Rapid three-dimensional code generation method and device and storage medium

Abstract

The invention relates to a quick three-dimensional code generation method, which comprises the following steps of: inputting a background picture, and determining size information of the background picture; inputting information needing to be coded; inputting size information of a target three-dimensional code picture expected to be generated; the deviation between the size of the background picture and the size of the target three-dimensional code picture is calculated, size adjustment processing is carried out on the background picture according to the deviation, and a background base picture with the same size as the target three-dimensional code picture is generated; generating a two-dimensional code coding matrix by using the coding information, and determining the size of each module in the coding matrix according to the size of the target three-dimensional code picture; generating a mask image which has the same size as the target three-dimensional code picture and is transparent, mapping the position of each module in the coding matrix into the mask image, and generating a corresponding module image in the mask image according to the size of the module; and fusing the mask image and the background base image to obtain a final three-dimensional code picture.

Description

technical field [0001] The invention relates to a rapid generation method, device and storage medium of a three-dimensional code, and belongs to the technical fields of generation and processing of coding symbols and image processing. Background technique [0002] The three-dimensional code in the present invention refers to a dot-matrix code that produces a certain visual effect and records data information after the fusion of images and code-making information. In addition to being recognized by machines, this kind of code also provides third-dimensional visual image information that can be quickly identified for natural people, and has the characteristics of high recognition and aesthetics. [0003] The fusion processing of the base map and data is a time-consuming process. It is necessary to calculate the color and range size of each module, especially in the case of both artistry and readability, which usually requires a large amount of calculation. At present, in orde...

Problems solved by technology

[0004] These methods are too pursuing visual effects that are more suitable for human eyes, and require a large amount of calculations, which cannot meet the needs of fast coding in low-configuration or embedded devices; in addition, these methods usually set the central area to a narrow range, As a result, it is easy to make mistakes when making 0 and 1 judgments and cannot read accurately

In the existing method, it is necessary to calculate the edge feature of the base map or the average brightness threshold of the base map, and adjust the color and brightness of each module according to the feature or threshold, which requires a large amount of calculation. The image usually takes more than 1 second, so it cannot well meet the coding application scenarios with high real-time requirements; at the same time, the completed code is too pursuit of visual effects (such as attached Figure 10 ), the reading efficiency is low, and it is difficult to meet the scene that requires fast reading and decoding
