Problems solved by technology

However, when identifying products, the light of the code scanning gun is often not perpendicular to the barcode. At this time, it is necessary to adjust the scanning direction of the code scanning gun. The operation is complicated and the barcode recognition efficiency is low.

Abstract

The invention provides a generation method and device of bar codes, a recognition method and device of bar codes, print, electronic equipment and a computer readable storage medium. The generation method of bar codes includes the steps: obtaining a dotted line segment based on a bar code generated through a preset encoding mode and an intersection of straight lines perpendicular to black strips inthe bar code; and taking any one of two endpoints of the dotted line segment as the center of a circle, and rotating the dotted line segment by 180 degrees to generate a semicircular barcode. The generation method of bar codes obtains a dotted line segment based on a bar code generated through a preset encoding mode and an intersection of straight lines perpendicular to black strips in the bar code, takes any one of two endpoints of the dotted line segment as the center of a circle, and rotates the dotted line segment by 180 degrees to generate a semicircular barcode. As the semicircular barcode is generated by rotating the dotted line segment by taking any one endpoint as the center of a circle, the bar code can be recognized at an arbitrary angle when the bar code recognition device scans the semicircular bar code by passing the center of the circle.

Description

technical field [0001] The present application relates to the technical field of graphic codes, in particular to a method and device for generating barcodes, a method and device for identifying barcodes, printed matter, electronic equipment, and computer-readable storage media. Background technique [0002] With the rapid expansion and development of the retail industry and the consumer market, the growth of the barcode label business has been promoted, and more and more places need to use labels and barcodes (barcode). 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. A common barcode is a parallel line pattern formed by black bars (abbreviated as bars) and white bars (abbreviated as empty) with very different reflectivity. Barcodes can mark the country of origin, manufacturer, product name, production date, book classification number, mail start and end lo...
