Example Embodiment
[0064] See figure 2 An embodiment of the present application provides a method for correcting distortion of a two-dimensional code, and the method includes the following steps:
[0065] Step S101: Obtain a two-dimensional code image.
[0066] In specific implementation, the QR code image scanned by the code scanning tool can be obtained on the computer, or the QR code image can be directly obtained by the device that collects the QR code image.
[0067] Step S102: Calculate the distortion 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 deformed, The coordinates of the four vertices of the quadrilateral are ca...
