Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0017] Embodiment 1

[0018] Please refer to Figure 1 - Figure 2 As shown, the present invention is a cross-border e-commerce electronic data management system based on big data, including; A commodity data acquisition module, which is used to acquire the click volume and corresponding sales volume data respectively corresponding to each commodity of the same type as the commodity to be launched in the area to be launched; A calibrated commodity acquisition module analyzes the click volume and corresponding sales volume data respectively corresponding to each commodity of the same type as the commodity to be launched in the area to be launched, and marks the calibrated commodity of the commodity to be launched according to the analysis result. The specific method is as follows: Mark the click volume and corresponding sales volume values respectively corresponding to each commodity of the same type as the commodity to be launched in the area to be launched as DAi and DBi, where i represents different commodities, i is a positive integer, and i≥1; Mark the sum of the products of the click volume DAi and sales volume value DBi of each commodity and the fixed parameter coefficients θ1 and θ2 respectively as the preferred coefficient Xi corresponding to each commodity, that is, through the formula: Xi = DAi×θ1 + DBi×θ2, calculate the preferred coefficient Xi corresponding to each commodity. The specific values of the fixed parameter coefficients θ1 and θ2 are determined by relevant personnel according to actual needs, satisfying 1 = θ1 + θ2 and θ2>θ1; Mark the commodity with the preferred coefficient Xi value greater than the preset preferred threshold Y1 as the calibrated commodity of the commodity to be launched. Otherwise, no processing is performed. The specific value of the preset preferred threshold Y1 is determined by relevant personnel according to actual needs; By comprehensively considering the click volume and sales volume data of the same type of commodities in the area to be launched, and combining the fixed parameter coefficients to calculate the preferred coefficient, it is possible to more accurately mark the calibrated commodities of the commodities to be launched, improve the accuracy of the selection of the calibrated commodities for the commodities to be launched, provide a more reliable basis for subsequent main image analysis and launch decision-making, solve the problem of inaccurate calibration caused by relying only on a single indicator to determine popular commodities, enable the commodities to be launched to have a more targeted reference object, and improve the accuracy of market positioning.

[0019] An image data acquisition module acquires the image data of the main images of the calibrated commodities respectively corresponding to the area to be launched; An image analysis module is used to segment the image data of the main images of the calibrated commodities respectively corresponding to the area to be launched, obtain the image region blocks of each main image, obtain the channel values corresponding to the red, green, and blue channels of each pixel point in each image region block through the RGB color model and analyze them, and then obtain the red, green, and blue channel reference values of each image region block; Through the image segmentation unit, the main product images corresponding to each calibrated product are evenly segmented into multiple image region blocks; Through the image region data analysis unit, the channel values corresponding to the red, green, and blue channels respectively corresponding to each pixel point in the image region blocks of each main product image are analyzed, and then the red channel reference value, green channel reference value, and blue channel reference value corresponding to each image region block are obtained. The specific method is as follows: A1: Randomly select one from multiple image region blocks as the target region block; A2: Randomly select one from each main product image as the target image; For each pixel point in the target region block of the obtained target image, through the RGB color model, the channel values corresponding to the red, green, and blue channels respectively corresponding to each pixel point in the target region block are obtained; Select the red channel from the red, green, and blue channels as the analysis channel, obtain the red channel values corresponding to each pixel point in the target region block, and mark them as He respectively, where e represents different pixel points in the target region block, e = 1, 2,..., a, where a represents the number of pixel points in the target region block, a is a positive integer, a ≥ 1; Through the formula: , obtain the discrete value W of the red channel value He corresponding to each pixel point in the target region block, where Hj is any one of He, Hp is the mean value of He, a ≥ j ≥ 1; And analyze the discrete value W. When the discrete value W is less than the preset value Y2, then take the mean value Hp of He as the red channel calculation value E1 corresponding to the target region block of the target image. When W is greater than or equal to the preset value Y2, then delete the values with larger deviations from the mean value Hp among them in ascending order according to the values of He, and record the number of deleted values as r. At the same time, recalculate the discrete value W each time a value is deleted until the discrete value W satisfies being less than the preset value Y2. When the number of deletions r is greater than the preset value Y3, then take the mean value of the maximum and minimum values in He as the red channel calculation value E1 corresponding to the target region block of the target image. When the number of deletions r is less than or equal to the preset value Y3, then take the mean value Hp of He as the red channel calculation value E1 corresponding to the target region block of the target image, where the specific values of Y2 and Y3 are set by relevant personnel according to specific application scenarios and requirements; A3: Repeat step A2 to calculate and obtain the red channel calculation values Ei corresponding to the target region blocks in each main product image; Obtain the value Ez in the red channel calculation value Ei that satisfies the preset screening condition G, where z is the number of values in Ei that satisfy the