[0070]In order to solve the existing problem that the terminal cannot recognize the two-dimensional code when there is more than one two-dimensional code in the image to be recognized acquired by the terminal, this embodiment provides a two-dimensional code recognition method. see image 3 , image 3 The basic flow chart of the two-dimensional code recognition method provided in this embodiment includes:
[0071] S301: When the image to be recognized containing at least two two-dimensional codes is collected, find out the FIP and the central picture of the two-dimensional code in the image to be recognized;
[0072] It should be understood that, in practical applications, there is a fault-tolerant mechanism for two-dimensional codes, so a picture of the center of the two-dimensional code can be placed in the middle of the two-dimensional code, for example, see Figure 4 The QR code shown. Since placing a picture in the middle of the two-dimensional code can make the two-dim...

[0113] This embodiment is based on the first embodiment, and further illustrates the present invention by taking a more specific two-dimensional code recognition process as an example.
[0114] see Figure 9 , Figure 9 It is a detailed flow chart of a two-dimensional code recognition method provided in the second embodiment of the present invention. The two-dimensional code recognition method includes:
[0115] S901: When an image to be recognized containing at least two two-dimensional codes is collected, search for a reference pattern in the image to be recognized that matches the standard FIP according to the pre-stored standard FIP;
[0116] S902: According to the black-and-white jumping rule of the two-dimensional code, for each found reference pattern, the center position of each reference pattern is used as the starting point to detect the horizontal direction and the vertical direction respectively;
[0117] S903: Determine the graphics satisfying the black-and-whit...

[0125] This embodiment also provides a two-dimensional code identification terminal, see Figure 10 As shown, it includes a processor 101, a memory 102 and a communication bus 103, wherein:
[0126] The communication bus 103 is used to realize connection and communication between the processor 101 and the memory 102;
[0127] The processor 101 is used to execute one or more programs stored in the memory 102, so as to realize the following steps:
[0128] When the image to be recognized containing at least two two-dimensional codes is collected, the FIP and the center picture of the two-dimensional code in the image to be recognized are found;
[0129] Obtain the location information of each FIP and the location information of each QR code center picture;
[0130] According to the position information of each FIP and each two-dimensional code center picture, respectively determine the detection pattern triplet corresponding to each two-dimensional code center picture;
