图1为本发明实施例中的二维码的编码方法的流程示意图。FIG. 1 is a schematic flowchart of a method for encoding a two-dimensional code in an embodiment of the present invention.
图2为本发明实施例中的分配策略的示意图。Fig. 2 is a schematic diagram of an allocation strategy in an embodiment of the present invention.
具体实施方式Detailed ways
为使本发明的技术方案及优点更加清楚明白，以下结合附图及具体实施例，对本发明作进一步详细的说明。In order to make the technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
图1为本发明实施例中的二维码的编码方法的流程示意图。如图1所示，本发明实施例中的二维码的编码方法包括：FIG. 1 is a schematic flowchart of a method for encoding a two-dimensional code in an embodiment of the present invention. As shown in Figure 1, the coding method of the two-dimensional code in the embodiment of the present invention comprises:
步骤11，对携带有防伪信息的需编码信息进行编码，生成具有多个图像帧的二维码序列。Step 11: Encode the information to be encoded carrying the anti-counterfeit information to generate a two-dimensional code sequence with multiple image frames.
在本步骤中，将先对需编码信息进行编码，其中，所述需编码信息中携带有防伪信息。进行上述编码后，即可得到具有多个图像帧的二维码序列。In this step, first encode the information to be encoded, wherein the information to be encoded carries anti-counterfeit information. After the above encoding is performed, a two-dimensional code sequence with multiple image frames can be obtained.
在本发明的技术方案中，可以使用多种方法对需编码信息进行编码。例如，可以使用现有技术中常见的编码技术进行编码，本发明对此不做限制。In the technical solution of the present invention, various methods can be used to encode the information to be encoded. For example, common coding techniques in the prior art may be used for coding, which is not limited in the present invention.
步骤12，根据预设的分配策略，设置二维码序列中的各个图像帧的分辨率，使得所述二维码序列中至少有两个图像帧具有不同的分辨率。Step 12: Set the resolution of each image frame in the two-dimensional code sequence according to a preset allocation strategy, so that at least two image frames in the two-dimensional code sequence have different resolutions.
在现有技术中，二维码被印刷出来后，很容易被人复制，从而难以防伪。因此，在本发明的技术方案中，在步骤11中得到编码后的具有多个图像帧的二维码序列之后，并不是直接输出该二维码序列，而是先对该二维码序列中的各个图像帧的分辨率进行设置，使得该二维码序列中至少有两个图像帧具有不同的分辨率。In the prior art, after the two-dimensional code is printed, it is easy to be copied, so it is difficult to prevent counterfeiting. Therefore, in the technical solution of the present invention, after obtaining the coded two-dimensional code sequence with multiple image frames in step 11, the two-dimensional code sequence is not directly output, but the two-dimensional code sequence in the two-dimensional code sequence is first The resolution of each image frame is set so that at least two image frames in the two-dimensional code sequence have different resolutions.
在本发明的技术方案中，可以使用多种预设的分配策略，设置二维码序列中的各个图像帧的分辨率。以下将以其中的几种具体实现方式为例，对本发明的技术方案进行详细的介绍。In the technical solution of the present invention, multiple preset allocation strategies can be used to set the resolution of each image frame in the two-dimensional code sequence. The technical solution of the present invention will be described in detail below by taking several specific implementation manners as examples.
例如，较佳的，在本发明的具体实施例中，所述预设的分配策略为：For example, preferably, in a specific embodiment of the present invention, the preset allocation strategy is:
根据印刷技术支持的分辨率的级数，为二维码序列中的每个图像帧指定相应的分辨率。According to the series of resolutions supported by the printing technology, specify the corresponding resolution for each image frame in the two-dimensional code sequence.
例如，较佳的，在本发明的具体实施例中，所述印刷技术支持的分辨率的级数为四个级数：128×128、256×256、512×512和1024×1024。For example, preferably, in a specific embodiment of the present invention, the resolution series supported by the printing technology is four series: 128×128, 256×256, 512×512 and 1024×1024.
图2为本发明实施例中的分配策略的示意图。如图2所示，当印刷技术支持的分辨率的级数为上述4个级数，且二维码序列中的具有4个图像帧时，此时分辨率的级数与二维码序列中图像帧的数量相等，因此可以有多种分配策略。Fig. 2 is a schematic diagram of an allocation strategy in an embodiment of the present invention. As shown in Figure 2, when the resolution series supported by the printing technology is the above four series, and there are four image frames in the two-dimensional code sequence, the resolution series at this time is the same as that in the two-dimensional code sequence The number of image frames is equal, so multiple allocation strategies are possible.
例如，如图2中的(a)所示，可以按照分辨率的级数从大到小的顺序，依次为每个图像帧设置不同的分辨率。For example, as shown in (a) in FIG. 2 , different resolutions may be sequentially set for each image frame in descending order of resolution series.
例如，如图2中的(b)所示，也可以按照分辨率的级数从小到大的顺序，依次为每个图像帧设置不同的分辨率。For example, as shown in (b) in FIG. 2 , it is also possible to set different resolutions for each image frame sequentially in ascending order of resolution series.
例如，如图2中的(c)、(d)所示，也可以按照随机的分配方式或其他的预设分配方式，依次为每个图像帧设置不同的分辨率。在此不再赘述。For example, as shown in (c) and (d) in FIG. 2 , different resolutions may be sequentially set for each image frame according to a random distribution method or other preset distribution methods. I won't repeat them here.