preset screening condition L, z ≥ 1. Compare the quantity z with the preset threshold Y4. When the quantity z is greater than the preset threshold Y4, it indicates that the number of values in Ei that satisfy the preset screening condition L is relatively large, and the mean value of Ei is representative. Furthermore, define the mean value of Ei as the red channel reference value MA1 corresponding to the target region block. When the quantity z is less than or equal to the preset threshold Y4, it indicates that the number of values in Ei that satisfy the preset screening condition L is relatively small, and the mean value of Ei is not representative. Furthermore, define the mean value of the maximum and minimum values in Ei as the red channel reference value MA1 corresponding to the target region block, that is, MA1 = (MA min + MA max ) / 2, where MA min and MA max are the maximum and minimum values in Ei respectively; Here, the preset condition L is specifically: |Ei - Ep| ≥ Y5, where both Y4 and Y5 are preset values, and the specific values of Y4 and Y5 are determined by relevant personnel according to actual needs; A4: Repeat steps A1 - A3 to obtain the red channel reference values MAg corresponding to each image region block respectively, where g represents different image region blocks, g = 1, 2, ……, v, and v represents the number of image region blocks, and v is a positive integer; A5: In the same way as obtaining the red channel reference values MAg corresponding to each image region block respectively, analyze the green channel values and blue channel values corresponding to each pixel point in the image region block of each product main image, and then obtain the green channel reference value MBg and blue channel reference value MCg corresponding to each image region block respectively; The tile vector acquisition module performs vectorization processing on the red channel reference value MAg, green channel reference value MBg, and blue channel reference value MCg corresponding to each image region block respectively to obtain the reference tile vector Tg(MAg, MBg, MCg) corresponding to each image region block; The vector deviation value acquisition module inputs the to-be-delivered main image of the product to be delivered into the image data acquisition module, and then obtains the to-be-delivered red channel value FAg, to-be-delivered green - red channel value FBg, and to-be-delivered red - blue channel value FCg corresponding to each image region block in the to-be-delivered main image of the product to be delivered. Perform vectorization processing on the to-be-delivered red channel value FAg, to-be-delivered green - red channel value FBg, and to-be-delivered red - blue channel value FCg corresponding to each image region block in the to-be-delivered main image of the product to be delivered to obtain the to-be-delivered tile vector Dg(FAg, FBg, FCg) corresponding to each image region block in the to-be-delivered main image; Through the formula: ; Calculate the vector deviation value Xg between the to-be-delivered red map block vectors Dg(FAg, FBg, FCg) corresponding to each image region block in the to-be-delivered main map image and the reference map block vectors Tg(MAg, MBg, MCg) corresponding to each image region block respectively; The deviation coefficient acquisition module analyzes and compares the vector deviation value with a preset deviation threshold Y5, and obtains the deviation coefficient of the to-be-delivered main map image according to the analysis and comparison result. The specific method is as follows: Obtain the number f of vector deviation values Xg greater than the preset deviation threshold Y5, and define the ratio of f to the number v of image region blocks as the deviation coefficient K of the to-be-delivered main map image. The specific value of the preset deviation threshold Y5 is determined by relevant personnel according to actual needs and market research; The delivery flag generation module compares and analyzes the deviation coefficient K with a preset value Y6, and generates a recommended delivery flag or a non-recommended delivery flag according to the analysis result. The specific method is as follows: When K ≤ Y6, it indicates that the main map of the to-be-delivered product is visually similar enough to the main maps of the same type of products of the to-be-delivered product, and this main map can be accepted as the image for market delivery. Furthermore, a recommended delivery flag is generated; When K > Y6, it indicates that there are significant visual differences between the main map of the to-be-delivered product and the main maps of the same type of products of the to-be-delivered product. It is necessary to adjust or optimize the main map to better attract the target market, and a non-recommended delivery flag is generated; By performing image segmentation on the product main map and through complex red, green, and blue channel value analysis, the reference values and vectors of each image region block are obtained. The red, green, and blue channel reference values of each image region block are vectorized to obtain the reference map block vectors corresponding to each image region block respectively. The to-be-delivered product main map image is input into the image data acquisition module to obtain the red, green, and blue channel values of each region block of the to-be-delivered main map image and vectorize them to obtain the to-be-delivered map block vectors. Then, calculate the vector deviation value between it and the reference map block vector, and compare and analyze the vector deviation value with the preset deviation threshold to obtain the deviation coefficient of the to-be-delivered main map image, which is used to measure the difference degree between the to-be-delivered main map and the calibrated product main map. Compare and analyze the deviation coefficient with the preset value, and generate a recommended delivery flag or a non-recommended delivery flag according to the result, providing a scientific basis for the delivery decision of the product main map. It not only improves the exposure rate and click-through rate of the product, but also promotes the growth of sales volume, brings higher benefits to merchants, reduces the delivery risk, improves the success rate of products on cross-border e-commerce platforms, and at the same time reduces the waste of resources caused by unreasonable delivery.
