Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

In one embodiment, as shown in fig. 1, a method for generating a two-dimensional code is provided, where the two-dimensional code has a five-pointed star outer frame. The embodiment is illustrated by applying the method to a terminal, and it can be understood that the method can also be applied to a server, and can also be applied to a system comprising the terminal and the server, and is implemented by interaction between the terminal and the server. In this embodiment, the method includes the steps of:

And step 100, taking the central point of the pentagram outer frame as a circle center, and adopting different radiuses to make a plurality of circles.

For example, the sides of the five-pointed star frame are equal, and the degrees of each corner are equal. The radii of the plurality of circles decrease at a fixed unit distance in a direction from the outer ring to the inner ring within the pentagram outer frame.

Illustratively, referring to fig. 2, the center point O of the pentagram frame is the center of the circle, and the difference between the radii of the circumscribed circle a and the inscribed circle b of the pentagram frame is d. That is, the distance between the vertex of each corner of the pentagram outer frame and the point where the connection between the vertex of the corner and the center of the circle intersects the inscribed circle, that is, the length of the line segment CD in fig. 2 is d. A point P is selected on the segment CD, the length of the segment CP is 0.4d, and the length of the segment PD is 0.6 d. The length of the line segment PD is divided into 14 parts on average, and the fixed unit distance w is 0.6 d/14. And taking the central point O of the pentagram outer frame as the center of a circle and the length of the line segment PO as the radius to form a circumference, thereby obtaining the circumference with the largest inner radius of the angle. Taking the adjacent corner of the corner where the point C is located in fig. 2 as an example, the intersection point of the circle with the largest radius in the corner and the two sides of any one corner of the outer frame of the pentagram is A, B, and the length of the circular arc AB is 0.4 tan18 ° (0.4 tan18 ° (14/0.6) × w) (6 w). And (3) sequentially decreasing the radius from the length of the line segment PO by a fixed unit distance w by taking the point O as a circle center, making a plurality of circles until the circles coincide with the inscribed circle b, and then sequentially decreasing the radius from the radius of the inscribed circle b by a fixed unit distance w by taking the point O as a circle center to make three circles. There are 17 circles in the five-pointed star frame.

And 102, carrying out sub-lattice segmentation on the plurality of circumferences to obtain a plurality of sub-lattices in the pentagram outer frame.

The sub-lattices can be cut by using line segments in the five-pointed star outer frame to divide the plurality of circumferences into a plurality of small lattices, so that a plurality of sub-lattices are obtained. After obtaining a plurality of sub-lattices in the pentagram outer frame, the parts of the plurality of circumferences outside the pentagram outer frame can be deleted.

And step 104, taking every four circles as a group in the direction from the outer ring to the inner ring in the pentagram outer frame, determining sub lattices in the ring formed by the innermost two circles as separating sub lattices, and determining sub lattices in the two rings formed by the outermost three circles as information filling sub lattices.

The direction from the outer ring to the inner ring in the pentagram outer frame is the direction from the circumscribed circle a to the inscribed circle b in fig. 2. Taking four circles starting from the circle with the largest radius in the corner (i.e., the circle where the point P is located) as an example, the sub-lattices in the two rings formed by the outermost three circles including the circle where the point P is located are information filling sub-lattices, and the sub-lattices in the ring formed by the innermost two circles are separating sub-lattices. The padding subgrid is an area that can be used to pad the two-dimensional code information. The separator sub-lattice is not used to fill the two-dimensional code information.

And 106, filling data in the information filling sub-lattices to obtain the two-dimensional code.

And the data filled in the information filling sub-lattice is a two-dimensional code sequence obtained after the two-dimensional code information to be filled into the two-dimensional code is coded. Each set of two-dimensional code sequences consists of 8 binary digits. And filling the sub-lattices according to different binary digit filling information to obtain the two-dimensional code.

According to the two-dimensional code generation method, the two-dimensional code is provided with a pentagram outer frame, and a plurality of circumferences are made by taking a central point of the pentagram outer frame as a circle center and adopting different radiuses; carrying out sub-lattice segmentation on the plurality of circumferences to obtain a plurality of sub-lattices in the pentagram outer frame; taking every four circumferences as a group in the direction from the outer ring to the inner ring in the pentagram outer frame, determining sub lattices in a ring formed by the innermost two circumferences as separating sub lattices, and determining sub lattices in two rings formed by the outermost three circumferences as information filling sub lattices; and filling data in the information filling sub-lattice to obtain the two-dimensional code. The generation method of the two-dimensional code provided in the embodiment of the application can generate the pentagram-shaped two-dimensional code, enriches the generation mode of the two-dimensional code and the pattern of the two-dimensional code, and is suitable for not only the scene in which the square two-dimensional code is applied but also the scene in which the square two-dimensional code cannot be applied, for example: the method is suitable for the scene of the five-pointed star region in the seal, so that the application scene range is wider, and the applicability of the two-dimensional code is improved.

