label, existing radium-shine figure line are usual Laser label is formed using will be printed on the laser film of figure line and be transferred on wrapping paper by being bonded the processes such as compound, but due to radium-shine The extensive utilization of transfer membrane, existing radium-shine figure line are very easy to copy, and greatly reduce its anti-fake effect.

Therefore, it goes to realize commodity counterfeit prevention using ink label, has better effect, the printing of ink label general random Ink layer is formed, and the depth, the shape of the ink logo formed are uncertain, has randomness and uniqueness, therefore to such The identification of ink label and verification process are relatively complicated, if the ink layer of ink label is superimposed radium-shine figure layer, will form Static and dynamic security pattern has stronger antifalse effect.So needing to propose a kind of needle after ink label puts goods on the market To the identification verification method of ink label, completes the identification to security pattern in ink label and verify.

Summary of the invention

For overcome the deficiencies in the prior art, one of the objects of the present invention is to provide a kind of identifications of ink label to test puppet Method obtains the ink feature information of ink label, utilizes what is extracted by carrying out feature extraction to ink label image Ink feature information carries out testing puppet, to complete the puppet of testing to product, and then can preferably safeguard consumer's interests.

An object of the present invention is implemented with the following technical solutions:

Fake method is tested in a kind of identification of ink label, comprising the following steps:

Ink label image is obtained, the ink label image is identified to extract ink characteristic information；

Validation template is obtained, the ink feature information and validation template are subjected to aspect ratio pair, obtain aspect ratio to knot Fruit；

Pseudo- result is tested as a result, returning according to the aspect ratio pair.

Further, validation template, the unique identification of the ink label are obtained by the unique identification of ink label are as follows: The tag number of the bar code information or ink label bound with the validation template of ink label.

Further, the ink label image is identified to extract ink characteristic information, it is specific to extract step Suddenly include:

The ink label image is pre-processed, according to figure location feature, from the pretreated ink mark The position that positioning pattern is determined in image is signed,

According to the position of target signature and the positioning pattern, anti-fake region is determined；

The anti-fake region is corrected by affine transformation；

Anti-fake region after correction is subjected to binary conversion treatment, obtains binary map；

The binary map is drawn and is divided into several piecemeals, the accounting of ink in each piecemeal is calculated, if the accounting is greater than Or be equal to threshold value, then the value of piecemeal is set to 0, otherwise is set to 1；The value of several piecemeals is combined into binary system in order Number, the binary number are ink feature information.

Further, when ink label includes radium-shine figure layer, the color change of the ink label image is also analyzed, with Judge whether the color change rule for meeting the ink label comprising following steps:

Ink label image described in multiframe is obtained, the ink label image is converted into HSV color space；

The HSV color space of ink label image described in multiframe is recorded, is analyzed each in ink label image described in multiframe The color change of pixel then meets the ink when the pixel quantity of the color change and the condition of distribution satisfaction setting The color change rule of label, conversely, not meeting then；

Wherein, pass through color change described in VIBE algorithm, mixed Gauss model or deep learning model analysis.

Further, candidate anti-fake region is formed by the position of positioning pattern described in permutation and combination, further according to target spy Sign determines the anti-fake region from the candidate region.

Further, it carries out testing pseudo- comparison using the ink feature information extracted, testing pseudo- comparison process includes: by institute It states ink feature information validation template corresponding with the pre-stored ink label to be compared, when comparing successfully, then Puppet is tested to pass through；Do not pass through conversely, testing puppet.

Further, it carries out testing pseudo- comparison using the ink feature information extracted, testing pseudo- comparison process includes: by institute It states ink feature information validation template corresponding with the pre-stored ink label to be compared, when comparing successfully and meet When the color change rule, then tests puppet and pass through；Do not pass through conversely, testing puppet.

The second object of the present invention is that pseudo-device is tested in the identification for providing a kind of ink label, passes through the oil of ink label Black pattern and laser pattern carry out identifying processing and verifying respectively, to carry out testing puppet to commodity.

The second object of the present invention is implemented with the following technical solutions:

Pseudo-device is tested in a kind of identification of ink label comprising:

Image collection module identifies with extract oil the ink label image for obtaining ink label image Black characteristic information；

Pseudo- module is tested, for obtaining validation template, the ink feature information and validation template is subjected to aspect ratio pair, obtained To feature comparison result；

As a result output module, for testing pseudo- result as a result, returning according to the aspect ratio pair.

The third object of the present invention is to provide the electronic equipment for executing one of goal of the invention comprising processor, storage Medium and computer program, the computer program are stored in storage medium, and the computer program is executed by processor Fake method is tested in the identification of Shi Shixian above-mentioned ink label.

The fourth object of the present invention is to provide the computer readable storage medium of one of storage goal of the invention, store thereon There is computer program, the computer program realizes that fake method is tested in the identification of above-mentioned ink label when being executed by processor.

Compared with prior art, the beneficial effects of the present invention are:

The present invention is by identifying the ink feature in ink label and feature extraction, the ink that will finally extract Characteristic information is compared with validation template predetermined, so as to complete the verifying to ink label, to realize that product is tested Puppet, and then achieve the purpose that safeguard consumer's interests, when the ink label to the radium-shine figure layer of superposition carries out identification and feature extraction When, it will also extract radium-shine characteristic information and be compared with validation template, be able to achieve and different types of ink label is identified Test puppet.
