Description

A generation method, recognition method, recognition device and system of a fluorescent three-dimensional code

technical field

The invention relates to the technical field of three-dimensional code information, in particular to a method for generating a fluorescent three-dimensional code, a recognition method, a recognition device and a system.

Background technique

Identification codes have gone through the development process of barcodes, two-dimensional codes and three-dimensional image codes.

A barcode is a graphic identifier that arranges multiple black bars and white spaces with different widths according to certain coding rules to express a set of information. By connecting with the database on the network, it displays the information of the product corresponding to the barcode. A common barcode is a parallel line pattern formed by black bars (abbreviated as bars) and white bars (abbreviated as empty) with very different reflectivity. Barcodes can be connected to the database to mark the country of production, manufacturer, product name, production date, book classification number, mail start and end location, category, date, etc. It has been widely used in many fields. However, a single-dimensional barcode only expresses information in the horizontal direction, but does not express any information in the vertical direction, and its height is usually for the alignment of the reader.

Two-dimensional code, also known as two-dimensional barcode, two-dimensional barcode was first invented in Japan. It is a black and white graphic that is distributed in a plane (two-dimensional direction) according to certain rules to record data symbol information. In the compilation, the concept of "0" and "1" bit streams that constitute the internal logic basis of the computer is cleverly used, and several geometric shapes corresponding to binary are used to represent the text and numerical information codes, which are automatically recognized by image input devices or photoelectric scanning devices. Read for automatic processing of information. With the wide application of two-dimensional codes, people have further requirements for information storage and information processing of barcodes. The solutions to increase the barcode size or increase the barcode density have their limitations: increasing the barcode size requires a larger printing area provided by the barcode carrier; increasing the barcode density requires printing equipment and reading equipment in terms of accuracy There are higher requirements, and it will reduce the anti-interference ability of the barcode, which greatly limits the use environment of the barcode.

In order to solve these problems, the two-dimensional barcode is extended, and a new barcode—three-dimensional code is proposed. The three-dimensional code is based on the two-dimensional code to add a dimension to carry information and increase the information capacity of the barcode. The most common type of three-dimensional code uses color as the information carrier of the third dimension. It applies color coding on the basis of traditional barcodes, and expresses data information through different color combinations. It has the code structure of two-dimensional barcodes, but its information density is much higher than that of two-dimensional barcodes of the same size.

However, color is the third-dimensional information carrier of the 3D code, and the information carrier has a single form; the data information is represented by combined colors, which makes the data capacity limited, and the combined colors may have unclear boundaries, resulting in data information errors , Information security and reliability are poor, thus affecting the scope of use of the three-dimensional code.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

The purpose of the present invention is to provide a method for generating a fluorescent three-dimensional code, by printing a two-dimensional code and a third-dimensional fluorescent array with fluorescent materials on a two-dimensional plane matrix, so that the third-dimensional fluorescent array and the two-dimensional code overlap The plan view of the fluorescent three-dimensional code is formed, and three-dimensional codes with different fluorescent materials can be obtained according to the needs, and the data capacity is large; the fluorescent signal in the fluorescent three-dimensional code needs to be excited by laser, which can ensure the safety and reliability of the information.

Among them, molecules in a substance are excited to form molecules in an excited state after absorbing external photons, and need to lose energy through various ways when returning to the ground state. This process is called relaxation. In many cases, when the molecule returns to the ground state, energy is lost to the surroundings in the form of heat. However, in some cases, the energy can be released in the form of fluorescence to form a fluorescent signal, and the corresponding substance is called a fluorescent material.

Specifically, the molecules that are excited from the electronic ground state to the vibration levels in the first electronic excited state generally lose part of their energy in some form (collectively referred to as internal conversion). energy level and even return from a higher electronically excited state such as the second electronically excited state to the lowest vibrational energy level of the first electronically excited state. This process is about 10 ^-12 seconds. From the lowest vibrational energy level of the first electronically excited state back to the different vibrational energy levels of the ground state, if the energy is released in the form of photons, the emitted light is called fluorescence. This process usually occurs within 10 ^-6 -10 ^-9 seconds, which is fast.

In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, the generation method of fluorescent three-dimensional code of the present invention comprises:

Step 100: Provide a carrier with a two-dimensional planar matrix.

Step 110: Print out a two-dimensional code on the two-dimensional plane matrix of the carrier.

Step 120: Add fluorescent materials to the printed ink, and print a third-dimensional fluorescent array in the two-dimensional plane matrix before or after printing the two-dimensional code, so that the third-dimensional fluorescent array and the two-dimensional code overlap to form a fluorescent three-dimensional code floor plan.

