Problems solved by technology

[0003] Existing electronic scales usually only have the functions of weighing and pricing. Most of the domestic research on smart scales focuses on improving the accuracy. For modern science and technology such as image recognition technology, pressure sensing technology, and big data, it is possible to identify fruits and vegetables, Research on smart electronic scales that automatically weigh is uncommon
[0004] In addition, although the use of desktop electronic scales in farmers' markets and shopping malls is quite common, with the development of the retail industry, the types of commodities in supermarkets are becoming more and more diverse. At this time, only traditional electronic scales are used for weighing and The maintenance efficiency of manual records is low, and the probability of errors is difficult to accurately control, which consumes manpower and affects customer experience

Embodiment 1

[0037] see figure 1 and figure 2 , figure 1 is a side view of the smart scale provided by the embodiment of the present invention, figure 2 It is the front view of the smart scale provided by the embodiment of the present invention. As shown in the figure, the smart scale based on image recognition includes a scale body, and the scale body includes a weighing platform 1, a camera 2 and a display 3; A pressure sensor is arranged on the table 1, and the camera 2 is arranged above the weighing table 1 for collecting images of items to be weighed;

[0038] The inside of the scale body is provided with a central processing unit, and the central processing unit is used to divide the item image into a plurality of regions, and extract color features and texture features of each region; Fuzzy processing, and compress and upload to the cloud for feature comparison, and obtain the item type that matches the weighing item determined based on the feature comparison result; determine ...

Embodiment 2

[0077] An embodiment of the present invention provides a smart scale system, including a management background connected by mutual communication and the above-mentioned smart scale, and the management background is used to determine the transaction status of the item according to the transaction information of the weighing item uploaded by the smart scale; Transaction information includes item type, weight, price, and transaction time.

[0078] In this way, the smart scale uploads the transaction information of the weighing items to the management background in real time, and the management background realizes the statistical analysis of sales data and market average prices through corresponding management programs, and assists merchants to further adjust sales conditions.

Embodiment 3

[0080] see image 3 , image 3 It is a flow chart of a weighing method of an intelligent scale provided by an embodiment of the present invention, such as image 3 As shown in, the weighing method of the smart scale is used for the above-mentioned smart scale based on image recognition, and specifically includes the following steps:

[0081] S301: Obtain the item image collected by the camera;

[0082] S302: Divide the item image into multiple regions, and extract color features and texture features of each region;

[0083] S303: Carry out feature blurring processing on the extracted color features and texture features, compress and upload them to the cloud for feature comparison, and obtain the item type determined based on the feature comparison result that matches the weighed item;

[0084] S304: Determine the price of the item to be weighed according to the weighing information collected by the pressure sensor and the type of the item.
