[0023] The following will describe in detail the specific implementation manners of the embodiments of the present invention with reference to the drawings. It should be understood that the specific implementation manners described herein are only used to illustrate and explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention.

[0024] Figure 1 is a flowchart of the trademark graphic code layout method provided by an embodiment of the present invention. As Figure 1 shown, the method includes:

[0025] Step S101: Determine the dot matrix code value, code system, and the shape and size of the image to be generated;

[0026] Specifically, in the embodiments of the present invention, a dot matrix code system that supports adjustable pixel density per unit area is used, preferably the microdot code. The microdot code is a highly robust sparse dot matrix code, which is a non-open-source encoding algorithm and decoding algorithm, and the code map cannot be recognized by other open-source code system decoding algorithms. Compared with traditional dense two-dimensional codes that convert the code value into binary 1 and 0 and arrange them in the form of dark and light code points respectively, there will be an obvious gap of at least 1 data position between the data obtained by converting the code value of the microdot code into binary. The code value can be a string of any character encoding. The shape of the image to be generated can be any regular image or an irregular image.

[0027] Step S102: Determine the mask of the image to be generated according to the shape and size of the image to be generated, and the mask of the image to be generated includes at least black, white, and gray;

[0028] Specifically, in order to directly display trademarks, LOGOs, and signs in the area where the product packaging or the body is spray-coded and maintain beauty, the trademarks, LOGOs, and signs to be displayed need to be integrated with the dot matrix code in one area, replacing the traditional solution of using one area for trademarks, LOGOs, and signs and separately coding a rectangular area, which is not beautiful and wastes the product surface space additionally. In the embodiments of the present invention, a mask needs to be set for the generated image. The shape and size of the mask are the same as those of the image to be generated, and the color distribution of the mask should be set corresponding to the image to be generated. Preferably, the mask includes at least black, white, and gray. The value corresponding to a black pixel is 0, the value corresponding to a white pixel is 255, and the value corresponding to a gray pixel is 1 - 254, as Figure 2 shown.

[0029] Step S103: Generate an original dot matrix code binary array according to the dot matrix code value, code system, and the shape and size of the image to be generated;

[0030] Specifically, in the embodiments of the present invention, according to the code value, a dot matrix code is generated through the encoding algorithm unique to the code system and converted into an original dot matrix code binary array, which is composed of "0" and "1". It can be understood that the dot matrix code is divided into several pixels of appropriate size. The value corresponding to a pixel with a dot is 1, and the value corresponding to a pixel without a dot is 0. The shape and size of the original dot matrix code binary array should be the same as those of the image to be generated. As Figure 3 shows a schematic diagram of the original dot matrix code binary array of an embodiment. For the convenience of clear presentation, Figure 3 only a simple binary array example is provided.

[0031] Step S104: Generate a synthesized array of graphic-code fusion according to the mask of the image to be generated and the original dot-code binary array, where the synthesized array of graphic-code fusion is a binary array.

[0032] Specifically, when the value corresponding to the pixel in the mask of the image to be generated is 0, the value corresponding to the pixel at the same coordinate in the synthesized array of graphic-code fusion is 1; when the value corresponding to the pixel in the mask of the image to be generated is 255, the value corresponding to the pixel at the same coordinate in the synthesized array of graphic-code fusion is 0; when the value corresponding to the pixel in the mask of the image to be generated is 1 - 254, the value corresponding to the pixel at the same coordinate in the synthesized array of graphic-code fusion is the value of the original dot-code binary array.

[0033] Step S105: Render pixels corresponding to different binary values in the synthesized array of graphic-code fusion with different colors to obtain the final dot-code image as the trademark graphic code.

[0034] Specifically, when the value corresponding to the pixel in the synthesized array of graphic-code fusion is 0, the pixel where 0 is located is not color-rendered; when the value corresponding to the pixel in the synthesized array of graphic-code fusion is 1, the pixel where 1 is located is color-rendered to obtain the final dot-code image as the trademark graphic code, as Figure 4 shown. Although Figure 4 it is rendered in black in the figure, if the ink used is CMYK color ink or spot color ink, or even invisible ink, the finally presented pattern can be a color-printed pattern.

[0035] Figure 5 is the structural block diagram of the trademark graphic code layout system provided by an embodiment of the present invention. As Figure 5 shown, the system includes: a code value size determination unit 1, a mask determination unit 2, an array generation unit 3, a fusion unit 4, and a rendering unit 5. Among them, the code value size determination unit 1 is used to determine the dot-code value, code system, and the shape and size of the image to be generated; the mask determination unit 2 is used to determine the mask of the image to be generated according to the shape and size of the image to be generated, and the mask of the image to be generated includes at least black, white, and gray; the array generation unit 3 is used to generate the original dot-code binary array according to the dot-code value, code system, and the shape and size of the image to be generated; the fusion unit 4 is used to generate a synthesized array of graphic-code fusion according to the mask of the image to be generated and the original dot-code binary array, where the synthesized array of graphic-code fusion is a binary array; the rendering unit 5 is used to render pixels corresponding to different binary values in the synthesized array of graphic-code fusion with different colors to obtain the final trademark graphic code.

[0036] Preferably, the value corresponding to the black pixel in the mask of the image to be generated is 0, the value corresponding to the white pixel is 255, and the value corresponding to the gray pixel is 1 - 254.

[0037] Preferably, the fusion unit 4 is further configured to: when the value corresponding to the pixel in the mask of the image to be generated is 0, generate a value corresponding to the pixel at the same coordinate of the synthesized array of graphic code fusion as 1; when the value corresponding to the pixel in the mask of the image to be generated is 255, generate a value corresponding to the pixel at the same coordinate of the synthesized array of graphic code fusion as 0; when the value corresponding to the pixel in the mask of the image to be generated is 1 - 254, generate a value corresponding to the pixel at the same coordinate of the synthesized array of graphic code fusion as the value of the original dot matrix code binary array.

[0038] Preferably, the rendering unit 5 is configured to: when the value corresponding to the pixel in the synthesized array of graphic code fusion is 0, no color rendering is performed on the pixel where 0 is located; when the value corresponding to the pixel in the synthesized array of graphic code fusion is 1, color rendering is performed on the pixel where 1 is located to obtain the final trademark graphic code.
