Problems solved by technology

However, in related technologies, the recognition accuracy of two-dimensional codes, especially deformed two-dimensional codes, is low. Pasted on a curved surface object, resulting in nonlinear deformation of the acquired two-dimensional code, usually cannot be accurately recognized for this type of two-dimensional code

Abstract

The invention provides a distorted two-dimensional code recognition method and device, a storage medium and an electronic device. The method comprises the following steps: determining a first group ofkey points in a target template pattern as a group of control points of thin plate spline fitting operation; obtaining a group of target values of the thin plate spline fitting operation according tothe position coordinates of the group of control points in the two-dimensional code image; performing thin plate spline fitting operation according to the group of control points and the group of target values to obtain a target value of a target parameter in a thin plate spline interpolation function; determining mapping coordinates of a central point of a module in a coding region in the targettemplate pattern in the two-dimensional code image according to the thin plate spline interpolation function to obtain a group of mapping coordinates; and identifying the two-dimensional code image according to the group of mapping coordinates. According to the method and the device, the technical problem of relatively low recognition accuracy of the distorted two-dimensional code in an uncertainform in related technologies is solved.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for identifying a distorted two-dimensional code, a storage medium and an electronic device. Background technique [0002] Two-dimensional codes are more and more widely used, and the original data corresponding to the two-dimensional code can be obtained by identifying the two-dimensional code. However, in related technologies, the recognition accuracy of two-dimensional codes, especially deformed two-dimensional codes, is low. Being pasted on a curved surface object, the obtained QR code is deformed non-linearly, and it is usually impossible to accurately identify this type of QR code. [0003] Aiming at the technical problem of low recognition accuracy of distorted two-dimensional codes in indeterminate forms in related technologies, no effective technical solution has been proposed yet.
