The coordinate system ruler, the coordinates of the electronic tag, the information code card and the auxiliary recognition image on the coordinate system scale are different, and the combination of the electronic tag, the information code card and the auxiliary recognition image can form a feature of the package, the feature involves a plurality of different With unique feature elements, the characteristics of different individual bags in the same batch are different, greatly reducing the possibility of the bag being counterfeited.

Specifically, as shown in FIG. 6, the composite packaging bag may include a packaging bag made of a double-layer material, and an RFID chip is sealed between the two-layer materials, and the RFID chip can be written into the relevant packaging bag during production or delivery. The information of the item in the package is used as the identity of the packaged delivery unit. Attempting to remove the RFID chip will inevitably result in physical damage to the package. The RFID chip is sealed between the two layers of materials by a rubber pressing process. The surface of the RFID chip is provided with a thin coil. After being sealed by the rubber pressing process, the coil is closely adhered to the two-layer material, in the process of trying to take out the RFID chip. The probability of damage to the coil is high, so that the counterfeiter not only has to imitate the plastic bag, but also needs to repair the RFID chip, which greatly increases the imitation cost.

An RFID chip and an information code card may be disposed at the same time between the two layers of materials, and the surface of the package is provided with a coordinate system and an auxiliary identification image; the RFID chip, the information code card and the auxiliary recognition image form an image fingerprint for each package. The RFID chip and the information code card are sealed by the process, and the random component positioning tolerances produced by the process are intentionally expanded, and the positions of the RFID chip and the information code card have random positioning tolerances within a controllable range, thereby causing image fingerprints of different packaging bags. The dissimilarity enables the package to be verified by image fingerprinting, thereby eliminating the possibility of the package being counterfeited. The verification of the image fingerprint is performed by an algorithm such as image recognition and comparison.

An example of an information code card is a two-dimensional code, which is a unique number of the package, which is generated by sequential numbering or non-repeating random numbers. The generation mechanism of the QR code can be adjusted every time, but the number of all the bags is unique in history. The auxiliary recognition image can be a logo or other mark pattern. The figure is a logo composed of three three squares. The information code card can be a random image code, a two-dimensional code, a random gray matrix code, and a mathematical algorithm. Image coding.

The coordinate system scale can be a cross coordinate system scale, which functions to more accurately read the position of the image fingerprint, and on the other hand, corrects the image of the wrinkled packaging bag before image recognition, and secondly, the cross coordinate system ruler can To prevent the bag from being physically stretched, the scale of the coordinate system ruler and the standard measuring instrument are mutually verified, so that the consignee can verify whether the bag is physically stretched by the coordinate system scale and the standard scale to prevent the head from being passed through the head. Cut--Stretch - Re-heat seal the bag to open the bag illegally.

In the embodiment of the present invention, an RFID chip, a two-dimensional code number, and an image fingerprint are disposed between the two-layer materials of the packaging bag to identify the packaging bag. In addition, the RFID chip is encapsulated into the packaging bag by a rubber pressing process, and the coil of the surface of the RFID chip is The two-layer material is closely attached to form a paper effect. When the counterfeiter takes it out, the package is inevitably physically damaged, and the RFID chip has a higher probability of being damaged, so that the counterfeiter not only has to imitate the plastic bag, but also needs to Repairing the RFID chip greatly increases the imitation cost; on the basis of this, the embodiment of the present invention also obtains the randomness of the position of the RFID chip and the two-dimensional code by the glue pressing process, and obtains the RFID chip, the two-dimensional code and the auxiliary identification. The image fingerprint fingerprint formed by the image further enhances the difficulty of counterfeiting and ensures the authenticity of the items in the package.

Conventionally, when using the original RFID chip of the factory, it is generally protected by brushing resin hardening, plastic sealing, injection molding, etc., and then four-side heating and ironing, fabric sewing, etc., the hardened chip is encapsulated in the hollow cavity, or glue is used. It is attached to the surface of a flat object, and the upper layer is protected by a patch. This has led to the easier removal of RFID chips in traceable packaging applications and their physical replication, resulting in advanced protection technologies such as AES. The traditional hot glue technology, in the process of higher temperature, will change the ambient Curie temperature of the RFID chip, and the set frequency of the RFID chip will be shifted due to the change of the ambient Curie temperature, which is the traditional temperature frequency deviation. The problem of shifting, which leads to the infeasibility of the hot glue pressing process, results in a light weight and low cost strict physical packaging solution that is difficult to put into practical use.