The carrier of the two-dimensional plane matrix is paper or plastic, and the fluorescent three-dimensional code produced by the method for generating the fluorescent three-dimensional code of the present invention is generally printed on the surface of paper, plastic and other materials by printing. Fluorescent ink is formed by adding fluorescent materials in printing, which has the property of converting short-wave ultraviolet light into longer visible light and reflecting more dazzling colors. The fluorescent ink is excited by ultraviolet light (200-400nm) Special inks that emit visible light (400-800nm), also known as ultraviolet fluorescent inks. According to different excitation wavelengths, it can be divided into short-wave and long-wave. The excitation wavelength of 254nm is called short-wave ultraviolet fluorescent ink, and the excitation wavelength of 365nm is called long-wave ultraviolet fluorescent ink. According to the change of color, it is divided into three types: colorless, colored, and color-changing. Colorless can display red, yellow, green, Blue and other colors; colored can make the original color shine; discolored can change one color into another color.

Due to the short time for emitting fluorescent signals, in order to avoid affecting the recognition of the two-dimensional code and the third-dimensional fluorescent array, the third-dimensional fluorescent array is generally printed in the two-dimensional plane matrix after printing the two-dimensional code, so that the third dimension A fluorescent array overlays a QR code.

Wherein, the encoding of the fluorescent three-dimensional code includes two-dimensional code encoding and third-dimensional fluorescent array encoding, and the two-dimensional code encoding method includes digital encoding and character encoding.

Among them, the digital encoding: from 0 to 9, if the number of digits to be encoded is not a multiple of 3, then the last remaining 1 or 2 digits will be converted into 4bits or 7bits, then every other 3 digits The numbers will be encoded into 10bits, 12bits, 14bits, and the length of the encoding is determined by the length of the third-dimensional fluorescent array.

For example, under the size of Version 1 and the error correction level is H, code: 01234567; divide the above numbers into three groups: 012 345 67; convert them into binary: 012 into 0000001100; 345 into 0101011001; 67 Convert to 1000011. Then string these three binary numbers together: 0000001100 0101011001 1000011. Convert the number of numbers into binary (version 1-H is 10bits): the binary number of 8 numbers is 0000001000; add the sign 0001 of the digital code and the code of step 4 to the front: 0001 0000001000 0000001100 0101011001 1000011.

The character code: including 0-9, uppercase A to Z (no lowercase), and symbols "$", "%", "*", "+", "-", ".", "/", ":" and "space". These characters will be mapped into a character index table (as shown in Figure 2, where SP is a space, Char is a character, and Value is its index value). The process of character encoding is: first group the characters in pairs, then convert them into 45 base as shown in Figure 2, and then convert them into 11bits binary, if there is a single one at the end, then convert it into 6bits binary . The encoding mode and the number of characters need to be compiled into 9, 11 or 13 binary numbers according to different Version sizes.

For example, under the size of Version 1 and the error correction level is H, the encoding: AC-42:

First, find the index (10, 12, 41, 4, 2) of the five entries of AC-42 from the character index table; second, group by two: (10, 12) (41, 4) (2) ;Third, convert each group into 11bits binary: (10,12)10*45+12 equals 462 into 00111001110, (41,4)41*45+4 equals 1849 into 11100111001, (2) equals 2 into 000010; Fourth, connect these binary numbers: 00111001110 11100111001 000010.

The encoding method of the third-dimensional fluorescent array is as follows:

Code according to the scanner equipped with filters. For example, fluorescent ink emits different colors of fluorescence, and a red filter is installed on the scanner, the scanner can only receive red light signals, and the scanner receives red light signals at this point. The light signal is expressed as a binary "1", and the point that does not receive a red signal is expressed as a binary "0". The arrangement and combination of the points determines the meaning represented by the fluorescent part. And its number code and character code are the same as those of the above-mentioned basic two-dimensional code.

For example, after completing the above steps 1-4 in the character encoding of the QR code, encode the information of 0011100111011100111001 000010 into the base QR code, and convert the number of characters into binary (9 bits for Version1-H) : 5 characters, 5 is converted into 000000101; the code identification is 0010, code 0010 and the number of characters into the fluorescent part of the fluorescent code. When the base QR code and the fluorescent part are integrated, it is the complete code of the data: 0010000000101 00111001110 11100111001 000010. The space occupied by the same information carried on the fluorescent three-dimensional code will be greatly reduced.

Step 330: Arranging and combining the two-dimensional data code and the third-dimensional data code to obtain information represented by the fluorescent three-dimensional code.

The placement of colorless fluorescent ink does not affect the information reading of ordinary two-dimensional codes, and does not change the information storage of the original two-dimensional codes, but the colorless fluorescent ink will emit different colors of fluorescence when excited by laser light, which can display red, yellow and green , blue and other colors, the different alternating ways of each color can be a mode of information storage, with a large amount of information.
