in the present embodiment, the image processing unit of the signal processing module detects the number and width of the moire fringes of the first state image as shown in fig. 4 as the first moire parameter using the existing image detection algorithm, and the first moire parameter is recorded in the storage unit of the electronic single-pass ticket selling apparatus.
Step S240: comparing the first moire parameter with a set two-dimensional code moire fringe threshold value;
in this embodiment, it may be adopted that a corresponding threshold two-dimensional code image with fewer moire fringes is stored in a storage unit of the electronic single-way ticket selling device, as shown in fig. 5, a two-dimensional code image with moire fringes that are difficult to be distinguished by naked eyes is used as the threshold two-dimensional code image, and when the image is compared with the first state image according to an existing image algorithm, a comparison result, that is, the first state image has more moire fringes or less moire fringes than the threshold image, can be automatically obtained.
In other embodiments, the processor compares the first moire parameters extracted by the existing image algorithm with the moire parameters of the threshold two-dimensional code to obtain a comparison result, that is, the moire parameters of the first state image and the moire parameters of the threshold image are more or less than the number of moire fringes, and the moire fringe width is wider or narrower.
Step S250: outputting a first angle control signal according to the comparison result, wherein the first angle control signal controls the second screen to rotate on the plane where the second screen is located by a corresponding angle;
in the present embodiment, if the first state image and the threshold image have more moire fringes, the signal processing module outputs the first angle control signal to control the second screen to rotate 30-45 ° on the plane where the second screen is located. If the first state image and the threshold image have the same moire pattern, the rotation of the angle is not performed.
In other real-time examples, according to the comparison between the first moire parameter and the set two-dimensional code moire fringe threshold, if the first moire parameter has a larger number of moire fringes and/or a wider moire width than the set two-dimensional code moire fringe threshold, the signal processing module outputs the first angle control signal to control the second screen to rotate 30-45 ° on the plane where the second screen is located.
In addition, in order to more accurately reduce moire fringes of a two-dimensional code image which has undergone one rotation, as shown in fig. 6, an electronic single ticket selling method according to an embodiment of the present invention further includes the steps of:
step S300: generating a second state image according to the acquired relay signal;
wherein the second state is a state after the second screen is rotated.