In the rubber pressure processing of the embodiment of the invention, the key link adopts the medium-low temperature glue-spraying and cold-pressing technology, and the temperature control during production is maintained during the whole process, which does not cause the frequency offset of the RFID chip, thereby Industrial production is possible.

The specially formulated glue and the bag made of special composite material make it rigid and flexible enough to be able to hang in the normal cargo range and the cold environment is basically not deformed, and it is difficult It is scratched and worn by non-sharp objects and does not damage the chip during pressing. In addition, the structure of the chip and the custom coil makes the total thickness of the chip extremely thin, so that the pressing process can form a paper surface effect without bursting out of the bubble, and the above details enable the industrial production of the technology to be implemented.

According to the above composite packaging bag, the embodiment of the present invention further provides a verification method based on the composite packaging bag, and the following is a detailed description based on an embodiment of the verification method of the composite packaging bag.

Referring to FIG. 7, a flow chart of a verification method based on a composite packaging bag of one embodiment is shown. The verification method based on the composite packaging bag in this embodiment includes the following steps:

Step S710: After the composite packaging bag is prepared, obtain a first panoramic image including an electronic label, an information code card, and an auxiliary recognition image on the composite packaging bag; and acquire a surface image fingerprint according to the first panoramic image, wherein the surface image fingerprint characterizes the electronic Label, information code card and auxiliary identification image, the relationship of goods;

In this step, the first panoramic image can be obtained by a special imaging device used in the production of the packaging bag. Since the positions of the electronic tag, the information code card and the auxiliary identification image on the composite packaging bag are different, the mutual relationship between the three can be utilized. Generating surface image fingerprints as a basis for distinguishing composite packaging bags;

Step S720: In the delivery phase, acquiring a second panoramic image of the composite package of the packaged goods, and acquiring an inner layer image fingerprint according to the second panoramic image and the surface layer fingerprint, wherein the inner layer image fingerprint represents the electronic label and the information Code cards and auxiliary recognition of the relationship between images and goods;

Step S730: Acquire an original image fingerprint according to the quantization matrix of the inner layer image fingerprint and the two-dimensional coordinate system and the relative positional relationship thereof;

In steps S720 and S730, the second panoramic image is acquired by a dedicated photographing device during the delivery process, and the surface image fingerprint and the relative spatial position of the cargo are different in plane and space, and the inner layer image fingerprint can be used for characterizing, and This obtains the quantization matrix in the three-dimensional coordinate system and the two-dimensional coordinate system and their relative positional relationship, and forms the original image fingerprint as the basis for distinguishing the cargo unit;

Step S740: Obtain a captured image of the composite packaging bag in the receiving phase, and obtain a fingerprint of the image to be tested according to the captured image;

In this step, the image fingerprint to be tested corresponds to a composite package obtained at the time of receipt;

Step S750: fitting the original image fingerprint and the fingerprint of the image to be tested to obtain a fitting degree, and if the fitting degree is greater than or equal to the preset value, determining that the composite packaging bag passes the verification.

In this step, due to the deviation of the viewing angle when the image is acquired and the wrinkles of the composite bag body, even if the same composite bag has a slight deviation between the original image fingerprint and the image fingerprint to be tested, a preset value of the fit is set. When the fitting degree is greater than or equal to the preset value, it can be determined that the composite packaging bag passes the verification, that is, the composite packaging bag is not illegally unsealed.

