Two-dimensional code pre-deformation design method on conical surface

Abstract

The present invention discloses a two-dimensional code pre-deformation design method on a conical surface. The method comprises the steps of laterally stretching an original two-dimensional code image to obtain a first deformation two-dimensional code image; and longitudinally stretching the first deformation two-dimensional code image to obtain a pre-deformed two-dimensional code image. The laterally stretching operation and the longitudinally stretching operation are conducted according to a certain spatial geometry relation to realize the image mapping. According to the above technical scheme of the two-dimensional code pre-deformation design method on the conical surface, the original two-dimensional code image is pre-deformed according to the certain spatial geometry relation and the pre-deformed two-dimensional code image is printed on the plane of a conical presswork. In the curved-surface condition, the projection plane thereof is just a undistorted two-dimensional code. The two-dimensional code can be scanned and decoded at the center thereof by any decoding software. Therefore, the application range of the two-dimensional codes is improved.

Description

technical field [0001] The invention relates to the field of two-dimensional code design, in particular to a two-dimensional code pre-deformation design method on a conical surface. Background technique [0002] At present, with the rapid development of the mobile Internet, the rapid popularization of mobile intelligent terminals such as smartphones and tablets under the 3G / 4G mobile network environment, and the relative maturity of the two-dimensional code encoding and decoding technology, the application of two-dimensional codes is no longer subject to the constraints of space and time. The limitation of hardware equipment thus has an increasingly far-reaching impact on people's daily life. QR codes are widely used in various industries, such as logistics, manufacturing, transportation, security, tickets and other industries. Moreover, with the rapid development of global information and communication technology, various applications using mobile phones as terminals conti...

Problems solved by technology

[0003] However, the printing and placement of the current two-dimensional code is subject to certain restrictions. In the current technology, the two-dimensional code needs to be printed on a flat or nearly flat printed matter, or displayed on a flat terminal display screen, so that users can The code scanning APP in the mobile terminal can identify

However, if it is necessary to print or display the two-dimensional code pattern on the surface of a non-planar object, especially the surface of a cone, and the decoding function of the current code scanning software can be successfully scanned, it has become a problem to be solved.
