Abstract

The invention discloses a bar code recognition method, which is applied to the field of image recognition, and comprises the following steps: obtaining a first image which comprises a first target bar code; decoding the first image through a first decoding method; if the decoding result is not obtained, obtaining a second image, wherein the second image comprises a second target bar code, and the first target bar code and the second target bar code correspond to the same bar code; decoding a second target image through the first decoding method, and if a decoding result is not obtained, decoding the second target image through a second decoding method, wherein the decoding success rate of the second decoding method is higher than the decoding success rate of the first decoding method for bar codes with same image features. According to the method, different decoding strategies are adopted for multiple frames of images, so that the problems of long single-frame time consumption and large calculation power caused by complex attempts can be reduced.

Description

technical field [0001] The present application relates to the field of image recognition, and in particular, to a barcode recognition method and related equipment. Background technique [0002] The real-time code scanning function has the function of identifying product barcodes and QR code pictures, such as reading 1D codes on ordinary product packaging, QR codes for receipt and payment, etc. It supports a wide range of code types, supports complex scenarios, and quickly Response is the goal that real-time code scanning needs to achieve. [0003] The barcode reader can sequentially capture multiple frames of images based on the image capture parameters, and use multiple decoding methods to decode the acquired image frames in series until a decoding result is obtained. However, in the prior art, a serial decoding strategy in a fixed manner is used for each frame of image, which requires relatively large computing power and time. SUMMARY OF THE INVENTION [0004] The embo...