In this embodiment, after the composite packaging bag is manufactured and shipped, the panoramic image of the composite packaging bag is obtained, and the original image fingerprint is obtained according to the panoramic image; in the receiving phase, the captured image of the composite packaging bag is obtained, according to the shooting. The image acquires the fingerprint of the image to be tested; fits the original image fingerprint and the fingerprint of the image to be tested, and determines whether the composite packaging bag passes the verification according to the obtained fitting degree. Since the coordinates of the electronic tag, the information code card, and the auxiliary recognition image on the coordinate system scale are different, the combination of the electronic tag, the information code card, and the auxiliary recognition image may form a feature of the package, and the feature involves a plurality of different unique features. The characteristic elements and the corresponding characteristics of different packaging bags are different, and the authenticity of the packaging bag can be verified according to the characteristics of the packaging bag.

Further, it is confirmed whether the composite packaging bag is illegally unsealed during transportation; the sealing image may include a head-up image and a side image of the sealing. In the delivery phase, the original sealing image of the composite packaging bag can also be obtained, and in the receiving phase, the image of the sealed sealing bag of the composite packaging bag can be obtained, and the original side sealing image and the side sealing image to be tested can be compared.

Further, in the delivery phase, a video can be taken on the packaged bag of the packaged goods, and the second panoramic image and the original sealed image are extracted from the obtained captured video; likewise, in the receiving phase, the received composite package can be received. The bag captures a video, and the captured image and the image to be tested are extracted from the obtained captured video.

In one embodiment, the verification method of the composite package further includes the following steps:

In this embodiment, in the delivery phase, the encrypted information is obtained, and the shipping information is encrypted, and the encrypted shipping information is written into the electronic label. The shipping information is encrypted, which is equivalent to setting. Read and write permissions, the shipping information in the electronic tag is generally difficult to forge, to ensure the accuracy of the shipping information, and secondly the information stored in the electronic tag can not be changed offline, which ensures that the consignor's commitment to the content is serious and unchangeable In the receiving phase, the decryption key generated during the encryption of the delivery phase is obtained, and the information in the electronic tag is read and verified with the original recorded shipping information. If consistent, it is established according to the delivery phase. The first association relationship between the shipping information and the original image fingerprint is obtained, the reading permission of the original image fingerprint is obtained, and the original image fingerprint database is obtained, which is used for fitting and matching with the image fingerprint to be tested. In the process, using the encryption security of the shipping information and the first association relationship between the shipping information and the original image fingerprint, the shipping information and the original image finger can be avoided. Forgery, ensure the accuracy of the verification process.

Further, different original image fingerprints may constitute an original image fingerprint database, and the original image fingerprint database and the decryption key may be stored in an independently encrypted information database, and the encrypted information is acquired by using a random encryption mechanism.

Establishing a second association relationship between the information code and the identity of the electronic tag in the preparation phase of the composite packaging bag;

Obtaining a decryption key by verifying the identity information of the receiver, and verifying the legality of the decryption key according to the third association relationship. If the verification is passed, performing the step of reading the information in the electronic tag according to the decryption key ;

In this embodiment, the information code has a second association relationship with the identity of the electronic tag, and the validity of the second association relationship is verified by scanning the information code and the identity identifier, and the identity code and the decryption key of the information code and the electronic tag are There is a third association relationship, and the information code, the electronic tag and the decryption key are locked and associated to improve information security.

Further, the identity information of the consignee may be verified by the consignee's mobile phone or the APP registration user terminal, and the decryption key is obtained.

In this embodiment, the electronic label, the information code card and the auxiliary identification image located at different positions may constitute a special mark for distinguishing the composite packaging bag, and after identification, may be from the electronic label, the information code card and the auxiliary identification image. Obtaining a feature point separately, constructing a virtual triangle according to the plane coordinate position of the three feature points, and setting the positions of the electronic label, the information code card, and the auxiliary recognition image on each package are not completely the same, and thus the obtained virtual triangles are also different. Similarly, the spatial coordinates can be used as the original image fingerprint of the composite bag. Since the content of the acquired image is three-dimensional, the surface image of the composite bag is two-dimensional, and the plane coordinates obtained from the image need to be mathematically modeled. Transformation, the quantization matrix in the three-dimensional coordinate system and the two-dimensional coordinate system and their relative positional relationship are obtained, so that the original image fingerprint is more accurate.

