Embodiment Construction

[0079] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.

[0080] Before explaining the barcode correction method provided by the embodiment of the present application in detail, the application scenario and implementation environment provided by the embodiment of the present application will be introduced first.

[0081] The barcode correction method provided in the embodiment of the present application can be applied to various scenarios. For example, in the field of logistics and warehousing, items can usually be identified, retrieved, etc. through the barcode on the item. However, for items with non-planar shapes, the barcodes on the items may be distorted, and the barcodes on columnar items such as bottles and cans will have overall surface distortion. Moreover, after s...

Abstract

The embodiment of the invention discloses a bar code correction method and device, equipment and a storage medium, and belongs to the technical field of data processing. The method comprises the steps of performing semantic segmentation on a target image to obtain a background area and a code area in the target image, performing bar code recognition on the code area to determine whether the code area is a bar code or not, determining a plurality of contour points of the code area under the condition that the code area is the bar code, determining correction parameters based on position information of the plurality of contour points, based on the correction parameters, correcting the bar code in the target image to obtain a standard distortionless bar code, and decoding the standard distortionless bar code. According to the embodiment of the invention, the target image is subjected to semantic segmentation to determine the position information of the code area and each angular point, so that the position of the code area can be accurately recognized in complex scenes such as low contrast and fouling, and the influence of the complex scenes on the recognition of the position of the code area is avoided.

Description

technical field [0001] The embodiments of the present application relate to the technical field of data processing, and in particular to a barcode correction method, device, equipment and storage medium. Background technique [0002] Barcodes include one-dimensional barcodes and two-dimensional barcodes. One-dimensional barcodes are also called barcodes, and two-dimensional barcodes are also called two-dimensional codes. Barcodes can be scanned by photoelectric scanning equipment to realize automatic identification of information. However, when the barcode is attached to a non-planar material, the barcode will be distorted and a distorted barcode will be formed, thereby reducing the barcode recognition rate. Therefore, there is an urgent need for a barcode correction method to correct the barcode in the distorted form to the undistorted form. [0003] In the related art, when correcting the barcode, traditional methods such as binarization are usually used to extract the b...
