Abstract

The invention discloses a bar code positioning method. The method comprises the following steps: receiving a to-be-positioned image acquired by image acquisition equipment; performing segmentation processing on the to-be-positioned image through an adaptive threshold algorithm, and determining an express sheet area; carrying out edge detection on the express sheet area by utilizing a Sobel operator to obtain a gradient intensity graph; carrying out bar code positioning in the gradient intensity graph, and determining a bar code area. According to the bar code positioning method, the barcode positioning accuracy can be effectively improved, and normal identification of subsequent barcodes is ensured. The invention further discloses a bar code positioning device and equipment and a computerreadable storage medium, which all have the above beneficial effects.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a barcode positioning method, and also to a barcode positioning device, equipment, and computer-readable storage medium. Background technique [0002] With the development of information technology, barcode technology has been widely used in various fields of automatic management. It has the characteristics of accuracy, speed, convenience and economy, and has brought great convenience to the transaction management of various industries. [0003] A barcode is a graphic identifier used to express a set of information. Specifically, it can mark the country of production, manufacturer, product name, production date, book classification number, mail origin, category, date and other information. When it is identified and detected by professional identification equipment, various relevant information can be obtained, and in the process of barcode detection, the positi...