It should be noted that there may be multiple feature points in the electronic tag, the information code card, and the auxiliary recognition image, and the points on different positions on the electronic tag, the information code card, and the auxiliary recognition image may be used as feature points, and thus may be combined. A variety of different virtual triangles.

Specifically, the process of acquiring image fingerprints includes traditional three-dimensional projection two-dimensional plane composition, computer virtual drawing, vector algorithm, two-dimensional vector matrix establishment and comparison, linear and nonlinear spatial analysis, and algorithm with certain fuzzy recognition ability. The algorithm is continuously optimized with the development and development of AI learning. The principle of the most basic surface image recognition judgment principle of the algorithm is explained:

1 framing and composition

1.1 Construction of three-dimensional model

When the packaging bag is shipped from the factory, the side of the packaging bag with the embedded RFID chip and the two-dimensional code printed with the auxiliary identification mark image is used as the modeling basis of the two-dimensional plane, and the printing coordinate system ruler is used as the auxiliary (the coordinate scale is one) The important function is to prevent the manual stretching of the bag by physical methods. Shooting the framing, first establish a two-dimensional coordinate system, and obtain the original image of the bag at this time;

1.1.1 Identifying element acquisition

1) When the package is used, the main elements are identified as an RFID chip, a two-dimensional code, an auxiliary recognition image, a head-up and a side-view image of the seal. In the captured image layer, as the first layer (surface layer) of the image layer.

2) Through the transparent packaging bag, the image of the package inside the bag is used as the second layer (inner layer) of the image layering in the captured image layer.

3) When the camera's DSP chip is framing, extract 1-3 frames of key images by drawing frames, and use the DSP chip's grid exposure technology to extract the digitized exposure of 1-3 frames of key frame images and digitize them to establish the original film data. material.

1.1.2 Element Separation and Vector Matrix Library Establishment

1) Through the digitization of the DSP grid exposure, in the coincidence enhancement of the 3-frame key frame, the key image feature point information is obtained, the consistent quantity is taken out, and the matching reference standard image feature library is compared and matched, and the acquisition is performed. The position of these image feature points on the target surface of the film.

2) Use these image feature points as key abstract points.

3) The target position image is also selected, and the first computer virtual composition is performed. The image is reconstructed by the framing DSP and the image is segmented. The image capture area is cut out by the image, and the computer divides the mesh equally. The element is the smallest separable unit of pixel resolution.

4) Defining the first position in the computer grid for the key abstract points, the two-dimensional coordinates as the first parameter library of the vector matrix, and establishing the random image classification plane 1 and the pairing vector library 1:

First point: XXXX, YYYY, 0

Second point: XABC, MNPQ, 0

The third point: and so on.........(Note: The letter indicates the vector value of the coordinate point)

5) The acquired coordinate axis image is extended by the continuous elements of the coordinates on both sides of the horizontal axis, and the lateral sides of the ordinate are extended to the boundary of the virtual composition image, and the target image negative film is cut into a subdivision mesh.

The coordinate axis and the reference standard coordinate are corrected, and the farthest point at both ends is used as the trimming edge of the corrected image bottom edge, and the larger image element of the intermediate coordinate axis is used as the reference object to establish the abstract ideal plane classification plane 2 and the pairing vector library 2 of the image. :

Among them, using the grid positioning of the key points in the classification plane 1 and the pairing vector library 1, in the computer-drawn flat coordinate system of the ideal plane classification plane 2, the coordinates of the key points of the virtual image elements are drawn to form an ideal vector library. 2:

First point: X1, Y1, 0

Second point: X2, Y2, 0

The third point: ......... and so on (Remarks: vector values and quadrants of X1, Y1 coordinate points)

6) The obtained vector library is selected by the pre-selection rule, and is exposed by the pre-judgment rule and the component at the exposure, filtering out the image layer portion Layer1 of the foreground surface layer bag, and the image portion Layer2 of the loaded goods, and then classifying the random image. 1 and the Layer 1 image element deletion in the pairing vector library 1, separating the image vector reduction matrix 3-1 paired by the Layer 2 and the random image classification plane 1;

Fifth point: XXXX, YYYY, 0

The ninth point: XABC, MNPQ, 0

The eleventh point: ......... and so on (note: the letter represents the vector value of the coordinate point)

