It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
It can be understood that, in most cases, the cashier opens the electronic device for the payer, scans most of the static two-dimensional codes provided by the merchant (in the process of manufacturing and image acquisition of the static payment image, impurities, interference and the like are inevitably mixed in the image, so that the image has the problems of noise, blurring and uneven gray scale), reads the information of the two-dimensional codes, and completes the payment operation. This operation leaves the security of the cash register questionable. Meanwhile, the merchant is also not convenient to replace the payment two-dimensional code at any time according to the needs, and the payment two-dimensional code does not have strong experience of application.
As shown in fig. 1, a schematic flow chart of a dynamic two-dimensional code generation method in an embodiment specifically includes the following steps:
In one embodiment, the method for generating a dynamic two-dimensional code according to the present disclosure further includes: when the mobile payment device is connected to the payment terminal device, the mobile payment device is started to initiate a connection request to the cloud server.
And step 102, if the connection is successful, the mobile payment equipment provides a payment terminal equipment request password input interface so that the merchant can input the payment terminal equipment request password.
103, when the mobile payment device receives a payment terminal device request password, sending a payment terminal device connection request signal to the cloud server, wherein the payment terminal device connection request signal at least comprises the payment terminal device request password;
and 104, when receiving a payment terminal device connection permission signal returned by the cloud server, the mobile payment device establishes data connection with the payment terminal device, wherein the cloud server returns the payment terminal device connection permission signal after successfully requesting password authentication for the payment terminal device.
And 105, in a preset time period, combining and configuring the received first step image, the received second step image and the received third step image through a preset algorithm. The payment image is composed of a first step image, a second step image and a third step image, wherein the first step image is used for specifying the position of the payment image, the second step image is used for distinguishing the two-dimensional code block from the background of the payment image, and the third step image is used for storing and receiving information sent by the cloud server.
And step 106, when the payment event is monitored for the combined and configured information, performing payment operation.
In an embodiment, it should be noted that, when a payment event is monitored for the information after the combined configuration, performing a payment operation includes: establishing a mapping relation between the characteristics of the cash register commodity and the price of the cash register commodity; according to the mapping relation, the commodity price in each commodity and the price of the commodity corresponding to the current payment image are obtained; and finishing the cash register operation according to the price of the commodity corresponding to the current payment image. And obtaining the commodity price of each commodity according to the mapping relation, accumulating the commodity prices, and obtaining the price of the commodity corresponding to the current payment image. It can be understood that the prices of the accumulated commodities are pre-stored, and the prices of the commodities can be quickly analyzed and obtained through neural network learning according to historical data of user shopping. It should be noted that, in order to increase the user experience, the data of the cash register operation and the completion status are displayed.
In one embodiment, the method for generating a dynamic two-dimensional code according to the present disclosure further includes: the method comprises the steps of obtaining the illumination intensity of a screen of the mobile payment device and the illumination intensity reflected by the screen of the mobile payment device in a preset time period, and constructing a screen illumination intensity database aiming at the mobile payment device and a screen reflection illumination intensity database aiming at the mobile payment device.
In addition, it should be noted that the dynamic two-dimensional code generation method according to the present disclosure further includes: intercepting the payment image after the combination configuration, and dividing the payment image; according to the Dajin algorithm, performing rough segmentation operation on the region of interest in the divided payment image; and completing the segmentation operation suitable for the payment image in the preset time period on the result obtained after the rough segmentation operation through shape testing.
