Problems solved by technology

[0004] It can be seen that most of the above-mentioned existing barcode detection methods can only be applied in the "vertical" situation, that is, the user needs to manually adjust the alignment of the barcode area with the border of the scanning frame to identify the barcode
In addition, when there are multiple barcode areas in the field of view, the user needs to scan them one by one, which increases time consumption and inconvenience of operation

Abstract

The invention provides a bar code detection method, a bar code detection device and electronic equipment. According to the invention, an image acquired by the equipment is converted into a grayscale image, histogram equalization is performed, the image is segmented, candidate bar code lines which are similar to the bar code line contour are selected, the weight of each candidate bar code line is re-estimated, the rotating direction is acquired through classified statistics so as to perform rotation correction on an image to be processed, and finally bar code information is acquired through performing recognition and segmentation on a bar code region in the corrected image and decoding. Bar code detection and recognition are enabled to have good robustness for angle changes, and the complexity of detection operations is reduced.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a barcode detection method, a barcode detection device and electronic equipment. Background technique [0002] Barcode (Barcode) arranges multiple black bars and spaces of different widths according to certain coding rules to express a set of graphic identifiers for 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 location, category, date and many other information, so it is widely used in many fields such as commodity circulation, book management, postal management, banking system It is widely used, making the identification and flow of items very convenient. [0003] Today, more and more devices are able to capture ...