And an image vector reduction matrix 3-2 paired by Layer 1 and the random image classification plane 1,

1.1.3 Simulation and Nonlinearization of 3D Image and Establishment of Vector Matrix Library

1) Image data of the bag edge sealing edge, extracting two key frame composite images from the side and the top, the processing is similar to 1.) 1) - 4), because the coordinate axis extends to the edge of the edge bag, on the side of the bag mouth The image is corrected by the angle of the software shooting angle, and the side image is converted (projected) into three image vector libraries by trigonometric operation:

In the positive plane image, the random image classification plane 1 and the paired vector library 1 are perpendicular to the random image classification plane 4 and the pairing vector library 4, and the image is drawn by the computer to the three-dimensional Z-axis, and the vector library 4 is:

The first point on the sealing side: 0, Y1, Z1

The second point on the sealing side: 0, Y2, Z2

The third point on the sealing side: ......... and so on

According to the predetermined rule, the image element reference points obtained by taking the seal edge of the seal are also stored in the vector library 4, and these reference points are random (and thus also non-linear).

Establish an abstract image of the ideal plane classification plane 5 and pairing vector library 5:

Similar process 1.1.2 of 5)

Filtering out the foreground surface layer image layer portion Layer1, and the loaded image portion Layer2, and then deleting the random image classification plane 4 and the Layer 1 image element in the paired vector library 4, leaving the Layer 2 and random image classification plane 4 The paired image vector reduction matrix 6-1 and the image vector reduction matrix 6-2 paired by Layer 1 and the random image classification plane 4.

2 image comparison

2.1 taking pictures

When the receiver takes a picture, take a picture through the mobile phone, follow the prompts to take pictures of the upper and side of the goods, and view the scene. In order to reduce the amount of calculation, first use the front image to generate the customer vector library to be compared, first with the ideal vector. The library 2 performs an alignment, and compares the corresponding coordinates of the vector library and the coordinate points according to a predetermined rule, and performs computer simulation drawing operations on the side length and the circumference of the triangle in which the points in the vector library matrix are planarly drawn, according to a predetermined rule. Suppose we first draw 1 triangle to get the offset matrix 7:

2.2 comparison

2.2.1 plane alignment

Similar

(original image drawing P1 – customer mobile viewfinder P1) / original image drawing P1

(original image drawing P2-client mobile viewfinder P2) / original image drawing P1

...

Wait for a series of comparisons, perform a predetermined formula operation with the coordinate axis difference, and obtain more triangles according to the predetermined parameters. The number of triangles of the batch is adjustable. For example, if the cumulative deviation of the batch triangle is within the control threshold, it can be judged as Positive similarity fitting, statistical voting by algorithm (controllable threshold), and then continue the two-dimensional comparison of the side sealing side, continue to judge the authenticity.

Generally, the two-dimensional alignment on both sides is successful in the first sampling period, and the algorithm can recognize the success of the item and stop the next operation. The algorithm can also be adjusted to perform all comparisons, including three-dimensional alignment, for panoramic judgment, which consumes a large amount of resources and consumes more comparison time.

Further, a parameter comparison dominated by the image vector reduction matrix 3-2 paired by the Layer 1 and the random image classification plane 1 may be performed; the cargo ratio dominated by the image vector reduction matrix 3-1 paired by the Layer 2 and the random image classification plane 1 Yes (Note: When the image vector parameter of layer1 is only compared with Layer1, Layer2 is only compared to this layer, that is, the package and the goods are aligned separately, and the positive alignment is linear at this time).

The more the level of comparison, the more blurred, and further, the average offset between Layer1 and Layer2 vector library can be established. The algorithm can be called simple fuzzy comparison or nonlinear alignment.

2.2.2 three-dimensional comparison

The three-dimensional comparison is more complicated, in which the Z-axis non-zero coordinate vector library on the sealing side is taken, and the coordinates of one side of the chip are compared between the banks, and the three-dimensional triangle is drawn. The principle is still computer space drawing, three-dimensional comparison operation. More complicated, the generated offset matrix is also more complicated. In the higher-order algorithm, volume calculation can also be substituted, and the volume matrix parameters are compared.

