Embodiment Construction
[0064] see figure 2 , the embodiment of the present application provides a two-dimensional code distortion correction method, the method includes the following steps:
[0065] Step S101, acquiring a two-dimensional code image.
[0066] During specific implementation, the two-dimensional code image scanned by the code scanning tool can be obtained on the computer, or the two-dimensional code image can be directly obtained by using the device for collecting the two-dimensional code image.
[0067] Step S102, calculating the distorted image coordinates p of the four vertices of the two-dimensional code image according to the two-dimensional code image.
[0068] In this step, the distorted image coordinates p of the four vertices of the two-dimensional code image refer to the coordinates of the four vertices of the quadrilateral formed by the edges of the two-dimensional code image. Since the quadrilateral is obtained after the two-dimensional code image is distorted, therefore ...