另外，在本发明的技术方案中，当分辨率的级数与二维码序列中图像帧的数量不相等时，也可以有多种分配策略。In addition, in the technical solution of the present invention, when the series of resolutions is not equal to the number of image frames in the two-dimensional code sequence, there may be multiple allocation strategies.
例如，当分辨率的级数N小于二维码序列中图像帧的数量M时，可以为二维码序列中的前N个图像帧依次设置不同的分辨率，然后将剩余的(M-N)个图像帧均设置为指定的分辨率(例如，最大的分辨率或最小的分辨率或其它指定的分辨率)。另一种方式是：随机的选择二维码序列中的N个图像帧，对随机选择的N个图像帧依次设置不同的分辨率，然后再将剩余的(M-N)个图像帧均设置为指定的分辨率。除此之外，还可以使用其它的分配策略，本发明对此并不做限定。For example, when the resolution series N is less than the number M of image frames in the two-dimensional code sequence, different resolutions can be sequentially set for the first N image frames in the two-dimensional code sequence, and then the remaining (M-N) The image frames are all set to a specified resolution (eg, maximum resolution or minimum resolution or other specified resolution). Another way is: randomly select N image frames in the two-dimensional code sequence, set different resolutions for the randomly selected N image frames in turn, and then set the remaining (M-N) image frames to the specified resolution. In addition, other allocation strategies may also be used, which is not limited in the present invention.
再例如，当分辨率的级数N大于二维码序列中图像帧的数量M时，可以先从N个分辨率的级数中选择M个级数(例如，按照从小到大的顺序进行选择、按照从大到小的顺序进行选择或随机选择等)，然后为二维码序列中的M个图像帧依次设置不同的分辨率。除此之外，也还可以使用其它的分配策略，本发明对此并不做限定。For another example, when the resolution series N is greater than the number M of image frames in the two-dimensional code sequence, you can first select M series from the N resolution series (for example, select from small to large , according to the order from large to small or randomly selected, etc.), and then sequentially set different resolutions for the M image frames in the two-dimensional code sequence. In addition, other allocation strategies may also be used, which is not limited in the present invention.
步骤13，输出所述设置分辨率后的二维码序列。Step 13, outputting the two-dimensional code sequence with the set resolution.
另外，在本发明的技术方案中，上述的二维码可以是汉信码，也可以是其它的二维码。In addition, in the technical solution of the present invention, the above-mentioned two-dimensional code may be a Chinese Xin code, or other two-dimensional codes.
通过上述的步骤11～13，即可得到设置了分辨率的二维码序列。由于在上述设置了分辨率的二维码序列中，各个图像帧的分辨率是不同的，而且有的图像帧的分辨率很小，因此对于普通用户来说，由于其并不知道各个图像帧的分辨率的大小，因此如果不使用特殊的读取装置，则很难有效地复制上述的二维码序列，难以进行伪造。Through the above steps 11-13, the two-dimensional code sequence with the resolution set can be obtained. Since in the above-mentioned two-dimensional code sequence with resolution set, the resolution of each image frame is different, and the resolution of some image frames is very small, so for ordinary users, since they do not know the resolution of each image frame Therefore, it is difficult to effectively copy the above-mentioned two-dimensional code sequence without using a special reading device, and it is difficult to forge.
在读取上述设置了分辨率的二维码序列时，由于读取装置的分辨率足以读取印刷技术所支持的各种分辨率，特别是能够读取印刷技术所支持的最小的分辨率，因此可以有效地识别出上述二维码序列中的各个图像帧，以读取其中所携带的防伪信息，从而能够有效地实现防伪。When reading the above-mentioned two-dimensional code sequence with a resolution set, since the resolution of the reading device is sufficient to read various resolutions supported by the printing technology, especially the smallest resolution supported by the printing technology, Therefore, each image frame in the above-mentioned two-dimensional code sequence can be effectively identified to read the anti-counterfeiting information carried therein, thereby effectively realizing anti-counterfeiting.
综上所述，在本发明的技术方案中，由于先对携带有防伪信息的需编码信息进行编码，生成具有多个图像帧的二维码序列，然后再根据预设的分配策略，设置二维码序列中的各个图像帧的分辨率，使得所述二维码序列中至少有两个图像帧具有不同的分辨率，从而使得最终所输出的二维码序列中的各个图像帧具有不同的分辨率，一般用户如果不使用特殊的读取装置，将难以完全读取该二维码序列中的各个图像帧，从而难以完成复制并进行伪造，因而可以有效地提高二维码的防伪性能。To sum up, in the technical solution of the present invention, since the information to be encoded that carries the anti-counterfeiting information is encoded first, a two-dimensional code sequence with a plurality of image frames is generated, and then according to the preset distribution strategy, two-dimensional code sequences are set. The resolution of each image frame in the two-dimensional code sequence, so that at least two image frames in the two-dimensional code sequence have different resolutions, so that each image frame in the final output two-dimensional code sequence has a different If the general user does not use a special reading device, it will be difficult to completely read each image frame in the two-dimensional code sequence, making it difficult to complete copying and forgery, thus effectively improving the anti-counterfeiting performance of the two-dimensional code.
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明保护的范围之内。The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the present invention. within the scope of protection.
