Automatic identification system and method for commodities based on image feature matching

Abstract

The embodiment of the invention discloses an automatic identification system and method for commodities based on image feature matching, which are used in the field of information systems and are used for overcoming the defect of the traditional bar code process for commodity feature identification in a commodity sales system so as to provide an accurate real-time commodity feature identification scheme. The system comprises an image processing unit and a commodity information system, wherein the image processing unit is used for collecting the image data of the current commodity in real time and processing the image data of the current commodity to extract image feature information; the commodity information system is used for storing the image feature information of the commodity, and looking up and matching the image feature of the current commodity according to the image feature information of the commodity, which is collected in real time, and the current commodity is identified. In the automatic identification system, the image processing unit is used for collecting commodity images, processing and communicating, the commodity price is synchronously identified by the image identification process, and thus the automatic identification system has the advantages of high identification speed, high precision and favorable popularization and application values.

Description

technical field [0001] The present invention relates to the field of information systems, in particular to a product automatic identification system and method based on image feature matching. Background technique [0002] In the early days of the commodity information system, the identification and entry of commodity prices were often done manually. In such a way, not only the amount of data is very large, the labor intensity is high, but also the bit error rate of the data is high, and it also loses the meaning of real-time. For the identification of commodity prices, digital barcode scanning technology is generally used: almost all open-shelf commodity packages will have barcodes, that is, commodity codes. [0003] A barcode is a graphic identifier that arranges multiple black bars and blanks with different widths according to certain coding rules to express a set of information. The barcode is the "account" or "ID card" of the commodity, and its coding follows the prin...
