Commodity purity detection method for vertical air curtain cabinet

Abstract

The invention provides a commodity purity detection method for a vertical air curtain cabinet, the vertical air curtain cabinet comprises an air curtain cabinet, cameras, an IOT module and a data processing center, the cameras are mounted on the inner sides of the left and right side plates of the air curtain cabinet, the cameras are wide-angle cameras, lenses of the cameras are set to be adjustable heating lenses, and the data processing center is connected with the IOT module. Detection is carried out through the following method: a data processing center sends a photographing instruction to an IOT module, and the IOT module controls a camera to photograph and sends a picture obtained by photographing to the data processing center; step 2) the data processing center obtains and processes pictures shot by the cameras on the left and right sides; and step 3) the data processing center extracts the original standard commodity distribution image from the database, compares the original standard commodity distribution image with the fused complete image, compares the feature information of each commodity one by one, and judges whether the commodity is a target commodity, and the method can deal with the current situation of a wide air curtain cabinet and accurately reflect the purity of the commodity.

Description

technical field [0001] The invention relates to the field of purity detection of commercial refrigerators, in particular to a commodity purity detection method of a vertical air curtain cabinet. Background technique [0002] At present, the types of commercial display refrigerators in China are becoming more and more perfect. As operators of certain types of goods, they usually put corresponding display cabinets along with them when they put products on the market.

AI Technical Summary

Problems solved by technology

[0005] For vertical air curtain cabinets, there is no cabinet door, and usually there is no interaction process, and the lack of trigger conditions makes the existing methods unsuitable, and the installation and shooting angle of the camera are not easy to deal with

[0006] In addition, the width of the vertical air curtain cabinet is usually wide, the radiation range of a single camera is not enough, the installation position is not easy to determine, the recognition rate is not high, and due to the width and angle restrictions, distant products are blocked, resulting in recognition errors
