Example Embodiment

[0029] The specific embodiments of the present invention are given below in conjunction with the drawings, but the present invention is not limited to the following embodiments. According to the following description and claims, the advantages and features of the present invention will be clearer. It should be noted that the drawings all adopt a very simplified form and all use imprecise ratios, which are only used for the purpose of conveniently and clearly assisting in describing the embodiments of the present invention.

[0030] The single image characteristic of the black and white stripes that the barcode has in common enables the SURF feature matching between any two barcode images to be carried out. The present invention utilizes this characteristic, firstly through rough matching between the barcode template image and the commodity image containing the barcode, the position of the barcode is quickly located; and then the position of the barcode is accurately located by el...

Abstract

The invention provides a method for rapidly positioning and recognizing a one-dimensional barcode of an outer commodity package. The method includes the following steps that a commodity barcode image is acquired; feature matching is conducted on a barcode template image and the acquired commodity barcode image, so that a positioning region of the current commodity barcode is acquired; the commodity barcode image is segmented and restored and then the barcode is recognized, so that commodity information is acquired. According to the method for rapidly positioning and recognizing the one-dimensional barcode of the outer commodity package, the one-dimensional barcode on the outer commodity package is automatically and rapidly positioned, a barcode region is segmented, the barcode is finally recognized, and a whole commodity is accurately recognized. The method has the advantages that the barcode is rapidly, accurately and automatically recognized and the method is suitable for the commodity image in a complex background.

Description

technical field [0001] The invention relates to the field of commodity barcode identification, and in particular to a method for quickly locating and identifying one-dimensional barcodes on commodity outer packaging. Background technique [0002] Traditional barcode identification methods mainly include photoelectric identification methods, radio frequency identification and image-based barcode identification methods. [0003] The photoelectric identification method is very mature and widely used in the market. However, this kind of barcode technology has a poor ability to recognize polluted barcodes, and to achieve an ideal recognition effect requires higher barcode printing quality. [0004] As a new type of barcode identification technology, radio frequency identification (RFID) performs non-contact two-way communication through induction between radio frequency tags and radio frequency readers, radio waves or microwave energy to achieve data exchange and achieve identif...