In one embodiment, the plurality of circles includes a first circle and a second circle, the first circle having a radius greater than a radius of the second circle. In step 102, as shown in fig. 3, sub-grid segmentation is performed on the plurality of circumferences to obtain a plurality of sub-grids within the five-pointed star outer frame, including:

step 300, aiming at any corner of the pentagram outer frame, performing sub-lattice segmentation on the first circumference based on a plurality of parallel first line segments with equal intervals to obtain a plurality of sub lattices, wherein the starting point of one of the first line segments is the central point of the first circular arc, the end point is the intersection point of the second line segment and the first circumference with the minimum radius, the second line segment is the line segment formed by the central point of the first circular arc and the circle center, and the first circular arc corresponds to the first circumference with the maximum inner radius of the corner.

For example, referring to fig. 4, the first circle with the largest corner inner radius is the circle where the point P is located, the first arc is the arc AB, and the central point of the first arc is the point P. The second line segment is a line segment OP formed by the center point P and the circle center O of the first circular arc. The first circumference with the smallest radius is the second circumference in the direction from the inner ring to the outer ring in the pentagram outer frame. The intersection of the second line segment and the first circle of smallest radius is point E. The starting point of one of the first line segments is point P and the end point is point E. The line segment PE is a first line segment. And taking the fixed unit distance w as a distance, and making a plurality of line segments parallel to the line segment PE to obtain a plurality of first line segments. At any angle of the pentagram outer frame, a plurality of first line segments are intersected and cut with the first circumference, so that a plurality of sub lattices can be obtained.

And 302, performing sub-lattice segmentation on the second circumference based on a plurality of third line segments to obtain a plurality of sub-lattices, wherein the starting point of each third line segment is the end point of each first line segment, the end point of each third line segment is the intersection point of each fourth line segment and the second circumference with the smallest radius, and each fourth line segment is the line segment formed by the end point of each first line segment and the circle center.

Illustratively, referring to FIG. 4, the second circle of smallest radius is the first circle c in the pentagram outer frame in the direction from the inner ring to the outer ring. Taking the first line segment with the end point as the point E as an example, the fourth line segment with the end point of the first line segment as the start point is the line segment EO. The intersection F of the line segment EO and the circumference c is the end point of one of the third line segments, and the starting point of the third line segment is the point E, i.e. the line segment ED is one of the third line segments. The method of the other line segments in the third line segment is the same as the method of the line segment ED, and is not described herein again.

And the third line segments are used for carrying out sub-lattice segmentation on the second circumference to obtain a plurality of sub-lattices. The interval of the plurality of sub lattices is w. At this time, the first circumference is all the circumferences (including the circumference at the point P and the circumference at the point E) from the circumference at the point P to the circumference at the point E, and the second circumference is the circumference at the point F, and obviously, the radius of the first circumference is larger than that of the second circumference.

It should be noted that the second circumference may include 1, 2, or 3 circumferences in the direction from the inner ring to the outer ring in the pentagram outer frame, and the second circumference is not specifically limited in this embodiment of the application.

In one embodiment, as shown in fig. 5, in step 106, performing data filling in the information filling sub-lattice to obtain a two-dimensional code, including:

and 500, coding the two-dimension code information to be filled to obtain a binary sequence.

In the embodiment of the present disclosure, the two-dimension code information of the two-dimension code generated by the computer may be numbers, letters, symbols, binary information, and the like. And determining the coding format according to the data type of the two-dimensional code information to be filled. For example, if the two-dimensional Code Information is both numeric and alphabetical, the two-dimensional Code Information is coded by ASCII (American Standard Code for Information exchange) to obtain a binary sequence, and if the two-dimensional Code Information includes chinese characters, etc., the two-dimensional Code Information is coded by UTF8 (8-bit, Universal Character Set/Universal Transformation Format) to obtain a binary sequence. The coded binary sequence takes 8 binary digits as a group, and if the number of the binary digits is less than 8, 0 is complemented. The two-dimensional Code may be implemented by introducing a reed-solomon error correction algorithm, and the implementation scheme of the error correction Code is consistent with the error correction Code of the existing QR Code (Quick Response Code, fast Response matrix graph Code), which is not described in detail in this application. The binary sequence after the introduction of the error correction code cannot exceed 20 groups. After the two-dimensional code information is coded, at most 20 groups of binary sequences are obtained, and if the number of the binary sequences is less than 20, the following two bytes are repeated: 11101100 and 00010001, until the two-dimension code information is coded to obtain 20 groups of binary sequences.