The Otsu algorithm is to divide an original image into a foreground image and a background image by using a threshold. Specifically, the prospect is: points, mass moments and average gray levels of the foreground under the current threshold are represented by n1, csum and m 1; background: the number of points, the mass moment and the average gray level of the background under the current threshold are represented by n2, sum-csum and m 2. When the optimal threshold is taken, the difference between the background and the foreground is the largest, and the key is how to select a standard for measuring the difference, namely an Otsu algorithm, namely the maximum between-class variance, which is represented by sb, and the maximum between-class variance which is represented by fmax. Further, regarding the sensitivity of Otsu's algorithm to noise and target size, it only produces better segmentation effect on images with a single peak between classes variance. When the size ratio of the target to the background is very different, the inter-class variance criterion function may present double peaks or multiple peaks, which is not good, but the greater amount of algorithm is the least time-consuming. Further, the formula for the Otsu algorithm is derived as: recording t as a segmentation threshold of the foreground and the background, wherein the number of foreground points accounts for w0 of the image proportion, and the average gray level is u 0; the number of background points is w1 in the image scale, and the average gray scale is u 1. The total average gray scale of the image is: u-w 0 u0+ w1 u 1. The variance of the foreground and background images can be expressed by the following formula:
g (w 0 (u0-u) (u0-u) + w1 (u1-u) (u1-u) (w 0) w1 (u0-u1) (u0-u 1). It should be noted that the above formula is a variance formula. The formula for g can be referred to in probability theory, i.e. the expression for sb as described below. When the variance g is maximum, the difference between the foreground and the background at this time can be considered as maximum, and the gray level t at this time is the optimal threshold sb — w0 — w1 (u1-u0) (u0-u 1).
Specifically, the dividing the payment image includes: selecting a segmentation channel based on a statistical rule of payment image data of a training sample; selecting a segmentation threshold value in a segmentation channel, and performing foreground and background segmentation on the payment image; and carrying out communication area analysis according to the segmented foreground pixels and background pixels to obtain a qualified two-dimensional code area, wherein the payment image subblocks are divided in the qualified two-dimensional code area in a preset row and preset column dividing mode, and the preset row and the preset column are equivalent numerical values. Thereby providing the necessary data basis for subsequent rapid recognition of the payment image.
Further, it should be noted that, based on the statistical rules of the payment image data of the training sample, selecting the split channel includes: based on the statistical rules of the payment image data of the training samples, the distribution conditions of the image values in different color channels are obtained, and the color channel with the largest image value variance is obtained from the distribution conditions to form a segmentation channel. In addition, it should be further noted that selecting a segmentation threshold in a segmentation channel, and performing foreground and background segmentation on the payment image includes: obtaining a segmentation threshold value through a minimization algorithm in the Dajin algorithm; acquiring an image pixel value of a payment image; and performing dichotomy segmentation according to the image pixel value and the segmentation threshold value to obtain the foreground and the background. Further, it should be noted that, performing bisection segmentation according to the image pixel value and the segmentation threshold, and acquiring the foreground and the background includes: acquiring a region of which the image pixel value is higher than a segmentation threshold value as a foreground; and acquiring a region of which the image pixel value is lower than or equal to the segmentation threshold as a background.
Furthermore, performing connected region analysis according to the segmented foreground pixels and background pixels, and acquiring the two-dimensional code regions meeting the conditions includes: clustering the segmented foreground pixels and background pixels to form a communication area; and selecting the area with the largest size and meeting the prior position information in the communication area to form a two-dimensional code area meeting the conditions, and outputting the two-dimensional code area meeting the conditions. Further, it should be noted that the performing, by shape testing, the segmentation operation applicable to the payment image on the result obtained after the rough segmentation operation includes: and completing the graph segmentation operation suitable for the payment image according to the result obtained after the rough segmentation operation through an area test, wherein the area test is to judge whether the number of the pixel points in the region of interest meets a pixel point threshold interval of a preset normal two-dimensional code area. Furthermore, it should be noted that the completing, by the shape test, the segmentation operation applicable to the payment image on the result obtained after the rough segmentation operation includes: completing the graph segmentation operation suitable for the payment image by a simple malformation degree calculation formula gamma l/N on the result obtained after the rough segmentation operation through a malformation degree testpCalculating the degree of deformity of the region of interest, wherein l is the perimeter of the region of interest, and N ispThe number of pixel points in the region of interest is counted; presetting a high threshold gamma of degree of deformityT(ii) a When gamma is less than or equal to gammaTJudging that the result obtained after the rough segmentation operation passes the deformity degree test; when gamma > gammaTIn time, a segmentation method based on a gradient vector flow-active contour model carries out secondary rough on the region of interestAnd performing segmentation operation, and completing the segmentation operation suitable for the payment image through shape testing on the result obtained after the secondary rough segmentation operation.
