Embodiment 1

[0035] Such as Figure 1 ~ Figure 2 As shown, a kind of intelligent scale based on image recognition of the present invention comprises scale body 1, and scale body 1 comprises pressure sensor, A / D converter and support, and scale body 1 is provided with camera 2, display screen 3 and processor, Both the camera 2 and the pressure sensor are connected to the processor;

[0036] A single-chip microcomputer is arranged in the scale body 1, and the single-chip microcomputer includes an image recognition module, a calculation module, a two-dimensional code module and a UI visualization module, and the single-chip microcomputer is connected with the processor.

[0037] In the above embodiment, the A / D converter is the hx711 chip; the pressure sensor and the A / D converter are detachably installed on the bracket; the camera is connected to the processor through a plug-in cable; the single-chip microcomputer is a Raspberry Pi single-chip microcomputer.

[0038] Such as image 3 As sh...

Embodiment 2

[0047] This embodiment is an improvement on the technical solution based on Embodiment 1.

[0048] Such as Figure 1 ~ Figure 2 As shown, the present invention is an intelligent scale based on image recognition. Further, the bottom of the camera 2 is provided with a movable base 4, the scale body 1 is provided with a fixed base 5, the fixed base 5 is provided with a chute, and the movable base 4 is located on the chute. In the groove, and can move along the chute.

[0049] In the above-described embodiment, the chute is a T-shaped groove or a dovetail groove; the camera 2 can be installed embedded or independently, and the embedded installation saves more space. When installed independently, it is convenient to adjust the shooting angle and shooting distance, so as to obtain better image effect; the camera 2 is connected to the processor through the connecting wire 6, and the scale body 1 is provided with a clamping slot 7, the connecting wire 6 can be fixed in the clamping s...

Abstract

The invention discloses a smart scale based on image recognition. The smart scale comprises a scale body. The scale body comprises a pressure sensor, an A / D converter and a bracket. The scale body isprovided with a camera, a display screen and a processor. The camera and the pressure sensor are both connected to the processor. A single-chip microcomputer is disposed in the scale body, comprises an image recognition module, a calculation module, a two-dimensional code module and a UI visualization module, and is connected with the processor. The smart scale can quickly and automatically identify the type of a commodity, matches the correct unit price with the commodity, and then calculates the correct total price to print a barcode. During the use period, except some products that are particularly confusing and require manual intervention, the whole process is fully automatic. The amount of manual assistance can be greatly reduced, thereby not only the labor cost of a supermarket is reduced, but also the fully automatic operation can greatly improves the weighing efficiency.

Description

technical field [0001] The invention relates to the field of electronic scales, in particular to an image recognition-based intelligent scale. Background technique [0002] At this stage, the vast majority of commercial scales actually used in the market are still traditional electronic scales. Traditional electronic scales require the salesperson to manually enter the unit price of the commodity or the commodity code to obtain the unit price. Since the price of each commodity is different every day, the method of entering the unit price is easy to remember the wrong price, which is a great test for the memory of the salesperson. Although the way of inputting the code can change the unit price by changing the database, the code is lengthy and difficult to remember, requiring a large number of skilled professionals to operate. Contents of the invention [0003] The purpose of the present invention is to provide a smart scale based on image recognition to solve the problem ...