And 502, taking every four information filling sub-lattices in the field-character lattice as an information storage unit, and sequentially filling all binary digits in the binary sequence into the information storage unit to obtain the temporary code.

Wherein one information storage unit is filled with one binary digit. Different color blocks are filled in the information storage unit according to the difference of the binary digits. Every four information filling sub-lattices in the field-shaped lattice form one information storage unit, and a row of separating sub-lattices can be arranged between every two rows of information storage units, so that the information in the generated two-dimensional code is easier to read. It can be understood that the pentagonal frame is filled with color blocks in a grid pattern, the upper and lower layers of color blocks are separated by a ring (i.e. a row of separating sub-grid is separated between every two rows of information storage units), and each corner of the pentagonal frame (from the vertex of the corner to the inscribed circle b) can be filled with five layers of color blocks, and the number of each layer of information storage units is 3, 4, 5, 6 and 7 in sequence. In the area inside the pentagram frame but below each corner (from the inscribed circle b to the circle with the smallest radius inside the pentagram frame), one layer of color blocks may be filled, 7 color blocks may be filled in each layer (that is, the number of information storage units in each layer is 7), and 160 color blocks may be filled in the pentagram frame in total.

And sequentially filling all binary digits in the binary sequence into the information storage unit to obtain the temporary code. The time code is a two-dimensional code obtained after the two-dimensional code information is filled in all the information storage units in sequence. Temporary codes may have large areas of connected color blocks or spaces.

And step 504, performing mask processing on the temporary code to obtain a two-dimensional code.

Wherein, the Masking (Masking) process is an exclusive or (XOR) process of the temporary code by using the template code. The template code is shown in fig. 6, and the two-dimensional code finally obtained after the mask processing is performed by using the template code is shown in fig. 7. Exclusive-or (XOR) processing is to compare information storage units at the same position in the template code and the temporary code, and if binary digits filled in the information storage units of the template code and the temporary code are the same, the binary digits are 0, and if the binary digits are different, the binary digits are 1. For example, if the binary number filled in one information storage unit in the temporary code is 0, and the color of the filling is white (i.e., the filling is not performed), and if the binary number filled in the information storage unit at the same position in the template code is 1, and the color of the filling is black, the binary number filled in the information storage unit of the finally obtained two-dimensional code is 1, and the color of the filling is black. Or, if the binary digits filled in the information storage units at the same position in the template code are 0 and the color of the filling is white, the binary digits filled in the information storage units of the finally obtained two-dimensional code are 0 and the color of the filling is white. And removing the sub lattices and the circumferential lines of the finally obtained image through the mask processing to obtain the two-dimensional code. The mask processing avoids the two-dimensional code from generating large-area connected color blocks or blanks.

and aiming at three adjacent angles of the pentagram outer frame, respectively determining a first circle center on a connecting line between the vertex of the angle and the central point of the pentagram outer frame, respectively adopting a first radius as a third circumference, and filling colors in each third circumference to obtain the positioning mark.

For example, referring to fig. 8, in the middle angular position column, the line connecting the vertex of the corner and the center point of the pentagram outer frame is a line segment OC. A point G which is 0.3d away from the vertex C in the line segment OC is taken as a first circle center, and the first radius is 2 w. And taking the point G as the center of a circle, and making a circle with the radius of 2w as a third circle. Color filling each third circumference may result in a location mark.

The color of the third circumferential filling is not specifically limited, and the color of the third circumferential filling is different from the bottom color in the pentagram outer frame. The setting mode of the positioning marks in the other two corners of the adjacent three corners of the pentagram outer frame can be referred to the above mode, and details are not repeated in the embodiment of the application. The positioning marks in three adjacent corners of the pentagram outer frame can be used for positioning and marking the two-dimensional code.

In one embodiment, as shown in fig. 9, in step 502, sequentially filling each binary digit in the binary sequence into the information storage unit to obtain the time code, including:

step 900, based on the positioning mark, determining the start information storage unit filled by the binary sequence.

