Abstract

This application relates to the technical field of two-dimensional code recognition, and discloses a method for determining the decoding direction of a two-dimensional code, including: obtaining a two-dimensional code image; obtaining several parallel scanning line segments in the two-dimensional code image; respectively determining Two-dimensional code boundary points of each of the scanning line segments; fitting each of the two-dimensional code boundary points to obtain a two-dimensional code boundary line; determining a decoding direction according to the two-dimensional code boundary line. In this way, by acquiring several scanning line segments, respectively determining the boundary points of the two-dimensional code on each scanning line segment, fitting the boundary points to form the boundary line of the two-dimensional code, and determining the decoding direction of the two-dimensional code by the boundary line of the two-dimensional code, no need to The full-image processing of the two-dimensional code image can reduce the amount of computation for determining the decoding direction of the two-dimensional code. The application also discloses a device, an electronic device and a storage medium.

Description

technical field [0001] The present application relates to the technical field of two-dimensional code identification, for example, to a method and device for determining the decoding direction of a two-dimensional code, electronic equipment, and a storage medium. Background technique [0002] Stacked two-dimensional barcodes, whose coding principle is based on one-dimensional barcodes, are stacked into two or more lines as needed. The premise of decoding the stacked QR code is to correctly obtain the direction of the code word. The determination of the decoding direction of the existing stacked two-dimensional code depends on the location of the code map. Based on the rich edge information in the stacked two-dimensional code image, combined with mathematics, morphology and other methods, the gradient feature is used to transform the stacked two-dimensional code The code is segmented from the background to obtain the decoding direction of the stacked QR code. [0003] In th...
