A two-dimensional code (2-dimensional bar code) is also called a two-dimensional bar code, and records data symbol information by using black and white specific geometric figures distributed according to a certain rule on a plane (two-dimensional direction); the concept of '0' and '1' bit streams forming the internal logic basis of a computer is skillfully utilized in code establishment, a plurality of geometric shapes corresponding to binary systems are used for representing character numerical value information, the information is automatically read by an image input device or a photoelectric scanning device so as to realize automatic information processing, and the two-dimensional bar code is widely applied to product packaging as an identification mark of product identity due to the following characteristics: 1. high density coding, large information capacity: can accommodate as many as 1850 capital letters or 2710 digits or 1108 bytes or more than 500 Chinese characters, and is about dozens of times higher than the capacity of the common bar code information; wide coding range: the two-dimensional bar code can encode digitalized information such as pictures, sounds, characters, signatures, fingerprints and the like; 3. the fault-tolerant ability is strong, has the error correction function: when the two-dimensional bar code is locally damaged due to perforation, dirt and the like, the two-dimensional bar code can be correctly read as is, and information can still be restored when the damaged area reaches 50%; 4. the decoding reliability is high: the decoding error rate is much lower than that of the common bar code, and the error rate does not exceed one million; 5. encryption measures may be introduced: the security and the anti-counterfeiting performance are good; 6. the cost is low, the manufacture is easy, and the durability is long; 7. the bar code symbol has variable shape, size and size proportion; 8. the two-dimensional bar code can be read using a laser or a CCD reader.
At present, the two-dimensional code is widely used in industry as an identifiable label, and plays a great role in promoting identity authentication of products and tracking of product sales, for example, basic information of products can be obtained by scanning the two-dimensional code on product packages; in modern logistics, a conveying path and the like of a product can be obtained by scanning a two-dimensional code on a product package. In order to enhance product quality control and quickly extract product production information and sales information, it is generally necessary to associate identification information of a product (for example, associating a two-dimensional code on the product with a code), and the existing method includes: after the product is packaged on the production line, the product is conveyed by the conveying device; in the conveying process, the code spraying device can sequentially spray codes on the products conveyed by the conveying device (wherein the codes comprise information such as product batch, production date, production place, production line and the like); the recognition device can sequentially read the two-dimensional codes on the product packages; and the correlation device performs correlation matching on the code spraying and the two-dimensional code on the same package, so that the correlation of the product identification information is realized. However, in the process of identifying and reading the two-dimensional code, the identifying and reading device may fail to identify and read, and the identifying and reading is invalid, so that the two-dimensional code of a certain product is not identified and the code-spraying information cannot be associated with the two-dimensional code information. At the moment, the common method is to trigger the removing device to remove the product which does not read the two-dimensional code, and the product cannot be normally listed at the moment, so that the product packaging and conveying production line cannot normally operate in serious conditions, and the benefit of a product manufacturer is damaged.

Fig. 1 is a flowchart of a first specific embodiment of a method for obtaining code information by calculating, according to a specific embodiment of the present invention, as shown in fig. 1, two-dimensional code information of a current product is calculated by using two-dimensional code information of adjacent products, so that the two-dimensional code information of the current product can be associated with code spraying information.
The specific embodiments shown in the drawings include:
step 101: and identifying the two-dimensional codes of the adjacent products on the packaging production line to obtain the two-dimensional code information of the adjacent products. The packaging production line packages the product, identifies the two-dimensional code on the product package, sprays the code on the product or the product package, associates the identified two-dimensional code information with the code spraying information, facilitates the authentication of the authenticity of the code spraying information on the product when a user scans the two-dimensional code, prevents lawbreakers from tampering the code spraying information and damaging the legitimate rights and interests of consumers, for example, illegal retailers tamper the code spraying of the production date of the product and enable overdue products to enter the market for sale again. The two-dimension code information is associated with the code spraying information, so that even if a lawbreaker tampers with the code spraying information, a consumer can obtain the real code spraying information of the product by scanning the two-dimension code on the product package, thereby preventing the lawbreaker from infringing the legal benefit of the consumer. However, due to the fact that the position of the two-dimensional code on the product package is not appropriate or the sensitivity problem of the code scanning device occurs, the two-dimensional code on the product package cannot be identified, and in order to enable the two-dimensional code information of the products to be associated with the code spraying information, the two-dimensional code of the adjacent product on the package production line can be identified, so that the two-dimensional code information of the current product can be obtained. In particular embodiments of the present invention, the products adjacent to the current product include products located in front of the current product and/or products located behind the current product.
Step 102: and calculating the position relation information between the current product and the adjacent product. Specifically, the information of the position relation between the current product and the adjacent product is calculated according to the size of the product and the conveying speed of the conveyor belt of the production line. The positional relationship information includes the distance between the center point of the current product and the center point of the adjacent product, the order of the current product and the adjacent product (i.e., which is before and which is after the current product and the adjacent product are conveyed), and whether the current product and the adjacent product are directly adjacent or indirectly adjacent (i.e., the positional relationship between the current product and the adjacent product, for example, the current product position is 22, the adjacent product position is 5, i.e., the 22 th product conveyed on the packaging line conveyor is the current product, the 5 th product conveyed on the packaging line conveyor is the adjacent product, the current product and the adjacent product are indirectly adjacent, and there are 16 products between). Since the product size and the conveying speed of the packaging line conveyor are known, information on the positional relationship between the current product and the adjacent product can be obtained.
Step 103: and searching the current two-dimension code information of the current product from a database according to the two-dimension code information and the position relation information. Because the sequence of the products on the packaging production line corresponds to the two-dimension code information stored in the database one by one, the two-dimension code information of the adjacent products and the position relation information between the adjacent products and the current product can be obtained, and then the two-dimension code information of the current product can be searched from the database.
Referring to fig. 1, the two-dimensional code information of the current product is calculated through the two-dimensional code information of the adjacent products, so that the two-dimensional code information of the current product is associated with the code spraying information, the identification and reading efficiency of the two-dimensional code information is improved, the rejection rate of the product is reduced, the legal benefit of a product producer is maintained, and the development of industry and commerce is promoted.