Wherein, three positioning marks are located in three adjacent corners of the five-pointed star outer frame, for example, as shown in fig. 8. And taking the middle corner as a starting corner and taking the information storage unit at the upper left corner in the starting corner as a starting information storage unit.

And step 902, filling the binary digits in the binary sequence into the information storage unit in sequence from the initial information storage unit.

Illustratively, referring to fig. 8, starting from the start information storage unit, information storage units in the row where the start information storage unit is located are filled with binary digits in a binary sequence from left to right. And after the filling of the information storage units in the row is finished, skipping the separation sub-lattices, sequentially filling from left to right from the leftmost information storage unit in the next row until all the information storage units in the corner where the initial information storage unit is located are filled, repeating the process in the second corner clockwise, and sequentially filling all the information storage units in the five corners of the five-pointed star outer frame.

Step 904, in the process of filling the binary digits in the binary sequence into the information storage unit, when the binary digit is 1, the information storage unit is filled with the first color, and when the binary digit is 0, the information storage unit is filled with the second color, so as to obtain the temporary code.

Illustratively, the bottom color inside the pentagram outer frame is white, the first color is black, the second color is white, and the positioning mark filling color is black. After the two-dimensional code information is coded, 20 groups of binary sequences are obtained, and the total number of the binary sequences is 160 binary digits. When the binary number filled in the information storage unit is 1, the information storage unit is filled with black, and when the binary number filled in the information storage unit is 0, the information storage unit is filled with white (or the information storage unit is not filled with the white), namely the information storage unit appears white). According to the filling sequence, filling is started from the initial information storage unit until all the information storage units in the pentagram outer frame are filled with 160 binary digits, and the time code is obtained. The two-dimensional code obtained by masking the temporary code is a pentagram-shaped starry two-dimensional code as shown in fig. 7.

The inner bottom color of the outer frame of the five-pointed star is red, the first color can also be white, the second color is red, and the filling color of the positioning mark is white. When the binary number filled in the information storage unit is 1, the information storage unit is filled with white, and when the binary number filled in the information storage unit is 0, the information storage unit is filled with red (or the information storage unit is not filled with red, namely the information storage unit is red). According to the filling sequence, filling is started from the initial information storage unit until all the information storage units in the pentagram outer frame are filled with 160 binary digits, and a time code is obtained. The two-dimensional code obtained by masking the temporary code is a pentagram-shaped yin two-dimensional code as shown in fig. 10. The yin-language two-dimensional code is more beautiful compared with the yang-language two-dimensional code.

The method for generating the two-dimensional code in the embodiment of the application can generate the pentagram-shaped two-dimensional code, so that the generation mode of the two-dimensional code and the pattern of the two-dimensional code are enriched, and the pentagram-shaped two-dimensional code can be suitable for not only a scene in which the square two-dimensional code is applied, but also a scene in which the square two-dimensional code cannot be applied, for example: the seal is suitable for scenes of five-pointed star areas in the seal, the seal can be combined, and in some certification business scenes, such as deposit certification, transaction certificates, contracts and other scenes, information related to the business scenes is added through the two-dimensional code on the premise of not influencing the overall attractiveness of the seal, so that the characteristic of being not falsifiable is improved. Therefore, the application scene range is wider, and the applicability of the two-dimensional code is improved.

It should be noted that, in the embodiment of the present application, the first color and the second color are not specifically limited, and all the methods that can generate the two-dimensional code of the present application are applicable to the embodiment of the present application.

Illustratively, the reading method of the two-dimensional code in the embodiment of the present application is an inverse operation of the two-dimensional code generation method. Firstly, reverse mask processing is carried out, namely, the two-dimensional code image is subjected to exclusive OR processing again, the two-dimensional code is restored into a temporary code, and a binary sequence in the information storage unit is obtained. And removing the complementary codes, namely removing the bytes supplemented by less than 20 groups of binary sequences after the original two-dimensional code information is coded and 0 supplemented by less than eight-bit binary digits in the binary sequences. And reading the information of the two-dimensional code, and verifying and correcting the information by combining with an error correcting code in the reading process to finally obtain a correct binary sequence of the two-dimensional code. And decoding the correct binary sequence of the two-dimension code to obtain the original information of the two-dimension code to be filled.

In one embodiment, the two-dimensional code includes an avatar placement area. The method for generating the two-dimensional code further comprises the following steps:

and taking the area in the circle with the smallest radius in the plurality of circles as an avatar placement area.

Wherein the area in the circle with the smallest radius does not contain the information filling sub-lattice and the separating sub-lattice.
