Image code applied to information processing, as well as device and method for generating and analyzing image code

Abstract

The invention provides an image code applied to information processing, as well as a device and a method for generating and analyzing the image code. The image code comprises a standard image area, at least one image, at least one section of information flow, and four position identification graphs, wherein the standard image area is filled with the at least one image, the at least one section of the information flow is implanted into the at least one image by utilizing the digital watermark technology, and the four position identification graphs are arranged at different positions of the standard image area, are arranged at four top corners of the standard image area, and comprise one feature position identification graph and three basic position identification graphs; the three basic position identification graphs are completely the same, and are different from the feature position identification graph. According to the image code applied to the information processing, as well as the device and the method for generating and analyzing the image code, information of the image code can be quickly obtained by an intelligent mobile phone, and quick linkage between the intelligent mobile phone and Internet can be achieved by utilizing self content of the images (graphs); compared with a two-dimension code, the image code has the advantages that the appearance is beautiful and elegant, and the information content can be directly displayed; the content information is safer and is hard to tamper or forge.

Description

technical field [0001] The invention belongs to the field of image processing and automatic identification, and in particular relates to an image code used for information processing and a device and method for generating and analyzing it. 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 rigid and mechanical, not beautiful enough, and are not compatible with exquisite posters, business cards, and packaging of high-end products. There is no sense of unity and coordination at all. In order to make the appearance of the two-dimensional code more elegant, the patent application CN 1036...

Problems solved by technology

[0005] However, in order to take pictures with a smartphone and read the watermark information in the image printed on paper (or displayed on an electronic screen), it is necessary to first overcome the three distortions of the image caused by the camera of the smartphone, (1) due to The image scale imbalance caused by the uncertainty of the distance between the mobile phone and the image; (2) The image angle rotation caused by the uncertainty of the horizontal angle between the mobile phone camera and the image; (3) The difference between the mobile phone camera plane and the image plane Image distortion caused by parallelism
