Embodiment 1
[0036] figure 2 It is a flowchart of a decoding method for determining a two-dimensional code according to an embodiment of the present invention. refer to figure 2 As shown, a decoding method for determining a two-dimensional code in this embodiment may include the following steps.
[0037] In step 202, each vertex of the two-dimensional code is determined.
[0038]In this step, the 4 vertices of the QR code can be determined. There are many ways to obtain the 4 vertices of the QR code. For example, you can first obtain the 4 sides of the QR code, and then use the 4 sides to obtain 4 vertices.
[0039] If the boundary of the two-dimensional code image is greatly disturbed, it will affect the positioning of the outer boundary of the two-dimensional code and cause recognition failure. At this time, the four vertices on the periphery of the two-dimensional code can be obtained through other methods of processing, and no examples are given here.

Embodiment 2
[0069] image 3 It is a flowchart of a decoding method for determining a two-dimensional code according to another embodiment of the present invention. refer to image 3 As shown, a decoding method for determining a two-dimensional code in this embodiment may include the following steps.
[0070] In step 302, each vertex of the two-dimensional code is determined.
[0071] In this step, the 4 vertices of the QR code can be determined. There are many ways to obtain the 4 vertices of the QR code. For example, you can first obtain the 4 sides of the QR code, and then use the 4 sides to obtain 4 vertices.
[0072] If the boundary of the two-dimensional code image is greatly disturbed, it will affect the positioning of the outer boundary of the two-dimensional code and cause recognition failure. At this time, the four vertices on the periphery of the two-dimensional code can be obtained through other methods of processing, and no examples are given here.
