Embodiment Construction

[0042] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0043] The main solution of the embodiment of the present invention is: based on a given graphic, construct at least one logo graphic to generate a data band for data embedding; divide the generated data band according to a preset method to form several data segments ; According to the preset mapping relationship between the data and the color value of the fill color, fill each data segment with a fill color corresponding to the data to be embedded, so as to generate a data embedding graph.

[0044] Due to the difficulty in coordinating the embedding of data and the appearance of carrier graphics in the prior art, the present invention provides a solution to embed data into graphics in a way that is not easily perceived by the human eye, without destroying the visual beauty of the graphics while ensuring that the data ...

Abstract

The invention discloses a data embedding method. The data embedding method comprises the steps of constructing at least one marking graphic based on a given graphic to generate a data tape for data embedding, dividing the generated data tape in a preset manner to form several data segments, and according to a preset mapping relationship between data and color values of fill colors, filling each data segment with a fill color corresponding to the to-be-embedded data to generate a data embedding graphic. The invention also discloses a data reading method, a device and a computer readable storagemedium. The data embedding method, the data reading method, the device and the computer readable storage medium embed the data into the graphic in a manner that is not easily perceived by the human eyes, do not destroy the visual aesthetics of the graphic under the premise that the data can be reliably read by a machine, and solve the problem of the difficult coordination between the data embedding and the appearance of the carrier graphic.

Description

technical field [0001] The invention relates to the field of data coding and image pattern recognition, in particular to a data embedding method, a data reading method, a device and a readable storage medium. Background technique [0002] All kinds of existing matrix two-dimensional codes use two kinds of dark and light rectangular blocks to form a large rectangular pattern with a specific recognition mode. One of the main design purposes is to match the early digital imaging technology and support Terminal devices with weak computing power can identify it in real time. One of the main shortcomings of this type of two-dimensional code is that it needs to occupy an exclusive area on the surface of the carrier. When they are applied to printed publications or advertisements, it is difficult to maintain the consistency of layout and visual aesthetics with the graphic content, and it is also difficult to integrate with other graphics. typesetting. Therefore, it is necessary to...