2.2.3 Comparison of goods

When the package contains goods, when it is packaged as a small package, the internal small parts will be displaced, and the image of layer2 will change. For the comparison of internal goods, the goods will be modeled first, and enter the identification object library. When identifying, the space vector angle fitting and projection will be performed through the corner points of the cargo position, and then the projection and modeling of multiple goods will be simulated. The projections are compared and then the volume calculation is performed. The algorithm is no longer described in detail, but the internal small displacement changes still do not affect the video comparison. Just in the judgment, when the package is recognized, the shape and initial form should try to capture the individual of the small internal goods as much as possible, and try not to miss the item. Otherwise, the result will be missing or unidentified objects. The information is then reviewed and judged.

2.3 judgment

If the continuous comparison is always judged to be a threshold with a very high similarity, the item is judged to be distorted by the statistical comparison between the vector matrices, and a judgment of non-conformity is given.

2.4 anti-stretching

If someone unpacks the package, in order to seal, and then use the physical means to lengthen the length of the plastic packaging bag, in the comparison, not only the naked eye can distinguish the scale distortion, it will be distorted when the vector library 1 is established, in the three-dimensional ratio The time must also be distorted and must be discovered.

The above description is only the simplest principle description of the algorithm. The actual algorithm is far more complicated than the above principle. The above explained principle ensures the feasibility of object video image recognition, and the reliability of the method described in this patent.

It should be noted that with the wide application of machine learning technology, optimized algorithms are introduced every few months, so the algorithm will be continuously optimized, and the description of the above principles will not limit the continuous algorithm optimization and upgrade. .

according to

Calculate the fitness;

In this embodiment, by using the spatial coordinate projection to the quantization matrix of the three-dimensional coordinate system and the two-dimensional coordinate system and the relative positional relationship thereof, the fitting degree between the original image fingerprint and the image fingerprint to be tested can be calculated, and the fitting degree is reached. When the preset value is used, it can be determined that the original image fingerprint is similar to the image fingerprint to be tested, that is, the composite packaging bag is the same packaging bag in the delivery phase and the receiving phase, and is not replaced.

Specifically, as shown in FIG. 8, the RFID chip, the two-dimensional code, and the auxiliary recognition image are identified from the surface image of the composite packaging bag, and a feature point is randomly acquired, and the coordinate is obtained by combining the coordinate system ruler; The acquisition rule may be determined according to different needs, for example, the auxiliary recognition image is an image of three square vertex dockings, and any one of the nine corner points in the auxiliary recognition image is acquired, and any of the four corner points of the edge of the two-dimensional code is obtained. One, in the circular epitaxial tangential intersection of the edge of the RFID tag (the circle is 4 points in the X-axis, 4 points in the Y-axis direction and 4 corners of the square formed by the tangent) anyone.

The virtual triangle is drawn with three feature points as three vertices, which is the original image fingerprint. According to the obtained feature points, the surface image can draw 288 different triangles of 9×4×8.

After the package arrives, first confirm whether there is physical damage to the package. If there is no damage, obtain the surface image of the package again, and extract N image fingerprints as the image fingerprint to be tested again;

The original image fingerprint is fitted and compared with the image fingerprint to be tested. If the fit of M of the N image fingerprints exceeds a preset threshold, the package is judged to be correct. N and M are preset natural numbers and N is greater than M. For example, N is 32 and M is 20, that is, as long as the fitting degree of 20 of the 32 image fingerprints to be tested exceeds a preset threshold, the package is judged to be correct. It is worth mentioning that the threshold can be preset or adjusted, and can also be learned through a self-learning algorithm.

When comparing the fitness with the threshold, compare the spatial parameters, including the projected three-sided length and perimeter of the spatial triangle formed by the spatial coordinates of the virtual triangle, as well as the spatial volume, cargo volume and morphological parameters, etc. If the degree of convergence is up to standard, it is judged that the fitting degree is successfully matched, and the fingerprint of the image to be tested is qualified; if there are M individual fingerprints in the N personality fingerprints, the package is judged to be correct.
