Embodiment Construction

[0053] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0054] The present invention proposes an image code generation and analysis method that can automatically correct the geometric distortion of the coded image without a position mark, and the generated coded image is as follows: figure 1 The image indicated by the middle label 102 is shown.

[0055] figure 2 It is a flow chart of functional module composition and processing for generation and analysis of an image code without a position mark provided by the implementation example of the present invention, which includes an encoding module for image code generation and a decoding module for image c...

Abstract

The invention provides an image code having no position marks and a generation and analysis method thereof. The method comprises an encoding / decoding method of the image code having no position marks. The image code encoding process is characterized by carrying out synthesis on an original image, additional information and a geometric correction template through digital watermarking coding technology to generate an encoded image having the additional information; and the image code analysis process is characterized by inputting the encoded image through input devices, such as a mobile phone camera and a scanner, carrying out geometric distortion correction on the input image through the geometric correction template in the image, and then, analyzing the additional information in the image through the digital watermark extraction technology. Compared with a two-dimension code or a image code having the position marks, the image code can realize geometric distortion correction of the encoded image without special position marks, and the additional information in the encoded image can be read correctly, thereby realizing fast connection between devices of an intelligent mobile phone and a computer and the like and the additional information; and meanwhile, the coded image is more beautiful and generous and more diversified in form.

Description

technical field [0001] The invention belongs to the field of image processing and automatic image recognition, and in particular relates to an image code without visible positioning marks used for embedding information in an image and a method for generating and analyzing the same. Background technique [0002] With the advent of the mobile Internet era, QR codes have gradually become the keyboard of smartphones and the access terminal of the Internet, and are widely used in various fields of society and our daily life. However, the existing two-dimensional codes cannot intuitively or preliminarily display the information contained in them, and often need to add text descriptions; and their black and white patterns appear dull and not beautiful enough. [0003] Image code technology uses digital watermarking technology to embed text and website information into images, and at the same time scans the printed image containing watermark information through the camera or scanner...
